Summary
Independence Blue Cross reissued MA11.080c (Mentoplasty or Genioplasty) with ICD-10 code description updates only—no coverage policy changes. Six craniosynostosis codes (Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, Q75.029) have revised descriptions for clarity. Medical necessity criteria and covered conditions remain unchanged.
Action Required
Before October 1, 2025: Billing team must update ICD-10 code descriptions in billing software for codes Q75.001, Q75.002, Q75.009, Q75.021, Q75.022, and Q75.029 to reflect the revised wording (remove 'unspecified' modifiers and align with updated nomenclature). No coverage policy changes require action. Verify that all mentoplasty/genioplasty claims (CPT 21120-21127) include appropriate medical necessity documentation supporting one of the covered conditions listed in the policy. No immediate workflow changes needed, but ensure coding accuracy for compliance with the reissued descriptors.
