ICD-10 Code G71.00 – Muscular dystrophy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G71.00 – Muscular dystrophy, unspecified
What it is
G71.00 identifies muscular dystrophy when the specific type is not documented. Use it for a hereditary or acquired muscle disorder marked by progressive muscle weakness, but only when the record does not name a more specific dystrophy.
Clinical signs
Typical findings include slowly progressive weakness, difficulty walking, frequent falls, and muscle wasting. Clinical features vary; refer to documentation for the exact pattern, distribution, and any confirmed subtype.
When to use this code
Use this code when the provider documents muscular dystrophy without naming Duchenne, Becker, limb-girdle, or another specific form. It also fits when the chart confirms dystrophy but the subtype is still pending or unclear. You should code to the highest documented specificity.
Do not use for
Do not use G71.00 for nonspecific muscle weakness, myopathy, or neurologic weakness without a documented muscular dystrophy diagnosis. If a specific dystrophy is named, report that code instead.
Coding tip
Check the assessment, problem list, and pathology or genetics notes for a named subtype before defaulting to the unspecified code.
