What This Code Means
Q65 is the ICD-10-CM diagnosis code for congenital deformities of hip. Q65 sits in the ICD-10-CM chapter for congenital malformations, deformations and chromosomal abnormalities (q00-qa0), within the section covering congenital malformations and deformations of the musculoskeletal system (q65-q79).
Header codes like Q65 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for Q65 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
