September 24, 2012

If a submitter sending Computer Media Claims (CMC) transactions in either the ASC X12N 4010A1 or NCPDP 5.1/1.1 formats has not yet received a letter announcing the new December 31, 2012 end-date for accepting these formats, Medi-Cal may not have their current mailing address. Submitters who have not received this letter should contact the CMC Helpdesk to update their mailing address. Submitters can reach the CMC Helpdesk by calling the Telephone Service Center (TSC) at 1-800-541-5555, select option 4 for the Technical Help Desk, followed by option 2 for CMC.

HIPAA 4010A1 Submission Instructions Removed from Provider Manual

Updated September 19, 2012
Originally Published June 16, 2012

Update: December 31, 2012, has now been announced as the last day that the 4010A1 and NCPDP 5.1/1.1 formats will be accepted.

Beginning June 25, 2012, the new HIPAA 5010 transaction standards will be implemented. However, providers who choose not to transition to submit 5010 transactions may continue to submit claims using the 4010A1 standards, as they will continue to be accepted after June 25, 2012. The Medi-Cal provider manuals were assessed to see if they contained significant billing instructions for providers to continue submitting claims in the 4010A1 format. Most updates to billing instructions were considered transparent. For example:

  • HIPAA 4010A1 changed to HIPAA 5010
  • NCPDP telecommunication standard 5.1 changed to NCPCP D.0
  • NCPDP telecommunication standard 1.1 changed to NCPDP 1.2
  • Transaction and companion guide titles were updated

However, one manual page contained more complex information about the proper ANSI ASC X12N version to use. That information, from Part 1 Medi-Cal provider manual, CMC Enrollment section, page three, is captured below:

4010 text was: New 5010 text is:
Professional version (claim types 05 and 07) 004010X098A1 Professional version (claim types 05 and 07) 005010X222A1
Institutional version (claim types 02, 03 and 04) 004010X096A1 Institutional version (claim types 02, 03 and 04) 005010X223A2
