Claims Information


Submitting Claims

Contra Costa Health Plan (CCHP) uses Availity as our clearinghouse. You must register with Availity in order to submit EDI claims to CCHP. You may begin your registration process here. Please see below for CCHP payer IDs:

  • Contra Costa Health Plan - Payer ID: CCHS
  • Contra Costa Behavioral Health Plan - Payer ID: CCMHP

You may also sign up for CCHP’s ccLink Provider Portal where you can enter and submit claims directly to CCHP. To sign up, please visit cchealth.org/healthplan/providers/, complete the ccLink Provider Portal Access Agreement form, and email it the CCHPportalsupport@cchealth.org. If you have already signed up for ccLink Provider Portal access, please reference the website for instructions regarding submitting claims.

If you must submit a paper claim, please mail your completed claim form along with all required supporting documents to:

  • For CCHP Medical Claims, please mail your paper claims to: P.O. Box 5122, Lake Forest, CA 92609
  • For Behavioral Health Claims, please mail your paper claims to: P.O. Box 5143, Lake Forest, CA 92609

CCHP continues to offer electronic payments to providers. To register, please submit your request to EDIsupport@cchealth.org. To receive a RA (Remittance Advice) electronically, please sign up for our provider portal based on the instruction above.

If you are a non-contracting provider and have never submitted a claim to CCHP or within the last 2 years, you must submit a current W9 to ARsupport@cchealth.org for IRS verification through the County Auditor’s office. If you do not submit a W9 before submitting claims, your claims will not be processed until we receive a W9. As a courtesy, CCHP may reach out to you to request a W9. However, if a W9 is not received within 14 calendar days, your claims will be voided and you must resubmit your claims to be processed.
