What This Code Means
G73.7 is the ICD-10-CM diagnosis code for myopathy in diseases classified elsewhere. Muscle weakness or disease that develops as a result of another medical condition classified elsewhere in the ICD-10 system. G73.7 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering diseases of myoneural junction and muscle (g70-g73).
G73.7 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Always code the underlying disease first, then use G73.7 as a secondary code to indicate the myopathy is a manifestation of that disease.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G73.7 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
