                        Item 9. Regulation FD Disclosure

On Tuesday, February 25, 2003, Sierra Health Services, Inc., or Sierra, issued a
press release announcing  pricing of $100 million aggregate  principal amount of
its 2.25%  senior  convertible  debentures.  The  company  has also  granted the
initial  purchasers  an option  to  purchase  up to an  additional  $15  million
aggregate principal amount of debentures.  A copy of that press release is filed
as Exhibit 99 to this report and incorporated herein by reference.

Item 9.  Regulation FD Disclosure

Exhibits                                        Description

99                                 Press Release Dated February 25, 2003

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;  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, 2001.  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.
