                        Item 9. Regulation FD Disclosure

This form 8-K is being  furnished  to report  information  pursuant to Item 12 -
Disclosure of Results of Operations and Financial  Condition in accordance  with
interim guidance  provided by the Securities and Exchange  Commission in Release
No. 33-8216 issued March 27, 2003. See Item 12 below.

      Item 12. Disclosure of Results of Operations and Financial Condition

On  April  22,  2003,  Sierra  Health  Services,  Inc.  issued  a press  release
announcing operating results for the quarter ended March 31, 2003. A copy of the
press  release  is  attached  as  Exhibit  99.1 to this  Current  Report  and is
incorporated herein by reference.

                    Item 7. Financial Statements and Exhibits

Exhibits                             Description


99.1                Press Release, dated as of April 22, 2003

All of the  information  furnished in this report and the  accompanying  exhibit
shall not be deemed to be "filed" for  purposes of Section 18 of the  Securities
and Exchange Act of 1934, as amended, and shall not be incorporated by reference
in any filing under the Securities Act of 1933, as amended.

Statements in the press release  referred to above that are not historical facts
are  forward-looking  and based on  management's  projections,  assumptions  and
estimates;  actual results may vary materially.  Forward-looking  statements are
subject to certain  risks and  uncertainties,  which include but are not limited
to: 1)  potential  adverse  changes in  government  regulations,  contracts  and
programs,  including TRICARE,  Medicare,  Medicaid and legislative  proposals to
eliminate  or  reduce  ERISA  pre-emption  of state  laws  that  would  increase
potential  managed care  litigation  exposure;  2)  competitive  forces that may
affect pricing,  enrollment and benefit levels; 3) unpredictable  medical costs,
malpractice  exposure,  reinsurance  costs and inflation;  4) impact of economic
conditions;  5) changes in healthcare and workers' compensation reserves; 6) our
failure to win the  competitive  procurement  for the North Region  TRICARE Next
Generation  contract or obtain an extension of the Medicare Social HMO contract;
and 7) the amount of actual proceeds  realized upon the final disposition of the
workers'  compensation  insurance  operation or the inability to dispose of such
business.  Further factors concerning  financial risks and results are contained
in our Annual  Report on Form 10-K for the year ended  December 31,  2002.  Such
statements  are made  pursuant to the "safe  harbor"  provisions  of the Private
Securities  Litigation  Reform Act of 1995 and identify  important  risk factors
that could cause our actual results to differ materially from those expressed in
any projected, estimated or forward-looking statements relating to Sierra.
