G71.20 — Congenital myopathy, unspecified
Is G71.20 billable?
Yes, but G71.20 is an unspecified code. G71.20 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, G71.20 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting G71.20 — the more specific alternatives are listed below.

Which MS-DRGs does G71.20 group to?

- 092Other Disorders of Nervous System with CCmedical
- 093Other Disorders of Nervous System without CC/MCCmedical
As a secondary diagnosis, G71.20 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
