Summary
Independence Blue Cross reissued MA11.080c mentoplasty/genioplasty policy on 03/04/2026 with no substantive coverage changes, but updated ICD-10 diagnosis codes for craniosynostosis conditions (Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, Q75.029) effective 10/01/2025. Billing teams must update systems to reflect the revised ICD-10 code descriptions to ensure claims process correctly without denials.
Action Required
By 10/01/2025: Billing team must update diagnosis code mapping in billing software to reflect revised ICD-10 code descriptions for Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, and Q75.029 (replacing 'unspecified' or 'unilateral' language with updated terminology). Notify providers and update any internal coding guides or templates. Verify that claims submitted on or after 10/01/2025 with old code descriptions will not process; claims submitted after this date must use the new code language to avoid rejection or denial. Conduct system testing to ensure the coding updates are properly reflected before the effective date.
