Correspondence Specialists

The Correspondence Specialist Unit (CSU) resolves complex billing issues. TSC agents may refer providers to the CSU for inquiries that require additional research.

Providers may write directly to the CSU for clarification about recurring billing issues that have not been resolved through either the Claims Inquiry Form (CIF) or appeal process and have resulted in claim denials or potential unsatisfactory payments.

When writing to the CSU for assistance, providers should enclose up to three examples of Claim Control Numbers (CCNs) for the billing issue and include as much of the following documentation as possible with the letter of inquiry:

  • Legible claim form
  • Proof of eligibility, if date of service is beyond one year
  • Necessary documentation, operative report, invoice, etc.
  • Copies of all Remittance Advice Details (RADs)
  • Copies of all CIF acknowledgements, response letters
  • Copies of all Appeals acknowledgements, response letters
  • Copies of all dated correspondence from the California MMIS Fiscal Intermediary

  • Note:

    A lack of necessary records may delay research.

CSU responds to providers either in writing or by telephone to clarify billing procedures. Letters to CSU should be addressed as follows:

California MMIS Fiscal Intermediary

P.O. Box 13029
