ICD-10 Code G71.034 – Limb girdle muscular dystrophy due to sarcoglycan dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G71.034 – Limb girdle muscular dystrophy due to sarcoglycan dysfunction
What it is
This code identifies a limb-girdle muscular dystrophy caused by sarcoglycan dysfunction, a hereditary disorder that weakens the muscles around the shoulders and hips. It is used when the diagnosis specifically links the dystrophy to sarcoglycan abnormality.
Clinical signs
Typical findings include progressive proximal muscle weakness, difficulty climbing stairs, rising from a chair, or lifting the arms. Clinical features vary; refer to documentation for the specific subtype and supporting genetic or neuromuscular findings.
When to use this code
Use this code when the provider documents limb-girdle muscular dystrophy due to sarcoglycan dysfunction, including a confirmed genetic diagnosis or a clearly stated clinical diagnosis. Apply it when the record identifies sarcoglycan involvement rather than a nonspecific muscular dystrophy. Check documentation if the etiology is not explicit.
Do not use for
Do not use this code for unspecified limb-girdle muscular dystrophy, other muscular dystrophy types, or weakness without a documented dystrophic diagnosis. Do not assign it when sarcoglycan dysfunction is not stated or supported in the record.
Coding tip
Code the most specific documented muscular dystrophy subtype and confirm the sarcoglycan cause before assigning G71.034.
