CMC Submission Instructions

CMC Claims Submission on the Internet

Submitters can access the website and start submitting their claims, view submissions, acquire Claim Control Numbers (CCNs) and verify receipt of transmissions all on the Internet. For detailed instructions about how to use these features, see below.

For more information regarding CMC, please refer to the Medi-Cal Computer Media Claims (CMC) Billing and Technical Manual. If you have any questions regarding the instructions below, please call the Telephone Service Center (TSC) at 1-800-541-5555 and select the option for POS, Internet, LSRS and CMC inquiries.

• Click either the "Transaction Services" or "Login" link from the Medi-Cal home page.
• Enter your submitter ID and password. Your submitter ID must be prefixed with "CMCSUB" and the password is the same password you use for CMC dial-up access. Click "Submit."
• The "Transaction Services" menu will appear. You may click either "CMC Uploads" or "Perform Computer Media Claims Data Uploads."
• You can either enter the location and name of the file that you want to send or click "Browse" to locate the file on your PC or network that you want to send.
• Once you have located the file, click "Upload File." (Note: It is recommended that you zip files prior to uploading so that upload times are reduced.) The maximum file size for all files regardless of whether or not they are zipped is 2 megabytes.
• After a few moments, depending on the size of the file, a confirmation page will appear. If the upload was successful, a "Volser Number" will be displayed that may be used to check the status of your transmission. Volser details may not be available for up to 24 hours after the submission is uploaded, and details are available for approximately 30 days.

CMC Submission Inquiry on the Internet

The new "CMC Submission Inquiry" link on the Medi-Cal website offers submitters the option to check CMC submission status. Submitters can check to see if their batch was deleted, had a partial release or full release. For those batches that are not released, information will be available regarding batch errors, as well as how many provider numbers and/or claims were impacted. For the released batches, submitters will be given the range of Claim Control Numbers (CCNs) assigned to each provider in the batch. These CCNs will assist providers attempting to check the status of their individual claims. For detailed instructions about how to use these features, see below.

If you have any questions regarding the instructions below, please call the Telephone Service Center (TSC) at 1-800-541-5555 and select the option for POS, Internet, LSRS and CMC inquiries.
