Summary
Effective September 1, 2026, Anthem Blue Cross (California) will enforce stricter outpatient facility coding validation requiring that claims billed with specific revenue codes (0278, 0636, 0760, 0761, 0762, 0769) must include matching HCPCS or CPT codes. Claims with mismatched revenue and procedure codes will be rejected and must be corrected and resubmitted before reimbursement is issued.
Action Required
By August 31, 2026: Billing team must implement validation controls in billing software to ensure all outpatient facility claims using revenue codes 0278, 0636, 0760, 0761, 0762, or 0769 include appropriate HCPCS or CPT codes. Providers and coders must review CPT coding guidelines and EncoderPro resources to identify correct code pairings for each revenue code. Update claim scrubbing protocols to flag mismatched revenue/procedure code combinations before submission. Communicate requirements to all clinical and billing staff. Failure to comply will result in claim denials and resubmission delays. Establish process for claim disputes via Anthem provider manual if claims are processed incorrectly.
