INDEPENDENT AUDITORS' REPORT

To the Trustees and Participants of
Sierra Health Automatic Retirement Plan

We have audited the accompanying statements of net assets available for benefits
of Sierra Health Automatic  Retirement Plan (the "Plan") as of December 30, 2002
and 2001,  and the related  statements  of changes in net assets  available  for
benefits  for  the  years  then  ended.  These  financial   statements  are  the
responsibility  of the Plan's  management.  Our  responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our  opinion,  such  financial  statements  present  fairly,  in all material
respects, the net assets available for benefits of the Plan at December 30, 2002
and 2001,  and the changes in net assets  available  for  benefits for the years
then ended, in conformity with accounting  principles  generally accepted in the
United States of America.

Our audits  were  conducted  for the  purpose of forming an opinion on the basic
financial  statements taken as a whole. The supplemental  schedule listed in the
Table of Contents is presented for the purpose of additional analysis and is not
a  required  part  of the  basic  financial  statements,  but  is  supplementary
information  required by the  Department  of Labor's Rules and  Regulations  for
Reporting and Disclosure  under the Employee  Retirement  Income Security Act of
1974. The schedule is the responsibility of the Plan's management. Such schedule
has been subjected to the auditing  procedures applied in our audit of the basic
2002 financial statements and, in our opinion, is fairly stated in all material
respects  when  considered  in relation to the basic 2002  financial  statements
taken as a whole.

                   SIERRA HEALTH AUTOMATIC RETIREMENT PLAN

                        Notes to Financial Statements


NOTE 1. PLAN DESCRIPTION

General  Description - The Sierra Health Automatic  Retirement Plan (the "Plan")
is a qualified,  defined  contribution  profit  sharing/401(k)  plan  sponsored,
managed and  administered  by Sierra  Health  Services,  Inc.  (the  "Company").
Prudential  Financial  serves as trustee of the Plan. The Plan is subject to the
provisions of the Employee  Retirement Income Security Act of 1974 ("ERISA").  A
brief description of certain Plan provisions, as amended, follows.  Participants
should  refer to the Plan  agreement  for a complete  description  of the Plan's
provisions.

Contributions - For 2002,  participants may contribute up to 15% of their annual
compensation.   The  Company  makes   matching   contributions   of  100%  of  a
participant's  contribution  up to a maximum of 3% of the  participant's  annual
compensation.  Participant  contributions  above  3% but  not  exceeding  9% are
matched  50%  by  the  Company.  The  maximum  Company  contribution  is 6% of a
participant's  annual compensation.  Participant and employer  contributions are
subject  to  Internal  Revenue  Service  ("IRS")  limits.  Company  matches  are
invested,  based on  participant  selections,  into the common trust  funds.  In
accordance with the Economic Growth and Tax Relief  Reconciliation  Act of 2001,
employees  age  50 and  older  are  permitted  to  make  additional  "catch  up"
contributions not to exceed $1,000. The "catch up" contributions are not matched
by the employer.

Vesting - Participants are immediately  vested in their voluntary  contributions
and earnings  thereon.  Participants are also immediately  vested in the Company
contribution  made  on  their  behalf  up  to  4% of  the  participant's  annual
compensation.  The  remaining  Company  contribution  vests  based  on  years of
service--one-third per year of service--and is fully vested after three years of
service with the Company. If a participant becomes permanently  disabled,  their
account is 100% vested without regard to years of service.

Eligibility  -  All  employees  of  the  Company  not  covered  by a  collective
bargaining  agreement become  participants in the Plan after they have completed
one year of service and are age twenty-one or older.  The Plan defines a year of
service as one in which the employee works at least 1,000 hours.

Participant  Accounts  -  Each  participant's   account  is  credited  with  the
participant's contribution,  the Company's matching contribution and allocations
of Plan earnings.

Payment of Benefits - Upon termination of employment,  participants may elect to
receive a  lump-sum  payment of their  vested  account  balance,  one of several
annuity  payment  options or may  transfer  their  vested  account  balance to a
tax-deferred account.

Termination  of Plan - Although the Company has not  indicated  any intention to
terminate the Plan, or  contributions  thereto,  it may do so at any time.  Upon
termination or partial termination,  each participant's account will become 100%
vested.

Income Taxes - In November  1995,  the Plan  received  its latest  determination
letter from the IRS stating that the Plan, as then  designed,  was in compliance
with the applicable  requirements of the Internal  Revenue Code ("IRC") and thus
exempt  from  income  taxes.  The Plan  has been  amended  since  receiving  the
determination letter.  However, the Plan administrator believes that the Plan is
currently  designed  and  being  operated  in  compliance  with  the  applicable
requirements  of the IRC. No provision for income taxes has been included in the
financial statements.

Administrative Expenses - Administrative expenses of the Plan are paid by either
the Plan or the Plan's  sponsor,  as provided in the Plan  Document.  Total Plan
expenses  for 2002 and 2001 were $51,905 and  $48,811,  respectively,  of which,
$43,130 and $42,500 were paid by the Plan's sponsor, respectively.

Investment in Company Stock - Investments in Company common stock are limited to
30 percent of  employee  elected  deferrals  and  unlimited  on  employer  match
amounts.

Forfeitures - Forfeited accrued benefits may be used to pay expenses incurred in
the basic  administration  of the Plan or to reduce employer  contributions.  In
2001, the Company used  forfeitures in the amount of $90,590 to reduce  employer
contributions.  In 2002,  the  Company  did not use any  forfeitures  to  reduce
employer  contributions.


NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting - The Plan's  financial  statements  are prepared  using the
accrual method of accounting and conform to the American  Institute of Certified
Public  Accountants'  accounting and auditing guide,  Audits of Employee Benefit
Plans.  Accordingly,  income is recorded in the period  earned,  expenses in the
period incurred and the purchase and sale of investments as of the trade date.

Use of Estimates - The  preparation of financial  statements in conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates and assumptions  that affect the reported
amounts of net assets available for benefits and changes therein. Actual results
could  differ  from  those  estimates.  The  Plan  utilizes  various  investment
instruments.  Investment  securities,  in general, are exposed to various risks,
such as interest rate, credit,  and overall market volatility.  Due to the level
of risk associated with certain investment securities, it is reasonably possible
that changes in the values of investment  securities will occur in the near term
and that such  changes  could  materially  affect the  amounts  reported  in the
statements of net assets available for plan benefits.

Investments - Investments are stated at approximate  fair market value. The fair
market value of equity and fixed income  securities  is  determined  principally
from quoted market prices.  The fair market value of common trust funds is based
on the Plan's allocable interest in the fair market value of securities in those
funds.  The fair value of Company  stock is dictated by the daily value from the
New York Stock  Exchange.  The fair market  value of the  investment  in limited
partnerships is based on third-party appraisals. Participant loans are valued at
cost plus accrued interest,  which approximates fair value. Unrealized gains and
losses are  recorded in the period in which they  occur.  All assets are held by
trustees of the Plan.  The Company  match is made in cash and is invested  based
upon employee selections.

Reclassifications  -  Certain  reclassifications  have  been  made  to the  2001
financial statements in order to conform to the 2002 presentation.
