ICD10 code of Nemaline Myopathy and ICD9 code

Nemaline Myopathy is primarily classified under the ICD-10 code G71.2 (congenital myopathies), while in the older ICD-9 system, it was categorized under 359.0 (congenital hereditary muscular dystrophy). These codes serve as the standard medical billing and reporting identifiers for Nemaline Myopathy in clinical and administrative settings worldwide.

What is the clinical classification of Nemaline Myopathy?

Nemaline Myopathy is a rare congenital neuromuscular disorder characterized by the presence of rod-shaped inclusions (nemaline bodies) in muscle fibers. Because the condition encompasses a broad spectrum of severity—ranging from severe neonatal forms to milder, adult-onset presentations—clinicians use these specific ICD codes to track the disease across global health systems. Understanding the diagnostic coding for Nemaline Myopathy is essential for accessing specialized care and insurance coverage for long-term management.

How is the diagnosis of Nemaline Myopathy confirmed?

Diagnosis typically involves a combination of clinical evaluation, genetic testing, and muscle biopsy. Because Nemaline Myopathy is genetically heterogeneous, clinicians look for mutations in genes such as NEB, ACTA1, and TPM3. Our 102 community members at DiseaseMaps.org emphasize that obtaining a precise genetic diagnosis is a vital step in navigating the complexities of this condition.

What are the common clinical features associated with the diagnosis?

Patients diagnosed with Nemaline Myopathy often present with a variety of symptoms that necessitate multidisciplinary care. Common clinical indicators include:

• Generalized muscle weakness, often affecting the proximal muscles (hips and shoulders).


• Hypotonia (low muscle tone), particularly in infants.


• Respiratory insufficiency due to diaphragm or intercostal muscle weakness.


• Bulbar dysfunction, which may impact speech and swallowing.


• Skeletal abnormalities, such as scoliosis or a high-arched palate.

Next steps

• Consult with a neuromuscular specialist or a pediatric neurologist to confirm your clinical coding and care plan.


• Connect with the 102 members of the Nemaline Myopathy community on DiseaseMaps.org to share experiences and coping strategies.


• Request a referral to a genetic counselor to discuss inheritance patterns and family testing options.
