Summary
Independence Blue Cross updated MA08.130j to MA08.130k effective 04/20/2026, adding filgrastim-laha (Filkri) to the nonpreferred product list and expanding coverage indications for filgrastim products to align with updated NCCN guidelines for CAR-T therapies, lymphomas, and additional chemotherapy regimens. Billing teams must implement product preference rules and ensure claims use appropriate HCPCS codes, particularly the new Q5172 code for filgrastim-laha.
Action Required
REQUIREMENTS:
- By April 20, 2026: Billing team must update billing system to enforce preferred product rules: filgrastim-sndz (Zarxio) and filgrastim-aafi (Nivestym) are preferred; all other filgrastim products including newly added filgrastim-laha (Filkri) are nonpreferred and require prior authorization documentation of contraindication, intolerance, or inadequate response to preferred products.
- By April 20, 2026: Update claims processing logic to map filgrastim-laha claims to HCPCS code Q5172 (or C9399/J3590 as applicable). Ensure billing software recognizes Q5172 as a valid but nonpreferred product code.
- Before April 20, 2026: Train billing and prior authorization staff on expanded coverage indications including CAR-T cell therapies, lifileucel (Amtagvi), pediatric Hodgkin lymphoma, Burkitt lymphoma, diffuse large B-cell lymphoma, and updated chemotherapy regimens (Melphalan PHP, DCEP, FLOT, docetaxel, FOLFIRINOX).
- Before April 20, 2026: Update provider documentation templates and prior authorization request forms to align with new NCCN-recommended indications to support medical necessity claims.
- Immediate ongoing: For any filgrastim-laha (Filkri) claims received: Verify prior authorization documentation; if unavailable or insufficient, deny claim and notify provider that nonpreferred product requires documented contraindication/intolerance to preferred products or prior failed therapy.
- Failure to implement preference rules and prior authorization requirements will result in claim denials and member cost-sharing issues.
