M62.11 Other rupture of muscle (nontraumatic), shoulder

Name of the Condition

• Other rupture of muscle (nontraumatic), shoulder

Summary

Other rupture of muscle (nontraumatic), shoulder refers to the tearing or splitting of muscle fibers in the shoulder region without associated trauma. This condition can disrupt muscle structure and function, potentially leading to pain, weakness, or impaired shoulder movement.

Causes

The exact cause of nontraumatic muscle rupture in the shoulder is not fully understood. It may involve degenerative changes within the muscle, overuse, underlying systemic conditions, or factors that weaken muscle integrity, such as certain metabolic or connective tissue disorders.

Risk Factors

• Increasing age
• Repetitive or improper shoulder muscle use
• Pre-existing muscle or connective tissue disorders
• Certain systemic diseases affecting muscle health
• Use of medications that weaken muscle (e.g., corticosteroids)

Symptoms

• Sudden or gradual onset of pain in the shoulder muscle
• Weakness or reduced shoulder muscle strength
• Visible bulging or deformity in the shoulder muscle
• Difficulty with shoulder movement or performing tasks
• Possible bruising or swelling in the shoulder area

Diagnosis

Diagnosis typically involves a physical examination to assess shoulder muscle integrity and function. Imaging tests such as MRI or ultrasound may be used to visualize muscle structure and confirm rupture. Patient history and activity level are also evaluated to rule out traumatic causes.

Treatment Options

• Rest and avoidance of activities that strain the affected shoulder muscle
• Physical therapy to strengthen surrounding muscles and improve function
• Pain management using NSAIDs or other appropriate medications
• In severe cases, surgical intervention may be considered

Prognosis and Follow-Up

Prognosis depends on the severity of the rupture and adherence to treatment. Most cases improve with conservative management, but recovery may take weeks to months. Follow-up care may include regular physical therapy and monitoring for complications.

Complications

• Chronic pain or weakness in the shoulder
• Limited range of motion
• Re-rupture of the muscle
• Nerve damage in severe cases

Lifestyle & Prevention

• Avoid overuse or improper shoulder movements
• Maintain muscle strength and flexibility through regular exercise
• Use proper form during physical activities
• Address underlying health conditions that may weaken muscles

When to Seek Professional Help

Seek medical attention if you experience sudden, severe shoulder pain, visible muscle deformity, or significant weakness that impairs movement. Prompt evaluation is important to rule out other conditions and initiate appropriate treatment.

Tips for Medical Coders

When coding for M62.11, ensure documentation specifies the shoulder as the site of the nontraumatic muscle rupture. Verify that the condition is not trauma-related, as this code excludes traumatic ruptures. Accurate clinical details, such as onset, symptoms, and diagnostic findings, support proper code assignment.
