ICD10 code of Becker muscular dystrophy and ICD9 code

The ICD-10-CM code for Becker muscular dystrophy is G71.01, while the ICD-9-CM code historically used to classify this condition is 359.1. These codes are essential for medical billing, insurance authorization, and clinical documentation within healthcare systems globally.

What is Becker muscular dystrophy?

Becker muscular dystrophy (BMD) is an X-linked recessive, progressive neuromuscular disorder characterized by the weakness and wasting of skeletal muscles, specifically the pelvic and shoulder girdles. Unlike the more severe Duchenne muscular dystrophy, Becker muscular dystrophy is caused by a mutation in the DMD gene that results in the production of a truncated, partially functional form of the protein dystrophin. Because the protein is present but dysfunctional, the clinical progression of Becker muscular dystrophy is generally slower and more variable than other forms of dystrophinopathy.

How is Becker muscular dystrophy classified in medical coding?

Accurate coding is vital for patients seeking specialized care and insurance coverage. The ICD-10-CM code G71.01 specifically designates Becker muscular dystrophy, allowing clinicians to distinguish it from limb-girdle muscular dystrophies or Duchenne muscular dystrophy. In older medical records or legacy systems, the ICD-9-CM code 359.1 (Hereditary progressive muscular dystrophy) was the standard classification used for Becker muscular dystrophy. Utilizing these precise codes ensures that health records accurately reflect the specific nature of the condition, which is critical for accessing disease-specific treatments and multidisciplinary care protocols.

What are the clinical characteristics of Becker muscular dystrophy?

The onset of symptoms for Becker muscular dystrophy typically occurs in late childhood or adolescence, though it can manifest as late as the mid-20s. Patients often experience a progressive decline in muscle strength, which can be managed through proactive intervention. Common features often reported by the 93 members of the DiseaseMaps community include:

• Progressive weakness in the proximal muscles (hips, thighs, and shoulders).


• Calf muscle hypertrophy (enlargement due to pseudohypertrophy).


• Difficulty climbing stairs, running, or rising from a sitting position.


• Cardiac involvement, such as dilated cardiomyopathy, which may occur even in patients with mild skeletal muscle symptoms.


• Muscle cramps and exercise-induced myoglobinuria.

Is Becker muscular dystrophy hereditary?

Yes, Becker muscular dystrophy is an X-linked recessive condition, meaning the mutation is located on the X chromosome. Because of this inheritance pattern, it primarily affects males, who have only one X chromosome. Females, who have two X chromosomes, are typically carriers and usually do not exhibit symptoms, though some may experience mild muscle weakness or cardiac issues. Genetic counseling is strongly recommended for families affected by Becker muscular dystrophy to understand the risk of recurrence and to discuss family planning options, such as prenatal or preimplantation genetic testing.

Next steps

• Consult a neuromuscular specialist or a neurologist familiar with dystrophinopathies to confirm your diagnosis and coordinate care.


• Schedule a baseline cardiac evaluation, including an echocardiogram and EKG, as heart health is a priority in Becker muscular dystrophy management.


• Connect with the 93 members of the DiseaseMaps community to share experiences and receive peer support.


• Work with a physical therapist to develop a maintenance exercise program that avoids overexertion while promoting muscle health.
