M62.412 Contracture of muscle, left shoulder

Name of the Condition

• Contracture of muscle, left shoulder (ICD-10-CM: M62.412)

Summary

Contracture of muscle, left shoulder refers to the abnormal shortening or tightening of muscle tissue in the left 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 left 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 affecting daily activities
• Secondary joint issues (e.g., arthritis)

Lifestyle & Prevention

• Maintain regular movement and exercise to prevent muscle stiffness
• Avoid prolonged immobilization of the shoulder
• Manage underlying conditions (e.g., diabetes) to reduce risk
• Use proper techniques during physical activities to avoid injury

When to Seek Professional Help

Seek medical attention if you experience persistent shoulder stiffness, pain, or difficulty moving the left shoulder, especially after injury or immobilization.

Tips for Medical Coders

Document the specific side (left shoulder) and any contributing factors (e.g., trauma, immobility) to support code assignment. Ensure clinical notes align with the diagnosis and specify the affected body part for accurate coding.
