Ladies and Gentlemen:

          We have acted as counsel to Allscripts Healthcare Solutions, Inc., a
Delaware corporation (the "Company"), in connection with the preparation and
filing by the Company of a Registration Statement on Form S-4 (Registration No.
333-49568) (the "Registration Statement") under the Securities Act of 1933, as
amended, relating to certain shares (the "Shares") of the common stock, par
value $.01 per share, of the Company.  The Shares will be issued and sold
pursuant to an Agreement and Plan of Merger (the "Merger Agreement"), dated as
of July 13, 2000, by and among the Company, Allscripts, Inc., Bursar
Acquisition, Inc. ("Bursar"), Bursar Acquisition No. 2 ("Bursar No. 2"), Inc.,
IDX Systems Corporation and Channelhealth Incorporated ("Channelhealth"),
whereby Bursar, a wholly-owned subsidiary of the Company, will merge with and
into the Company and Bursar No. 2, a wholly owned subsidiary of the Company,
will merge with and into Channelhealth by means of the merger described therein
(the "Merger").  Capitalized terms defined in the Merger Agreement and used (but
not otherwise defined) herein are used herein as so defined.

In so acting, we have examined originals or copies (certified or otherwise
identified to our satisfaction) of certain corporate records of the Company,
including its Amended and Restated Certificate of Incorporation, as amended, its
Bylaws, and certain resolutions of the Board of Directors of the Company.  We
have also examined the Registration Statement, together with the exhibits
thereto, and such agreements, documents and other instruments, and such
certificates or comparable documents of public officials and of officers and
representatives of the Company, and have made such inquiries of such officers
and representatives, as we have deemed relevant and necessary as a basis for the
opinions hereinafter set forth.  We have reviewed such questions of law as we
have considered necessary or appropriate for the purposes of this opinion.

          In such examination, we have assumed the genuineness of all
signatures, the legal capacity of all natural persons, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified, conformed or photostatic copies and
the authenticity of the originals of such latter documents.  As to all questions
of fact material to these opinions that have not been independently established,
we have relied upon certificates or comparable documents of officers and
representatives of the Company.

          Based on the foregoing, and subject to the qualifications stated
herein, we are of the opinion that:

          1.  When the conditions to the merger set forth in the Merger
Agreement have been satisfied (including that the Registration Statement has
become effective under the Securities Act of 1933, as amended) and the Merger
has been effected in accordance therewith, the shares of Common Stock issued in
exchange for shares of common stock of Channelhealth pursuant to the Merger
Agreement will be duly authorized, validly issued, fully paid and non-
assessable.

          We hereby consent to the use of this letter as an exhibit to the
Registration Statement and to any and all references to our firm in the Proxy
Statement/Prospectus which is a part of the Registration Statement.


                                        Very truly yours,

                                        Weil, Gotshal & Manges LLP
