On Wednesday, February 19, 2003, Sierra Health Services, Inc., or Sierra, issued

Item 9.  Regulation FD Disclosure

Exhibits                           Description


99                     Press Release Dated February 19, 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; and 6)
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.
