By December 31, 2026: Billing team must complete the following actions: (1) Verify that your organization is enrolled in Medi-Cal FFS through DHCS Provider Enrollment Division (PED) via PAVE; if not enrolled, submit enrollment application immediately to meet the January 1, 2027 deadline. (2) Update billing system configuration to process Medi-Cal FFS claims for transitioned members instead of managed care claims; configure system to use FFS billing requirements and billing codes. (3) Audit and update all billing workflows, encounter forms, and prior authorization procedures to reflect FFS requirements rather than managed care plan requirements. (4) Train billing staff on Medi-Cal FFS billing processes, including electronic and paper claim submission, Treatment Authorization Request (TAR) and eTAR procedures, and FFS rate schedules. (5) Establish care coordination handoff procedures with colleagues to ensure continuity of care; coordinate member records transfer. (6) Update member-facing materials and notifications to inform patients of the transition effective January 1, 2027. (7) Configure billing system to bill eligible care management services using specified FFS CPT and HCPCS codes (98960-98962, G0019, G0022, 99424-99427, 99490-99491, 99437, 99439, G0506, 99366, 99368, G9012, 99484, 99492-99494, T1017, and CPSP codes) for reimbursement. Consequences: Failure to enroll in Medi-Cal FFS will result in claim denials and loss of reimbursement for services to transitioned members. Incorrect billing codes or non-compliance with FFS requirements will result in claim rejections.
