Summary
Independence Blue Cross reissued Policy 11.14.01i on mentoplasty/genioplasty with no material coverage changes. However, six ICD-10 diagnosis codes (Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, Q75.029) were updated for code accuracy effective 10/01/2025. The coverage policy remains unchanged: procedures are cosmetic exclusions unless medically necessary for specific conditions (craniofacial deformities, trauma, OSA, systemic bone disorders, etc.).
Action Required
By October 1, 2025: Billing team must update ICD-10 code mappings in billing software to reflect corrected descriptions for craniosynostosis codes (Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, Q75.029). Update the code reference lists to reflect changes from 'unspecified' to 'unspecified type' where applicable. No coverage policy changes are required. Verify that mentoplasty/genioplasty claims (CPT 21120, 21121, 21122, 21123, 21125, 21127) continue to require medical necessity documentation as outlined in the policy. No claims will be affected by this code update as the coverage rules remain identical.
