Summary
Independence Blue Cross reissued Policy 09.00.10aa with CPT code updates effective 01/01/2026. Three new CPT codes (77436, 77437, 77439) were added as experimental/investigational for brachytherapy procedures, and obsolete CPT code 0394T was removed. No changes to coverage criteria or medical necessity guidelines occurred.
Action Required
By 01/01/2026: Billing team must update billing software and claims submission systems to remove terminated CPT code 0394T from all brachytherapy-related billing templates and encounter forms. Simultaneously add new CPT codes 77436, 77437, and 77439 to system with experimental/investigational designation, ensuring these codes require documentation of medical necessity per policy guidelines before submission. Update internal code lists and provider education materials to reflect these changes. Do NOT bill 0394T on or after 01/01/2026 as it is no longer valid; claims submitted with this code will be denied. Verify individual member benefits remain applicable only for Independence Administrators claims and groups not enrolled in UM vendor programs per policy restrictions.
