Medi-Cal Provider Identification Number or PIN

We use the Medi-Cal PIN number to check patient eligibility and submit claims through Medical.  

1. What is the PIN used for?

The Provider Identification Number (PIN) is the additional validation of an enrolled provider’s identity that is used when a provider conducts business transactions with the Medi-Cal program and the fiscal intermediary, Xerox State Healthcare, LLC (Xerox). Some examples of transactions requiring use of the PIN would include recipient eligibility verification and submission of a Computer Media Claims (CMC) Agreement to get a submitter ID for electronic billing. 

2. What is the difference between a PIN and a Submitter ID? 

The PIN is the secret code that is used as validation of an enrolled provider’s identity whenever the provider needs to access and transmit information to and from the Medi-Cal program. A Submitter ID is an additional identifier number used specifically for the electronic claims submission process.

3. How do I find out my PIN?

All inquiries about PIN, billing, claims, POS devices and AEVS number issues should be directed to the Telephone Service Center (TSC) at (800) 541-5555 or the POS Help Desk at (800) 427-1295.
