M62.119 Other rupture of muscle (nontraumatic), unspecified shoulder

Name of the Condition

• Other rupture of muscle (nontraumatic), unspecified shoulder

Summary

Other rupture of muscle (nontraumatic), unspecified 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 activity modification to allow healing
• Pain management with medications or other therapies
• Physical therapy to restore strength and mobility
• Surgical intervention in severe or refractory cases

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 ensures proper healing and addresses any functional limitations.

Complications

• Chronic pain or weakness
• Reduced shoulder mobility
• Recurrent rupture
• Muscle atrophy or scarring

Lifestyle & Prevention

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

When to Seek Professional Help

Seek medical attention if you experience sudden or severe shoulder pain, visible muscle deformity, or difficulty moving the shoulder. Prompt evaluation is important to prevent complications and guide appropriate treatment.

Tips for Medical Coders

Document the shoulder involvement as unspecified when the exact side or specific muscle is not clearly identified. Ensure clinical documentation supports the nontraumatic nature of the rupture to justify the code assignment.
