FOR IMMEDIATE RELEASE


                        IDX SYSTEMS CORPORATION ANNOUNCES
                        PRELIMINARY FIRST QUARTER RESULTS


BURLINGTON,  VT,  March  5,  1999  -- IDX  Systems  Corporation  (Nasdaq:  IDXC)
announced  today that based on  currently  available  information,  the  Company
expects sales for the first quarter  ending March 31, 1999 to be in the range of
$60 to $65  million.  Sales in this  range are  expected  to result in a loss of
($0.22)  -  ($0.28)  per  share  for the  quarter,  versus  analysts'  consensus
estimates  of $.35 per share.  The after tax loss for the quarter is expected to
be ($5) - ($7) million.

"We believe the primary factor in the sales shortfall is the unexpected deferral
of  purchasing  decisions  by our  customers  and  prospects,"  said  Richard E.
Tarrant,  IDX Chief  Executive  Officer.  "Although our projected  first quarter
performance  is  well  below  expectation,  we  believe  that  our  business  is
fundamentally sound. Based on the information available,  we expect to return to
profitability  in the second  quarter.  The contracts that have been delayed are
still in the pipeline. IDX has a well-established  customer base, a proven track
record and functionally rich, integrated products and services. We are committed
to a strategy of combining  enterprise  software with the advantages of Internet
technology, which positions the Company for future growth."

The Company plans to announce first quarter results in late April 1999.
