FOR IMMEDIATE RELEASE


         IDX Systems Corporation Announces Acquisition of ChannelHealth
     Physician connectivity tools improving the healthcare delivery process

Burlington,  VT, April 21, 1999--IDX Systems  Corporation  (Nasdaq:  IDXC) today
announced  that on April 1, 1999 IDX  purchased 80 percent of  ChannelHealth  of
Bedford,  Massachusetts.  IDX paid $6.5  million  in cash for its  interest  and
committed an  additional  $16 million in cash to fund  operations  over the next
three years. IDX has also agreed to pay an additional $3 million,  contingent on
achieving certain performance goals.  ChannelHealth  develops Web-based services
designed to provide  healthcare  consumers with  comprehensive drug information,
extensive disease, health, and wellness information, and e-commerce for ordering
and fulfillment of medical products.  ChannelHealth's Web services,  expected to
be available to  consumers  by midyear,  is designed to enhance the  traditional
physician-patient  and  pharmacy-patient  relationships  by pointcasting  custom
tailored healthcare information and product offerings to patients and physicians
through a secure and confidential private community network.

According to IDX Chief Executive Officer Richard E. Tarrant, "Our Internet track
record began three years ago with the launch of OutReach,  our Web-based product
that  connects  physicians  and  other  healthcare  providers  to data  from IDX
systems.  We are building on this success to improve  healthcare by  integrating
patient access to the healthcare  system through our Web initiative.  We believe
patients  will want to go to their  physicians'  websites to request a scheduled
visit, view lab results, and interact with IDX transaction and clinical systems.
And once online,  we expect that  patients  will demand  information  on medical
conditions,  drugs and  other  health  products.  Through  acquisitions  such as
ChannelHealth,  IDX is  positioned  to push health  information  and  e-commerce
anywhere on the value chain.  With this capability,  IDX expects to continue the
lead in transforming healthcare on the Internet."

David R. Page,  a  pharmacist  and  expert in direct  marketing  for  healthcare
products, founded True Channel Communications in 1996. Mr. Page will remain with
ChannelHealth.  "It is an exciting  opportunity  to be aligned  with a corporate
leader  in the HCIS  industry.  This  acquisition  validates  the  ChannelHealth
solution for physicians,  patients and healthcare  plans," said Page.  "With the
IDX and  ChannelHealth  combination,  we expect  physicians  and  pharmacists to
extend  their   capabilities  for  patient   education  with  online  healthcare
information  in a way that  will be  easily  accessible  and  meaningful  to the
patient."

products,  and  the use of the  Internet  as a  connectivity  tool  for  content
delivery and e-commerce capabilities. With the ChannelHealth acquisition, IDX is
adding a critical building block in the IDX Web strategy.
