         If the notification relates to a portion of the filing checked above,
identify the Item(s) to which the notification relates:


Part I - Registrant Information


         Full Name of Registrant:  MC Informatics, Inc.
         Former Name if Applicable:  HealthDesk Corporation
         Address of Principal Executive Office:

                  18881 Von Karmen Ave., Suite 100
                  Irvine, CA 92612


Part II - Rules 12b-25(b) and (c)


         If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed. (Check box if appropriate)






[X]      (a) The reasons described in reasonable detail in Part III of this form
         could not be eliminated without unreasonable effort or expense;


[X]      (b) The subject annual report, semi-annual report, transition report on
         Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion thereof will be
         filed on or before the fifteenth calendar day following the prescribed
         due date; or the subject quarterly report or transition report on Form
         10-Q, or portion thereof will be filed on or before the fifth calendar
         day following the prescribed due date; and

[ ]      (c) The accountant's statement or other exhibit required by Rule
         12b-25(c) has been attached if applicable.


Part III - Narrative


         State below in reasonable detail the reasons why Form 10-K and Form
10-KSB, 20-F, 11-K, 10-Q and Form 10-QSB, N-SAR or the transition report or
portion thereof could not be filed within the prescribed time period. (Attach
extra sheets if needed)

         During 1998, HealthDesk Corporation entered into definitive agreements
to sell substantially all of its assets to Patient InfoSystems, Inc. and
thereafter merge with MC Informatics, Inc. On February 26, 1999, HealthDesk
Corporation shareholders approved the sale of assets to Patient InfoSystems and
the merger with MC Informatics, Inc. In connection with the foregoing
transactions, substantially all of the employees, including the entire
accounting staff, are no longer employed by the Company. In addition, the
Company relocated its corporate offices from Berkeley, California to Irvine,
California. Accordingly, new management and accounting staff are in the process
of reconstructing certain financial information to complete the required annual
audit and Form 10-KSB filing. Because of the above, the annual audit and 10-KSB
cannot be filed by March 31, 1999 without unreasonable effort and/or expense.

Part IV - Other Information

         (1) Name and telephone number of person to contact in regard to this

of the Securities Exchange Act of 1934 or Section 30 of the Investment Company
Act of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).

[ ] Yes     [X] No

         (3) Is it anticipated that any significant change in results of
operations from the corresponding period for the last fiscal year will be
reflected by the earnings statements to be included in the subject report or
portion thereof?

[X] Yes     [ ] No

         If so, attach an explanation of the anticipated change, both
narratively and quantitatively, and, if appropriate, state the reasons why a
reasonable estimate of the results cannot be made.
