M62.41 Contracture of muscle, shoulder

Name of the Condition

• Contracture of muscle, shoulder (ICD-10-CM: M62.41)

Summary

Contracture of muscle, shoulder refers to the abnormal shortening or tightening of muscle tissue in the shoulder region, which can restrict movement and cause stiffness. This condition may result from various underlying factors and can affect shoulder function and joint mobility.

Causes

Causes include prolonged immobilization, muscle injury, nerve damage, or underlying conditions that alter muscle fiber structure. In some cases, the exact cause remains unclear.

Risk Factors

• Prolonged bed rest or immobilization
• Neurological disorders affecting muscle control
• Previous muscle or joint injuries
• Chronic conditions like diabetes or arthritis
• Certain medications (e.g., corticosteroids)

Symptoms

• Stiffness or limited range of motion in the shoulder
• Pain or discomfort during movement
• Visible muscle tightness or deformity
• Difficulty performing daily activities

Diagnosis

Diagnosis typically involves a physical examination to assess muscle tone and joint mobility. Imaging (e.g., MRI) or electromyography (EMG) may be used to evaluate muscle structure and nerve function. Patient history and activity level are also considered.

Treatment Options

• Physical therapy to improve flexibility and strength
• Stretching or splinting to maintain joint mobility
• Pain management with medications (e.g., NSAIDs)
• Surgical intervention in severe cases

Prognosis and Follow-Up

Prognosis depends on the underlying cause and severity. Early intervention often improves outcomes. Follow-up may include regular physical therapy and monitoring for recurrence or complications.

Complications

• Chronic pain
• Permanent loss of range of motion
• Functional impairment
• Secondary joint issues

Lifestyle & Prevention

• Maintain regular shoulder exercises
• Avoid prolonged immobility
• Manage underlying conditions (e.g., diabetes)
• Use proper ergonomics during activities

When to Seek Professional Help

Seek care if shoulder stiffness or pain persists, worsens, or interferes with daily activities. Prompt evaluation is recommended for sudden onset or severe symptoms.

Tips for Medical Coders

Document the specific shoulder involvement and any contributing factors (e.g., trauma, immobility) to support code assignment. Ensure clinical correlation with the diagnosis.
