Short answer · Medically reviewed summary · Last updated: 2026-04-07
TL;DR: Limb-girdle muscular dystrophy (LGMD) is currently classified under the ICD-10 code G71.02. In the older ICD-9-CM classification system, Limb-girdle muscular dystrophy was categorized under the code 359.1. What exactly is Limb-girdle muscular dystrophy? Limb-girdle muscular dystrophy represents a genetically and clinically heterogeneous group of rare disorders characterized by progressive weakness and wasting of the muscles around the shoulders and hips—the "limb-girdle" areas.

What exactly is Limb-girdle muscular dystrophy?
Limb-girdle muscular dystrophy represents a genetically and clinically heterogeneous group of rare disorders characterized by progressive weakness and wasting of the muscles around the shoulders and hips—the "limb-girdle" areas. Because Limb-girdle muscular dystrophy is not a single disease but a spectrum of conditions, clinical presentation can vary significantly based on the specific genetic mutation involved. At DiseaseMaps.org, we have 51 community members living with Limb-girdle muscular dystrophy who share their unique journeys, reflecting the wide range of onset ages and progression rates found in this patient population.
How are the ICD-10 and ICD-9 codes used for Limb-girdle muscular dystrophy?
Medical coding, such as the ICD-10 code G71.02, is essential for documenting Limb-girdle muscular dystrophy within electronic health records, facilitating insurance billing, and tracking epidemiological data. While ICD-9 code 359.1 is now largely obsolete in clinical practice, it remains relevant when reviewing older medical records or historical research data. Precise coding is vital for patients, as it helps healthcare systems recognize the specific needs of those with Limb-girdle muscular dystrophy and ensures that diagnostic testing and therapeutic management are appropriately authorized.
What is the genetic basis of Limb-girdle muscular dystrophy?
Limb-girdle muscular dystrophy is caused by mutations in genes responsible for producing proteins essential for muscle cell integrity. Depending on the subtype, the condition can be inherited in different patterns:
- Autosomal Recessive (LGMD R): The most common form, where both parents carry a copy of the mutated gene.
- Autosomal Dominant (LGMD D): A rarer form where inheriting a single copy of the mutated gene from one parent is sufficient to cause the disease.
Because there are over 30 distinct subtypes identified to date, genetic counseling is a critical component of the care plan for anyone diagnosed with Limb-girdle muscular dystrophy. Identifying the specific genetic subtype is not only important for prognosis but also for determining eligibility for emerging gene-targeted clinical trials.
How do clinical experts diagnose Limb-girdle muscular dystrophy?
Diagnosis of Limb-girdle muscular dystrophy typically involves a multi-step clinical process. Because symptoms often overlap with other neuromuscular disorders, physicians utilize a combination of the following diagnostic tools:
- Serum Creatine Kinase (CK) levels: Often elevated in blood tests, indicating muscle damage.
- Electromyography (EMG): To assess the electrical activity of muscles and nerves.
- Muscle Biopsy: Used to examine protein expression patterns within muscle tissue.
- Genetic Testing: The gold standard for confirming the specific subtype of Limb-girdle muscular dystrophy by identifying the causative mutation.
Next steps
- Consult a neuromuscular specialist or a neurologist with expertise in rare muscular dystrophies.
- Request a referral to a certified genetic counselor to discuss family planning and inheritance patterns.
