Effective May 29, 2026, Medi-Cal Rx will be implementing the following changes to the current Medicare coordination of benefits (COB) claims processed by pharmacies:

  • Medi-Cal Rx will no longer accept the Other Coverage Code (OCC) of 3 – Other Coverage Exist Claim Not Covered when Medicare Part D has denied the claim with Reject Code A5 – Not Covered Under Part D Law or Reject Code 65 – Patient is Not Covered.

Claims submitted with OCC of 3 will start denying with Reject Code 13 – M/I Other Coverage Code with the message of “Member is Medicare Part D eligible. Submit claim to member’s Medicare Plan. Part D copays and deductibles are not covered.”

  • Future change, effective date yet to be determined: For all Medicare COB claims, Medi-Cal Rx will implement a Benefit Stage Qualifier (BSQ) value in the NCPDP field 393-MV. Claims without the BSQ value will be denied along with the message of “Benefit Stage Qualifier value not submitted.”
