What This Code Means

A genetic muscle weakness disorder affecting the hip and shoulder muscles that is inherited in an autosomal dominant pattern, meaning only one copy of the mutated gene is needed to cause the disease.

Coding Tips

• •Verify family history documentation to confirm autosomal dominant inheritance pattern
• •Link to genetic testing results when available to support the specific subtype diagnosis

Clinical Significance

Autosomal dominant limb girdle muscular dystrophy is a group of genetic muscle disorders affecting the proximal hip and shoulder muscles with dominant inheritance pattern. Though generally milder than recessive forms, it causes progressive disability and requires ongoing multidisciplinary care. Specific genetic typing supports accurate prognostication and potential eligibility for gene-targeted therapies.

Documentation Requirements

• ✓Genetic testing confirming autosomal dominant inheritance pattern
• ✓Clinical findings: proximal weakness in hip and shoulder girdle muscles
• ✓Family history consistent with dominant inheritance (affected parent)
• ✓Muscle biopsy findings when available
• ✓Functional status: ambulation, ability to rise from chair, arm elevation
• ✓Provider's explicit diagnosis specifying autosomal dominant limb girdle muscular dystrophy
