Q65-Q79 — Congenital malformations and deformations of the musculoskeletal system
ICD-10-CM codes Q65-Q79 cover congenital malformations and deformations of the musculoskeletal system, within congenital malformations, deformations and chromosomal abnormalities. The block holds 321 codes across 15 categories, of which 255 are billable and 66 are header codes that cannot be submitted on a claim.
What else to watch in Q65-Q79
- 74 codes are laterality-specific. They come in left and right pairs, and the pair is mutually exclusive on a single site: coding both without a bilateral code is a contradiction a scrubber should catch before the payer does.
- 168 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
