ICD-10 Code G71.039 – Limb girdle muscular dystrophy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G71.039 – Limb girdle muscular dystrophy, unspecified
What it is
This code identifies limb-girdle muscular dystrophy when the subtype is not documented. It refers to a hereditary muscle disorder that primarily weakens the shoulder and hip girdle muscles.
Clinical signs
Typical findings include progressive proximal muscle weakness, difficulty rising from a chair, climbing stairs, or lifting the arms. Clinical features vary; refer to documentation.
When to use this code
Use G71.039 when the provider documents limb-girdle muscular dystrophy but does not specify the genetic or clinical subtype. It also fits when the record confirms the diagnosis and no more detailed classification is available. Do not infer a subtype from test results alone.
Do not use for
Do not use this code if the chart identifies a specific limb-girdle muscular dystrophy subtype. Check documentation if the weakness is due to another neuromuscular disorder or if the diagnosis is still uncertain.
Coding tip
Code the highest level of specificity documented, and query for the subtype when the record only says “LGMD.”
