ICD-10 Code G71.01 – Duchenne or Becker Muscular Dystrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G71.01 – Duchenne or Becker muscular dystrophy
What it is
G71.01 identifies Duchenne or Becker muscular dystrophy, inherited disorders that cause progressive muscle weakness and degeneration. Use it when documentation names either condition specifically.
Clinical signs
Typical findings include progressive proximal muscle weakness, difficulty rising, frequent falls, and calf pseudohypertrophy. Clinical features vary; refer to documentation.
When to use this code
Use G71.01 when the provider documents Duchenne muscular dystrophy, Becker muscular dystrophy, or both together. It also fits encounters for evaluation, follow-up, or complication assessment when the diagnosis is established. If the record only says “muscular dystrophy,” check documentation for the exact type.
Do not use for
Do not use this code for unspecified muscular dystrophy or other neuromuscular disorders. Check documentation if the note does not clearly distinguish Duchenne or Becker disease.
Coding tip
Code the named diagnosis exactly as documented and confirm whether the record specifies Duchenne, Becker, or an unspecified dystrophy.
