                                PROXY STATEMENT
                                    FOR THE

    This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Sierra Health Services, Inc., a Nevada
corporation, for use at the 2001 Annual Meeting of Stockholders of the Company
(the "2001 Annual Meeting") to be held at 10:00 a.m., local time, on Tuesday,
May 22, 2001, in the President's Auditorium at the Sierra Health Services
corporate complex, 2716 North Tenaya Way, Las Vegas, Nevada, and at any
adjournments thereof. The approximate date on which this Proxy Statement and the
accompanying proxy card are first being sent to the Company's stockholders is
April 19, 2001.

                          VOTING OF PROXY; REVOCATION

    A proxy in the accompanying form that is properly executed, returned, and
not subsequently revoked will be voted in accordance with instructions contained
thereon. If no instructions are given with respect to the matters to be acted
on, proxies will be voted as follows: (i) for the amendment to the Company's
Bylaws as discussed herein, (ii) for the election of the six nominees described
herein, (iii) for the ratification of the appointment of auditors, (iv) against
the stockholder proposal, and (v) otherwise in accordance with the best judgment
of the person or persons voting the proxy on any other matter properly brought
before the 2001 Annual Meeting. Any stockholder who signs and returns the proxy
may revoke it at any time before it is exercised by (i) delivering written
notice to the Secretary of the Company of its revocation, (ii) executing and
delivering to the Secretary of the Company a later dated proxy, or (iii) by
appearing in person at the 2001 Annual Meeting and expressing a desire to vote
his or her shares in person. See "Other Matters."

                            EXPENSES OF SOLICITATION

    The expenses of the preparation of proxy materials and the solicitation of
proxies for the 2001 Annual Meeting will be borne by the Company. In addition to
solicitation by mail, proxies may be solicited in person, by telephone, telecopy
or other means, or by Directors, officers and regular employees of the Company
who will not receive additional compensation for such solicitations. Corporate
Investor Communications, Inc. has been engaged by the Company to assist in the
solicitation of proxies for a fee of $3,000 plus their costs and expenses.
Although there is no formal agreement to do so, the Company will reimburse
banks, brokerage firms and other custodians, nominees and fiduciaries for
reasonable expenses incurred by them in forwarding the proxy soliciting
materials to the beneficial owners of the Company's Common Stock.

                               VOTING SECURITIES

    Holders of the Company's Common Stock, par value $.005 per share, as of the
close of business on March 26, 2001 will be entitled to notice of, and to vote
at, the 2001 Annual Meeting or any adjournments thereof. On that date, there
were 27,512,822 shares of Common Stock outstanding, the holders of which are
entitled to one vote for each share registered in their names with respect to
each matter to be voted on

                                       1

at the 2001 Annual Meeting, except as described below for the election of
Directors. The presence in person or by proxy (regardless of whether the proxy
has authority to vote on all matters) of the holders of record of shares
representing a majority of the total issued and outstanding shares of Common
Stock as of March 26, 2001 will constitute a quorum at the 2001 Annual Meeting.

    Stockholders are entitled to vote cumulatively for the election of Directors
if any stockholder gives written notice to the President or Secretary of the
Company not less than 48 hours before the 2001 Annual Meeting that such
stockholder desires the voting for the election of Directors be cumulative. If
cumulative voting is so invoked, each stockholder is entitled to the number of
votes equal to the number of shares held by such stockholder multiplied by the
number of Directors to be elected, and may cast all such votes for one nominee
or distribute them among the nominees. Discretionary authority is being sought
by the proxy holders to cumulate votes and distribute such votes among some or
all of the nominees in the event that cumulative voting is invoked.

    Assuming that a quorum is present at the 2001 Annual Meeting, Directors will
be elected by a plurality of the votes cast at the 2001 Annual Meeting by
holders of shares of Common Stock present in person or represented by proxy.
Approval of the amendment to the Bylaws requires the affirmative vote of the
stockholders who hold at least a majority of the voting power of the issued and
outstanding stock entitled to vote at the Annual Meeting. Approval of other
items at the 2001 Annual Meeting requires that the number of votes cast in favor
of the action exceeds the number of votes cast in opposition to the action.
Withholding authority to vote for Directors and broker non-votes will not affect
the election of Directors. Abstentions and broker non-votes will have the same
effect as a vote against the proposed amendment to the Bylaws, but will not
affect the outcome of the vote on other proposals.

ownership of the Common Stock of the Company as of March 26, 2001 (except as

ITEM NO. 1--AMENDMENT OF THE COMPANY'S BYLAWS

APPROVAL OF AMENDMENT TO THE COMPANY'S BYLAWS

    Stockholders will be asked to approve an amendment to the Sierra Health
Services, Inc. Bylaws at the Annual Meeting to increase the maximum size of the
Board to nine directors. Currently, the Bylaws specify that the maximum size of
the Board of Directors shall be six directors.

    During 2000, the Company sought to expand the size of the Board to increase
the number of independent directors to six. At that time, the Board also
included two senior executive officers. Due to the maximum size limitation of
seven directors set forth in the Bylaws, it became necessary for one director,
Erin E. MacDonald, then President of the Company, to step down from the Board to
accommodate six independent directors.

    In seeking approval of an amendment to the Bylaws to allow a maximum Board
size of nine, the Board seeks to enable the election of Ms. MacDonald again to
the Board. If the amendment is approved by stockholders, the size of the Board
will increase to eight, and Ms. MacDonald will be nominated to fill the newly
added Board seat. A maximum size of nine will enable the Board to add an
additional director without having to amend the Bylaws, if the Board determines
that an additional member would be in the best interests of the Company. If the
proposed amendment is not approved, the Board will remain at seven members and
Ms. MacDonald will not be nominated for election to the Board.

    The proposed amendment would change Article III, Section 3.02, of the
Company's Bylaws to read as follows (deletions overstruck and additions in BOLD
AND UNDERLINED):

    Section 3.02. Election, Number and Term of Office. The Board of Directors
    shall be not less than 3 nor more than 7 9 directors; provided, however,
    that in cases where all the shares of the Corporation are owned beneficially
    and of record by 1 or 2 stockholders, the number of directors may be less
    than 3 but not less than the number of stockholders. The number of directors
    may be fixed from time to time exclusively by the Board of Directors
    pursuant to a resolution adopted by a majority of the directors. The number
    of directors is currently SHALL BE fixed at six (6) FROM TIME TO TIME BY THE
    BOARD OF DIRECTORS. The directors shall be divided into two (2) classes, as
    nearly equal in number as possible, with the term of office of the first
    class and the term of office of the second class to expire in alternating
    years. At each annual meeting of stockholders, directors elected to succeed
    those directors whose terms expire at such meeting shall be elected for a
    term of office to expire at the second succeeding annual meeting of
    stockholders after this election. Directors shall be elected to serve their
    respective terms and until a successor shall have been elected and
    qualified, except in the event of death, resignation or removal. No director
    will be eligible to be elected to the Board after reaching the age of 75.
    Notwithstanding the foregoing, at least one-fourth in number of the
    directors of the Corporation shall be elected annually.

    The amendment to the Bylaws will be adopted if approved by the affirmative
vote of the stockholders who hold at least a majority of the voting power of the
issued and outstanding stock entitled to voting power at the Annual Meeting.

    THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF THE
AMENDMENT TO THE COMPANY'S BYLAWS.

ITEM NO. 2--ELECTION OF DIRECTORS

    The Board of Directors has fixed the number of Directors at seven. At the
2001 Annual Meeting of Stockholders, stockholders will be asked to approve an
amendment to the Bylaws that would permit the Board to be expanded up to nine
members. If that proposal is approved, the Board will immediately increase in
size to eight persons, and Erin E. MacDonald will be nominated to fill the
additional seat. If that proposal is not approved, Erin E. MacDonald will not be
nominated for election as Director. The

                                       5

Bylaws of the Company provide for two classes of Directors, as nearly equal in
number as possible, with each class serving for a term of two years. At the
Annual Meeting, the terms of Anthony M. Marlon, M.D., Thomas Y. Hartley, Anthony
L. Watson, Michael E. Luce and Albert L. Greene will expire. The Company's Board
of Directors has nominated Anthony M. Marlon, M.D., Thomas Y. Hartley, Anthony
L. Watson, and Michael E. Luce, for re-election to the Board for two-year terms.
The Company's Board of Directors has also nominated Albert L. Greene and,
subject to the approval of the proposed amendment to the Bylaws, Erin E.
MacDonald, for election to the Board for terms expiring at the 2002 Annual
Meeting of Stockholders and until their successors are duly elected and
qualified. With the exception of Ms. MacDonald, each of the nominees is
presently a member of the Board of Directors. Each of the nominees has consented
to being named herein and to serve if elected. The Company does not know of
anything that would preclude any nominee from serving if elected. If any nominee
becomes unable to stand for election as a Director at the meeting, an event not
now anticipated by the Board of Directors, the proxy may be voted for a
substitute designated by the Board of Directors. The identity and a brief
biography of each nominee for Director and each continuing Director is set forth
below. The proxy holders named on the accompanying proxy card intend to vote the
shares represented by each proxy authorizing votes for these nominees in favor
of the nominees, and if cumulative voting is invoked, to distribute, in such
proportion as they see fit, the votes represented by each such share among the
nominees. Proxies cannot be voted for a greater number of persons than the
number of nominees named.

such filing.

AUDIT COMMITTEE REPORT

    The Audit Committee reports as follows with respect to the audit of the
Company's consolidated financial statements for the fiscal year ended
December 31, 2000 (the "2000 Financial Statements"). The Audit Committee has
(i) reviewed and discussed with management the 2000 Financial Statements;
(ii) discussed with Deloitte & Touche LLP, the Company's independent certified
public accountants, the matters required to be discussed by the Statement of
Auditing Standards No. 61 (Communication with Audit Committees) which include,
among other items, matters related to the conduct of the audit of the 2000
Financial Statements; and (iii) received from Deloitte & Touche LLP disclosures
and the letter regarding their independence required by Independence Standards
Board Standard No. 1 (Independence Discussions with Audit Committees), and
discussed with Deloitte & Touche LLP that firm's independence. Based on the
foregoing review and discussions, the Audit Committee has recommended to the
Board of Directors that the 2000 Financial Statements as audited by Deloitte &
Touche LLP be included in the Company's Annual Report on Form 10-K for the
fiscal year ended December 31, 2000.

AUDIT FEES

    The aggregate fees billed by Deloitte & Touche LLP, the member firms of
Deloitte Touche Tohmatsu and their respective affiliates (collectively,
"Deloitte"), for professional services rendered for the audit of the Company's
annual financial statements for the year ended December 31, 2000, and for the

on Form 10-Q for that year were $515,000.

ALL OTHER FEES

    The aggregate fees billed by Deloitte for services rendered to the Company,
other than the services described above under "Audit Fees" and "Financial
Information Systems Design and Implementation Fees," for the year ended
December 31, 2000, were $1,801,000. The majority of these fees were for
consulting in connection with the Company's Texas restructuring initiatives and
the amended credit facility.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

    The Compensation Committee of the Board of Directors (the "Committee"),
which is composed entirely of non-employee Directors, is responsible for
developing and making recommendations to the Board with respect to the Company's
compensation policies. In addition, the Committee has the authority to determine
the annual compensation to be paid to the Chief Executive Officer and the
Company's other executive officers. During 2000, the four non-employee Directors
who served on the Committee also served as the Company's Stock Plan Committee,
which administered the Company's stock-based incentive compensation plans. In
some cases compensation decisions with respect to the Chief Executive Officer
and certain other executive officers are subject to the approval of a
subcommittee of the Compensation Committee and the Stock Plan Committee, the
three members of which qualify as "outside directors" for purposes of
Section 162(m) of the Internal Revenue Code (discussed below).

    The fundamental objectives of the Company's executive compensation programs
are: 1) to attract and retain superior individuals critical to the long-term
success of the Company; 2) to promote the achievement of the Company's annual
and long-term strategic goals; 3) to reward performance; and 4) to tie
executives' interests to the success of the Company to further encourage their
efforts to increase value to stockholders.

    To meet these objectives, the Company's executive compensation program
currently is structured to include base salary, annual bonus, long-term
incentive compensation in the form of stock options, and certain retirement,
severance, and insurance benefits, as well as various other benefits that are
generally available to all employees of the Company, including medical,
retirement, and employee stock purchase plans.

    In implementing the Company's compensation programs, the Committee's general
policy is to consider any significant effects of Section 162(m) of the Internal
Revenue Code. Section 162(m), under certain circumstances, disallows a public
company's tax deduction for certain compensation paid to the chief executive
officer and the four other most highly compensated executive officers serving at
year-end to the extent that compensation exceeds $1 million in any tax year.
Compensation that qualifies as "performance-based" compensation is excluded from
the $1 million deductibility cap, and therefore remains fully deductible. The
Committee has taken steps to ensure that annual incentive compensation payable
to the Chief Executive Officer, as well as compensation resulting from stock
options granted to all executive officers, qualify as "performance-based"
compensation and are, therefore, fully deductible by the Company. The
regulations under Section 162(m) impose a number of technical requirements in
order for such compensation to qualify as "performance-based." There can be no
assurance that compensation in excess of $1 million paid to any executive
officer will be fully deductible under Section 162(m). In addition, preserving
deductibility under Section 162(m) is only one of the Committee's considerations
in implementing the Company's executive compensation program, and generally is
not the most important consideration. The Committee (or the Board of Directors)
may conclude that compliance with Section 162(m) in connection with any one
element of compensation interferes with more important objectives of the Company
or imposes burdens or costs which outweigh the benefit of preserving full tax
deductibility under Section 162(m).

TOTAL COMPENSATION LEVELS

    The Committee intends that an executive officer's targeted compensation will
represent competitive compensation as compared to organizations that compete
with the Company for executive talent. In this way, the Company's executive
compensation program can promote long-term service by executives, reduce the
risk that talented and experienced executives will be recruited away from the
Company, and reward outstanding performance. To accomplish this, the Committee
intends that targeted annual cash compensation will approximate average
compensation payable by comparable companies, with long-term incentive
compensation providing potentially above-average compensation when performance
exceeds

                                       12

competitive levels, based primarily on growth in the value of shares of the
Company's stock. The Company from time to time engages the services of a
compensation consulting firm to review its executive compensation program and to
survey comparable healthcare companies and published industry averages to help
the Committee assess the implementation of its policies.

CASH COMPENSATION

    Each year, the Committee reviews the Chief Executive Officer's base salary
and sets the amount. In doing so, the Committee makes a subjective assessment of
the Chief Executive Officer's performance and the Committee's expectations with
regard to the Chief Executive Officer's future contributions to the Company. The
Committee may also consider competitive compensation data. For the other
executive officers, the Committee sets a permissible range of salary increases
and allows the Chief Executive Officer to set actual salaries within those
parameters based on each officer's individual performance and achievement of
both Company and individual goals. For all executives, the Committee also
considers the Company's policy governing annual "merit" salary increases for
employees generally. For 2000, the Committee authorized merit increases in
executive salaries ranging from 0% to 3%.

    The annual incentive bonus payment for the Chief Executive Officer and the
other executive officers under the Company's Cash Bonus Program is intended to
reward key employee performance for assisting the Company in achieving financial
success and maximizing stockholder value. For 2000, the Committee determined
that annual incentive bonuses would be payable based on achievement of a
targeted level of earnings per share, with additional performance measures
specified for some executives. For this purpose, earnings per share was to be
measured excluding acquisition-related charges, year 2000 charges,
non-operating, unusual charges, and positive and negative effects of
acquisitions completed in 2000. Achievement of the targeted earnings level was
necessary in order to fund the bonus pool, from which annual incentive bonuses
would be paid out. Based on job position, eligible employees are placed into
specific categories, each of which is entitled to a payout from the bonus pool
up to a maximum amount, expressed as a percentage of base salary. The target
annual incentive for the Chief Executive Officer represents a higher percentage
of base salary than that for other executive officers, in line with industry
practice and consistent with the Committee's view that Company performance more
closely reflects the Chief Executive Officer's individual performance. The
Committee authorized a potential bonus of 100% of base salary for the Chief
Executive Officer, 75% of base salary for the President, and amounts ranging
from 20% to 50% of base salary for other eligible employees. In 2000, the
Company's earnings per share, as adjusted, did not reach the minimum level
necessary to fund the annual incentive pool, so no annual incentive bonuses were
paid to named executive officers and other eligible employees under the bonus
program.

    The Committee has retained authority to grant bonuses apart from the Cash
Bonus Program described above. With respect to executives other than the Chief
Executive Officer, the Committee has authorized the Chief Executive Officer
and/or the President to make recommendations regarding such bonuses. In years in
which there remains unallocated amounts in the bonus pool resulting from
performance in excess of targeted levels, such bonuses may be paid to those
employees who have demonstrated a high level of service, particularly in
projects requiring extraordinary efforts of management and projects which result
in non-budgeted profitable top-line growth.

    The Committee retains discretion to grant bonuses apart from the programs
described above. For 2000, the Committee separately authorized discretionary
bonuses of not more than $7,500 each for certain executives below the level of
the named executives.

STOCK-BASED COMPENSATION

    The long-term stock-based incentive plans offered by the Company are
designed to tie the officers' interests directly to those of the stockholders.
As stated above, the Committee intends that such plans will

                                       13

provide compensation opportunities, resulting from growth in share value, that
are potentially above industry averages. For 2000, such long-term incentives
were provided under the 1995 Long-Term Incentive Plan (the "1995 Plan"),
approved by stockholders in 1995 and amended in 1998. Although the 1995 Plan
authorizes the Stock Plan Committee to use a range of long-term incentive
devices to motivate, attract, and retain high quality executive talent, for 2000
the Stock Plan Committee adhered to the practice of granting stock options based
on the conclusion that options directly link compensation to appreciation in
share value from the date of grant onward, and do so at lower cost than other
types of awards. During 2000, the Committee considered the effects on our
compensation program resulting from the decline in the market price of the
company's stock and difficult business conditions in our industry. The Committee
concluded that previously granted options, which were substantially
out-of-the-money, have relatively little continuing effect as an incentive or
retention vehicle. At the same time, the Committee concluded that repricing
outstanding options would be inappropriate. Applying accepted option valuation
methodologies also influenced the Committee, in that the value of each option
granted while the market price of Common Stock is depressed is generally less
than the per-option value at times of higher prevailing market prices. These
considerations led the Committee to make somewhat larger than usual option
grants in 2000, as compared to prior years. The Stock Plan Committee considered
other factors as well in making grants, including the individual's past and
current performance, compliance with stock ownership requirements under the
Executive Stock Ownership Program, and other subjective factors; the Stock Plan
Committee did not assign any particular weighting to these considerations.

    The Executive Stock Ownership Program, which began in 1995, requires that
certain stock ownership levels be reached and maintained by executive officers
of the Company. Ownership requirements are determined by the executive's base
salary at date of hire or promotion date. Once the initial goal is met after
three years, the executive's ownership requirement is modified annually to tie
it to his/her next year's salary and then-current market prices of Company
stock. Longer time periods are allowed for executives to reach required
ownership levels if the levels rise due to larger stock price movements.
Executives other than the Chief Executive Officer are required to acquire stock
or hold vested stock options equal in value to the executive's targeted salary.
The Chief Executive Officer is required to maintain stock ownership (determined
on the same basis) equal in value to four times his target salary.

OTHER BENEFITS

    As discussed above, the Committee intends that the level of Company benefits
be in line with those of comparable publicly traded companies. Benefits extended
to executives in 2000 were not materially changed from the levels established in
1999

CHIEF EXECUTIVE OFFICER COMPENSATION

    The Committee set the Chief Executive Officer's 2000 base salary at
$655,200, representing no increase over 1999. The considerations affecting the
Committee's determination with respect to the Chief Executive Officer's salary
are discussed above. The Committee authorized an annual bonus of up to 100% of
the CEO's salary based on pre-tax operating income, subject to meeting a
specified earnings per share target. As discussed above, based on performance in
2000 no bonus was paid. In keeping with the Committee's view that a significant
portion of Chief Executive Officer compensation should be tied to the Company's
future performance, stock options provide a component of compensation which
offers above-average compensation opportunities tied to growth in share value.
The Chief Executive Officer was granted options to purchase 365,000 shares in
May 2000 under the 1995 Plan. Such options have a stated term of ten years, and
an exercise price per share equal to 100% of the fair market value per share on
the date of grant. As discussed above, this grant was made by the Stock Plan
Committee based on its consideration of the Chief Executive Officer's past and
current performance and demands upon him, as well as subjective factors, without
assigning a particular weighting to these considerations.

------------------------

(1) Amounts shown include cash compensation earned and received by the named
    executives as well as amounts earned but deferred at the election of those
    officers.

(2) The numbers represent shares underlying options. No stock appreciation
    rights ("SARs") were granted or outstanding during the periods covered by
    the table.

(3) The amounts reflected as compensation to executives resulting from
    split-dollar insurance policies purchased in 1997 are calculated based on
    regulations of the SEC. The regulations require compensation to be
    calculated on the assumption that most of the premiums paid by the Company
    represent a long-term, no-interest loan to the executive. This assumption
    results in high compensation expense being shown in early years of the
    expected life of each policy and lower expense in later years, while in fact
    the cash surrender value of such a policy to the executive is very low in
    the early years and higher in the late years. Moreover, the amounts
    reflected as compensation to the named executives from such policies
    substantially exceed the Company's compensation expense resulting from such
    policies, which for 2000 totaled $426.

(4) This amount includes $7,434 which was contributed by the Company to the
    Company's Profit Sharing/401(k) Plan and Trust (the "401(k) Plan") on behalf
    of Dr. Marlon. The 401(k) Plan is the primary retirement vehicle available
    to the Company's employees. Also included in this amount is $49,884, which
    represents compensation from a split-dollar life insurance policy.

                                       17

(5) This amount includes $7,086, which was contributed by the Company to the
    Company's 401(k) Plan on behalf of Ms. MacDonald, and $69,563, which
    represents compensation from a split-dollar life insurance policy.

(6) This amount includes $6,025, which was contributed by the Company to the
    Company's 401(k) Plan on behalf of Mr. Bunker and $13,464, which represents
    compensation from a split-dollar life insurance policy.

(7) This amount includes $9,586, which was contributed by the Company to the
    Company's 401(k) Plan on behalf of Mr. Howard and $17,931, which represents
    compensation from a split-dollar life insurance policy.

(8) This amount includes $6,773, which was contributed by the Company to the
    Company's 401(k) Plan on behalf of Mr. Collins and $18,012, which represents
    compensation from a split-dollar life insurance policy.

(1) All options were granted at an exercise price equal to the fair market value
    of the Company's Common Stock on the option grant date. The exercise price
    may be paid by the optionee in cash or by check, except that the Stock Plan
    Committee may, in its discretion, allow such payment to be by surrender of
    unrestricted shares of the Company's Common Stock (at their fair market
    value on the date of exercise), or by a combination of cash, check and
    unrestricted shares.

(2) These options were granted on May 17, 2000, and vest and are exercisable at
    the rate of 20% per year starting with the first anniversary date of the
    grant and will expire not later than ten years after grant. All awards were
    non-qualified stock options granted pursuant to the Company's 1995 Long-Term
    Incentive Plan. No stock appreciation rights were granted with the above
    awards. Upon a change of control of the Company, as defined in the 1995
    Plan, the vesting of the options will be automatically accelerated;
    provided, however, that the Stock Plan Committee may exclude a change of
    control transaction from the foregoing provisions and permit the option to
    continue to vest in accordance with its original terms. In addition, the
    options shown above will terminate and may no longer be exercised if the
    respective optionee ceases to be an employee or Director of the Company,
    except for certain post-termination exercise periods in the case of death,
    disability, or other involuntary termination other than termination for
    "cause." The options, together with certain gains realized upon exercise of
    the options during a specified period, will be subject to forfeiture if the
    optionee engages in certain acts in competition with the Company, misuses
    proprietary information of the Company, or fails to

                                       18

    assist the Company in litigation. Cashless withholding to satisfy tax
    obligations may be permitted by the Stock Plan Committee.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT AND CHANGE OF CONTROL
  ARRANGEMENTS

    The Company recently renewed employment agreements with its Chief Executive
Officer (the "CEO") and other executive officers. The term of employment covered
by the agreements is five years for the CEO, and ranges from one to five years
for other executive officers. Under the agreements, an executive may voluntarily
terminate employment upon 60 days' notice. The Company may terminate an
executive's employment, with or without cause, in accordance with the Company's
usual policies and procedures. The agreements provide that, in the event of a
termination by the Company without cause, a severance payment will be paid in
the amount of 24 months' salary to the Chief Executive Officer, and amounts up
to 15 months' salary to other executives. In addition, in the case of any
termination of employment other than for cause, the Company will generally
provide health care benefits for a period equal to the length of the executive's
service or until the executive is eligible for Medicare, whichever occurs first.
The agreements provide that, for senior executives, a disability must continue
for a specified period of time, up to at least 12 months, before the Company may
terminate an executive's employment. In the event of a change in control of the
Company, the Chief Executive Officer will be entitled to terminate employment
and receive a payment equal to four times his salary and target annual
incentive. For executives other than the Chief Executive Officer, if a change in
control is not approved by the Board of Directors, or if a change in control is
approved by the Board but within two years thereafter the executive is
terminated without cause, demoted, provided reduced compensation or required to
relocate, the executive will be entitled to receive a payment equal to a
multiple of salary and target annual incentive compensation. Such multiple will
be approximately three in the case of senior executives, and lower multiples for
less senior executives. In addition, if "golden parachute" excise taxes apply to
compensation paid by the Company, the Company will provide a gross-up payment
sufficient to cause the after-tax value of the compensation and the gross-up
payment to the executive to be the same as if no such excise tax had applied.
The employment agreements contemplate annual adjustments in compensation based
on job duties, performance goals and objectives, and other reasonable standards
deemed appropriate by the

                                       19

Committee. The agreements restrict each executive's use and disclosure of
confidential information, interference with the Company's business
relationships, and competition with the Company, including an agreement that,
for a one-year period following any termination of employment, the executive is
prohibited from working for any competitor which operates in Nevada.

    In February 2001, Ms. MacDonald resigned as President and Chief Operating
Officer. She has agreed, however, to continue as a part-time employee in the
capacity of Chief of Staff. As a result, her employment agreement has been
modified to provide for salary payable at the rate of $222,809 per year, with
eligibility for an annual incentive payment of 100% of salary. Other terms of
her employment agreement are similar to those of senior executives described
above, including participation in compensatory plans for executives, except that
severance payable in connection with a non-approved change of control or a
termination not for cause or constructive termination following an approved
change of control will equal four times base salary and target annual incentive
compensation effective immediately prior to the changes of the new employment
agreement. In connection with the termination of the prior employment agreement,
the Company paid Ms. MacDonald $300,000.

    As described in footnote 3 to the table entitled Option/SAR Grants In Fiscal
Year 2000, under certain circumstances the exercisability of options granted to
named executives is accelerated in the event of certain changes in control of
the Company.

SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

    The Company's Supplemental Executive Retirement Plan (the "Supplemental
Plan"), provides retirement benefits for selected executive officers. Under the
Supplemental Plan, each executive selected for participation generally will be
entitled to receive annual payments, following retirement, disability, or
certain other terminations of employment, for a 15-year period, equal to 3.75%
of his or her "final average compensation" (as defined) for each year of service
credited to the executive up to 20 years, reduced by an amount equal to the
annualized payout over a 15-year period that would be payable to the executive
as a result of Company contributions under the 401(k) Plan and the Deferred
Compensation Plan (but not reduced for social security payments or other
offsets). An executive's right to benefits under the Supplemental Plan vests
when five years of service have been credited or earlier upon the executive's
death or disability or upon occurrence of a change in control (defined in the
same way as under other compensatory plans). Upon the death of the executive,
benefits will be payable for the 15-year period to the executive's beneficiary.
Benefits will begin after retirement at or after age 65, a termination at or
after age 55 if the executive has ten years of credited service, or a
termination due to disability. In the case of other terminations (except a
termination for "cause," as defined) prior to a change in control, benefits will
begin at the later of termination or the date the executive would have completed
ten years of service but for the termination.

    The following table shows the approximate amounts of annual retirement
income that would be payable under the Supplemental Plan to executives covered
by it based on various assumptions as to final average compensation and years of
service, assuming benefits are paid out over 15 years:

                                       20

    Final average compensation generally means the average of the three highest
years of compensation out of the last five years, with compensation being
generally the amounts reported as salary and bonus in the Summary Compensation
Table.

    Each of the executives named in the Summary Compensation Table above have
been selected for participation in the Supplemental Plan. The credited years of
service for such named executives are as follows: Dr. Marlon, 20 years;
Ms. MacDonald, 20 years; Mr. Bunker, 8 years; Mr. Howard, 17 years; and
Mr. Collins, 18 years. As a result of her termination as President in
February 2001, Ms. MacDonald will not thereafter accrue additional years of
service or benefits under the Supplemental Plan, and her benefits under the
Supplemental Plan will be paid out commencing in 2001. An additional year of
service will be credited in the event of a termination within six years after a
change in control, and the year of service for the year of the change in control
will be deemed completed at the time of the change in control. An executive's or
beneficiary's benefits are payable in a lump sum in certain circumstances,
including following a change in control.

    Other executives of the Company participate in the Supplemental Plan. In
addition, there are other executives who participate in the Company's
Supplemental Executive Retirement Plan II ("Plan II"). The terms of Plan II are
substantially the same as those of the Supplemental Plan except that annual
benefits are calculated at a rate reduced by one-third from the level of
benefits under the Supplemental Plan. Thus, the amounts of annual retirement
income shown in the above table, reduced by one-third, represent the benefits
generally available under Plan II.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The members of the Compensation Committee, each of whom is a non-employee
Director, are Messrs. Hartley, Raggio, Ruthe and Watson. The members of the
Compensation sub-committee are Messrs. Hartley, Ruthe and Watson.

    Mr. Raggio is a shareholder of Jones-Vargas, a Nevada law firm which during
2000 rendered legal services to the Company.

DIRECTOR COMPENSATION

    Directors who are not officers or employees of the Company are paid $18,000
per annum, plus a $1,000 meeting fee for meetings attended, including committee
meetings of the Board. This policy applies to Messrs. Raggio, Ruthe, Hartley,
Watson, Luce and Greene.

    The 1995 Non-Employee Directors' Stock Plan, as amended (the "Directors'
Plan"), provides for an automatic grant to each non-employee Director of an
option to purchase 7,500 shares of Common Stock. Such grants are made
automatically on the date on which a person is first elected to the Board of
Directors and on each January 20 thereafter (unless the initial grant occurred
within four months prior to such date). The options' exercise price per share is
equal to the fair market value of a share on the date of grant. Such options
become exercisable as to 20% of the underlying shares on each of the first five
anniversaries of the date of grant, at the date six months prior to the
expiration of a Director's term, if such Director continues to serve through
such date and will reach age 75 before the expiration of the term, or
immediately if the Director ceases to serve due to death or disability, or upon
a change of control more than six months after grant. The options expire at the
earliest of ten years after grant, one year after the optionee ceases to serve
as a Director due to death, disability or retirement or six months after the
optionee ceases to serve as a Director for any other reason (the
post-termination period is extended for up to one year if the optionee dies
during such period). Options not exercisable at or before the time a Director
ceases to be a Director are canceled. The Directors' Plan also permits a
non-employee Director to elect to forego cash fees that are otherwise payable
and receive instead the equivalent value in shares of Common Stock or credits of
"deferred stock" that will be settled at a future date by issuance of Common
Stock.

                                       21

    During 2000, the Company granted to each non-employee director an additional
option to purchase 10,000 shares of Common Stock. These options expire ten years
after grant, with other terms substantially the same as the terms of options
automatically granted under the Directors' Plan, as described above. During
2000, Mr. Ruthe also received $3,700 as Director's fees for his service as
Chairman of the Board of HPN.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    For information concerning Certain Related Transactions with respect to
Mr. Raggio, a Director of the Company, please refer to "Compensation Committee
Interlocks and Insider Participation."

    The Board of Directors has authorized the Company to make certain personal
loans to Dr. Marlon, our Chairman of the Board and Chief Executive Officer.
During 2000, the largest aggregate principal amount of these borrowings and
accrued interest was approximately $5.4 million. At March 31, 2001, the
outstanding principal and accrued interest on these amounts was approximately
$5.5 million. The outstanding balance is due in June 2002. All borrowed amounts
bear interest at a rate equal to the rate at which the Company could have
borrowed funds under its revolving credit facility at the time of the borrowing
plus 10 basis points. The amounts outstanding are collateralized by certain of
Dr. Marlon's assets and rights to compensation from the Company.

ITEM NO. 3--RATIFICATION OF APPOINTMENT OF AUDITORS

APPOINTMENT OF AUDITORS

    The Board of Directors has appointed the firm of Deloitte & Touche LLP,
independent certified public accountants, as auditors of the Company for the
year ending December 31, 2001. Although not required to do so, the Board has
determined that it would be desirable to request ratification of this
appointment by the holders of Common Stock of the Company. If such ratification
is not received, the Board will reconsider the appointment. Representatives of
Deloitte & Touche LLP are expected to be present at the 2001 Annual Meeting,
will have the opportunity to make a statement if they so desire, and are
expected to be available to respond to appropriate questions from stockholders.

    THE BOARD OF DIRECTORS CONSIDERS DELOITTE & TOUCHE LLP TO BE WELL-QUALIFIED
AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR RATIFICATION.

ITEM NO. 4--SHAREHOLDER PROPOSAL

    Management has been advised that the Amalgamated Bank of New York LongView
SmallCap 600 Index Fund (the "Fund"), 11-15 Union Square, New York, NY 10003,
the holder of 21,700 shares of the Company's Common Stock (as of December 6,
2000), intends to submit the following proposal at the Annual Meeting:

    RESOLVED: The shareholders of Sierra Health Services, Inc. (the "Company")
urge the Board of Directors to obtain prior shareholder approval for all future
agreements that provide compensation for senior executives if there is a change
in control of the Company.

                              SUPPORTING STATEMENT

        Sierra Health Services has entered into employment agreements with its
    Chief Executive Officer and several other senior officers, which agreements
    provide these officers with special severance compensation in certain
    situations where there is a change in control of the Company.

                                       22

        These severance agreements, commonly known as "golden parachutes,"
    provide that if the affected officers resign or are terminated under
    circumstances covered by the employment agreement, the CEO shall be entitled
    to receive a multiple of four times his base salary and "target annual
    incentive" bonus; other senior officials are entitled to receive smaller
    multiples of their base salary and target annual incentive bonuses.

        The Company's golden parachute agreements were adopted without the
    approval of shareholders, and we believe that shareholders should be able to
    vote on such agreements in the future, as a means of assessing potential
    conflicts of interest between executives and shareholders.

        In our view, golden parachutes have the potential to create the wrong
    incentives, reduce shareholder value and reward mismanagement. A change in
    control scenario is more likely to occur if executives have managed the
    Company in ways that do not maximize shareholder value, and the existence of
    golden parachutes can allow covered executives to walk away with millions of
    dollars even if shareholder value has suffered during their tenure.

        And the Company's shareholder value has suffered in recent years. As of
    December 2000 the Company's stock was trading at levels not seen in the past
    ten years. Over the past five years, it has also underperformed its peer
    group and the S&P 500 index.

        We believe that shareholders should have the opportunity to review
    golden parachute arrangements in the future.

        We urge you to vote FOR this resolution.

                                   * * * * *

    The Board of Directors opposes this resolution and urges you to vote AGAINST
it.

    The Board and its Compensation Committee, made up entirely of independent
directors, have approved the change-in-control severance arrangements for
executives because we view them as beneficial to the Company. We do not agree
with the proponent of this proposal that such arrangements somehow induce our
executive officers to mismanage the Company.

    We see clear benefits to the Company from severance arrangements that assure
executives that, if employment terminates following a change in control, they
will receive a fair severance package. These benefits to the Company include the
following:

--  Public companies commonly provide change-in-control protections to
    executives, so we include them as part of our competitive compensation
    program in order to attract and retain high quality executives.

--  A change-in-control often results in loss of an executive's job, or a
    reduction in his or her authority. This is a powerful incentive for
    executives to oppose a change-in-control transaction even if it would
    benefit the Company and its stockholders. To mitigate this disincentive, we
    assure executives a fair severance package in the event of termination after
    a change in control.

--  The assurance of fair severance pay also helps maintain stable operations in
    the face of a possible change in control. Executives who have no protections
    would have an incentive to find new employment in the face of a threatened
    change in control, which could disrupt our operations whether or not the
    change in control transaction is completed.

--  An acquiror may want an executive to continue for a period of time after the
    change in control, believing his or her retention would enhance the value of
    the Company. Change in control protections can help to retain an executive
    in this circumstance.

    The proponent of this resolution argues that change-in-control severance
arrangements "create the wrong incentives" and provide rewards to executives
even if they have mismanaged a Company. We do not

                                       23

agree that a change in control is likely only if there has been a failure to
maximize stockholder wealth. As stated above, we want executives to be open to
the possibility of a change in control transaction if that would maximize
stockholder value. The Board, while acknowledging that our stock price
performance has been disappointing over the past few years, strongly rejects the
proponent's insinuation that our change-in-control severance agreements have
contributed to the decline by providing the "wrong incentives" to management.

    Our ability to adopt appropriate severance arrangements, particularly in
response to a potential change in control or in attracting a new executive to
the Company, would be greatly impaired if every such arrangement were subject to
stockholder approval. Obtaining such stockholder approval would add expense as
well, particularly if the requirement for "prior" stockholder approval forced us
to call a special stockholders meeting rather than to wait for the next
regularly scheduled meeting.

    Approval of this shareholder proposal would require that the number of votes
cast in favor of the proposal exceeds the number of votes cast against the
proposal.

    ACCORDINGLY, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE AGAINST
APPROVAL OF THE PROPOSAL TO OBTAIN PRIOR STOCKHOLDER APPROVAL FOR ALL FUTURE
AGREEMENTS THAT PROVIDE COMPENSATION FOR SENIOR EXECUTIVES IF THERE IS A CHANGE
IN CONTROL OF THE COMPANY.

       COMPLIANCE WITH SECTION 16 OF THE SECURITIES EXCHANGE ACT OF 1934

    Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's Directors and executive officers, and persons who beneficially own
more than 10% of the Company's outstanding Common Stock, to file with the SEC
initial reports of beneficial ownership and reports of changes in beneficial
ownership of Common Stock and other equity securities of the Company on Forms 3,
4 and 5, and to furnish the Company with copies of all Section 16(a) forms they
file. With respect to such reports relating to 2000, Mr. Palmer inadvertently
failed to timely file a Form 4 reporting a single open-market purchase, which
was corrected by the filing of a Form 5.

                                       24

                                 OTHER MATTERS

    Except for the stockholder proposal described above and certain stockholder
proposals omitted from these proxy materials pursuant to Rule 14a-8 under the
Securities Exchange Act of 1934, the date 45 days before the anniversary of the
mailing date of the Company's proxy statement for the 2000 Annual Meeting of
Stockholders, the Company had not received notice of any proposal to be

                            AUDIT COMMITTEE CHARTER

    The purpose of this charter is to set forth the guidelines for the
composition, and duties and responsibilities of the Audit Committee of the Board
of Directors of Sierra Health Services, Inc. ("SHS").

I.  AUDIT COMMITTEE PURPOSE

    The Audit Committee is appointed by the Board of Directors to assist the
Board in fulfilling its oversight responsibilities. The Audit Committee's
primary duties and responsibilities are to:

    - Monitor the integrity of the Company's financial reporting process and
      systems of internal controls regarding finance, accounting, and legal
      compliance.

    - Monitor the independence and performance of the Company's independent
      auditors and internal auditing department.

    - Provide an avenue of communication among the independent auditors,
      management, the internal auditing departments and the Board of Directors.

    The Audit Committee has the authority to conduct any investigation
appropriate to fulfilling its responsibilities, and it has direct access to the
independent auditors as well as anyone in the organization. The Audit Committee
has the ability to retain, at the Company's expense, special legal, accounting,
or other consultants or experts it deems necessary in the performance of its
duties.

II. AUDIT COMMITTEE COMPOSITION

    Audit Committee members shall meet the requirements of the New York Stock
Exchange ("NYSE"). The Committee shall be comprised solely of three or more of
the outside directors of SHS. The Chair shall be selected by the members of the
Committee. All members shall be reappointed annually following the Annual
Meeting of Shareholders, each of whom shall be independent nonexecutive
directors, free from any relationship that would interfere with the exercise of
his or her independent judgment. All members of the Committee shall have a basic
understanding of finance and accounting and be able to read and understand
fundamental financial statements, and at least one member of the Committee shall
have accounting or related financial management expertise.

    Audit Committee members shall be appointed by the Board of Directors. If an
Audit Committee Chair is not designated or present, the members of the Committee
may designate a Chair by majority vote of the Committee membership.

III. MEETING SCHEDULE

    The Committee shall meet at least four times per year. If possible, meetings
should generally be scheduled approximately 37 to 42 days after each quarter
end, and 80 to 85 days after year end. This schedule should allow the Committee
to review the Company's internal financial reports (according to Audit Committee
Financial Statement Format) as well as financial reports on Forms 10-Q and 10-K
to the SEC, which are due 45 and 90 days after quarter and year end,
respectively. The meetings should be scheduled to precede Board of Director
meetings to be held on the same day, when possible. The Chair may call special
meetings if circumstances require.

                                       26
