G71.01
Duchenne or Becker muscular dystrophy
Clinical Classification Guidelines
Inclusion Terms
- Autosomal recessive, childhood type, muscular dystrophy resembling Duchenne or Becker muscular dystrophy
- Benign [Becker] muscular dystrophy
- Severe [Duchenne] muscular dystrophy
Medical Intelligence & Overview
Duchenne and Becker muscular dystrophies are inherited genetic disorders characterized by progressive muscle weakness and degeneration. These conditions primarily affect boys during childhood, leading to varying degrees of disability over time. They are caused by mutations in a gene responsible for producing dystrophin, a protein vital for muscle health. While Duchenne muscular dystrophy is more severe and progresses rapidly, Becker muscular dystrophy tends to be milder and progresses more slowly. Both are classified under the ICD-10 code G71.01 and are inherited in an autosomal recessive pattern.
Causes & Symptoms
Clinical Causes: Mutations in the dystrophin gene on the X chromosome Inheritance pattern: autosomal recessive transmission, meaning two copies of the mutated gene must be inherited for the disorder to be expressed Genetic variations leading to abnormal or deficient dystrophin protein production Family history of muscular dystrophy
Key Symptoms: Muscle weakness that begins in the pelvic and thigh muscles Delayed motor milestones such as sitting, walking, or running Difficulty rising from a seated or lying position (Gowers' sign) Frequent falls and muscle fatigue Calf muscle enlargement (pseudohypertrophy) Problems with coordination and gait Progressive muscle wasting leading to mobility challenges In some cases, cardiomyopathy or weakness in the heart muscle
Diagnostic & Treatment
Diagnosis Path: Blood tests for elevated levels of creatine kinase (CK), an enzyme released when muscle fibers are damaged Genetic testing to identify mutations in the dystrophin gene Muscle biopsy to examine dystrophin protein presence and muscle tissue characteristics Electromyography (EMG) to assess electrical activity of muscle tissues Cardiac assessments to evaluate any heart involvement
Treatment Protocols: Physical therapy to maintain muscle strength and flexibility Occupational therapy to support daily activities and adaptations Medications such as corticosteroids to reduce inflammation and slow muscle deterioration Cardiac therapies to address heart-related complications Assistive devices like wheelchairs and braces to promote mobility Surgical interventions when necessary for scoliosis or other deformities Emerging gene therapies and experimental treatments under clinical trials
Clinical Advice & FAQs
Billing Guidance
Is G71.01 a billable ICD-10 code?
Yes, G71.01 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report G71.01?
Clinical documentation must specify the nature of Duchenne or Becker muscular dystrophy and any associated comorbidities for accurate reporting.
