In Congenital malformations and deformations of the musculoskeletal system (Q65-Q79), chapter 17: Congenital Malformations, Deformations and Chromosomal Abnormalities
21 billable codes under Q76: 10 are a CC; none map to an HCC.A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment.

Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
Assign Q00-QA1 codes for documented congenital anomalies or genetic disorders at any age, coding non-inherent manifestations separately and sequencing Z38 first on the birth admission.
