​​​​​​​​​​​​​​​​​​​​​Billing for Services FAQs

1. When can providers start billing​ fo​r services?

After an application has been approved, Medi-Cal providers receive a Welcome Letter and package from Xerox State Healthcare, LLC (Xerox), which contains billing information. Usually within 2-3 weeks after receiving the Welcome Letter and package, the provider receives a separate notification from Xerox with their Provider Identification Number (PIN). Once the provider has received their PIN, they can begin verifying eligibility of their Medi-Cal patients and begin their billing process.

NOTE: Prospective Medi-Cal providers must apply for and be enrolled in the Medi-Cal program and agree to conditions of participation before claim submission or payment can be made for services furnished to Medi-Cal recipients. Prior to approval of the application, an applicant’s decision to see Medi-Cal patients is at their own personal risk for payment.

2. Who bills Medi-Cal for the services o​f rendering provider​​s and locum tenens physicians?

Rendering providers cannot bill directly; it is the group entity that bills Medi-Cal for the services rendered by the providers enrolled in their group. In reimbursement for locum tenens/reciprocal billing, the recipient’s regular physician may submit the claim and receive payment for covered Medicaid services (including emergency visits and related services) provided by a locum tenens physician who is not an employee of the regular physician.

3. Where can providers find answers to ot​her billing questions?

For assistance with billing and claims, please contact the Telephone Service Center at (800) 541-5555 (outside of California, please call 916-636-1980) or online at "Contact Medi-Cal." For the most current information about billing and claims submission, refer to the "Medi-Cal Newsroom" area on the Medi-Cal home page.

4. Who do providers contact when payments (warrants) for billed ​​services are not received? 

If a provider is not receiving payment (warrants) for services that have been billed to the Medi-Cal program, a provider may need to request a change of pay-to address on file with DHCS. Providers are required to notify DHCS within 35 days of the date of a change to the business, and/or pay-to address. To access the correct form, go to the Provider Enrollment page on the Medi-Cal Web site at www.medi-cal.ca.gov and click on Application Forms by Form Name and Number. When the address change has been made, providers will be instructed b​y Provider Enrollment Division about how to request payments be re-issued. Providers also may contact Provider Enrollment Division, Returned Warrant Unit, at (916) 319-8413, or via email at pedretwarr@dhcs.ca.gov.
