Summary

Anthem Blue Cross Medi-Cal has updated 23 medical policies and clinical utilization management guidelines effective December 18, 2026, affecting prior authorization requirements, coverage criteria, and medical necessity determinations for procedures ranging from cardiac interventions to diabetic devices. Several policies have changed from "investigational" or "revised" status, potentially affecting coverage for services previously considered medically necessary. The billing team must review each guideline to identify which procedures now require prior authorization or have new documentation requirements.

Action Required

Before Dec 18, 2026
DEADLINE: By December 18, 2026, billing team must complete the following actions: (1) Access Anthem's Medical Policies and Clinical UM Guidelines website and download full text for all 23 updated policies listed (SURG.00011, SURG.00032, SURG.00121, TRANS.00008, CG-DME-42, CG-DME-44, CG-DME-50, CG-LAB-21, CG-LAB-37, CG-LAB-38, CG-MED-101, CG-MED-40, CG-MED-68, CG-OR-PR-02, CG-SURG-106, CG-SURG-126, CG-SURG-127, CG-SURG-131, CG-SURG-132, CG-SURG-133, CG-SURG-90, CG-TRANS-04); (2) Map each policy revision to specific CPT/HCPCS codes used in your practice by reviewing the full policy documents; (3) Identify which policies changed coverage status (particularly those marked "Revised" that may now require prior authorization or deny previously covered services); (4) Update billing software and encounter templates to reflect new prior authorization requirements; (5) Communicate changes to all providers and clinical staff, particularly for cardiac procedures, transplantation, diabetes management devices, and wound care products; (6) For policies marked "Conversion," verify whether these represent new coverage classifications affecting claim submission; (7) Monitor for claim denials after December 18, 2026, and be prepared to educate providers on new medical necessity criteria. Special attention required for revised policies affecting high-volume services (Continuous Glucose Monitoring, Automated Insulin Delivery Systems, Cardiac Monitors, Knee Braces) as these may significantly impact billing workflows. Failure to obtain required prior authorizations will result in claim denials.
