M62.211 Nontraumatic ischemic infarction of muscle, right shoulder

Name of the Condition

• Nontraumatic Ischemic Infarction of Muscle, Right Shoulder (ICD-10-CM Code: M62.211)

Summary

Nontraumatic ischemic infarction of muscle is a condition where tissue death occurs in the muscle due to insufficient blood supply, not caused by trauma. In this case, the affected area is the right shoulder, which can lead to pain, functional impairment, and potential long-term damage to the shoulder muscles.

Causes

The condition arises from reduced blood flow to the muscle tissue of the right shoulder, often linked to vascular issues such as arterial obstruction, compression of blood vessels, or systemic diseases that impair circulation. Underlying causes may include atherosclerosis, thrombosis, or conditions like diabetes that affect vascular health.

Risk Factors

• Peripheral artery disease
• Diabetes mellitus
• Advanced age
• High cholesterol or hypertension
• Smoking
• Sedentary lifestyle
• Prior vascular conditions

Symptoms

• Sudden or gradual onset of muscle pain in the right shoulder
• Swelling or tenderness in the affected area
• Muscle weakness or reduced mobility of the shoulder
• Skin discoloration or temperature changes over the muscle
• Possible fever or systemic signs of inflammation

Diagnosis

Diagnosis involves a physical examination to assess muscle function and tenderness in the right shoulder, imaging tests (e.g., MRI, Doppler ultrasound) to evaluate blood flow, and blood tests to rule out infections or other underlying conditions. Clinical correlation with patient history is essential to confirm the diagnosis.

Treatment Options

• Medications to improve blood flow, such as anticoagulants or vasodilators
• Physical therapy to regain strength and function in the shoulder
• In severe cases, surgical intervention may be considered to restore blood supply

Prognosis and Follow-Up

Prognosis depends on the extent of muscle damage and timely treatment. Early intervention can improve outcomes, but severe cases may result in permanent muscle dysfunction. Follow-up care typically includes monitoring for recovery, rehabilitation, and management of underlying vascular conditions.

Complications

• Permanent muscle weakness or loss of function
• Chronic pain in the shoulder
• Skin ulcers or tissue necrosis if blood supply remains compromised
• Increased risk of infection in affected areas

Lifestyle & Prevention

• Maintain a healthy lifestyle with regular exercise to improve circulation
• Manage underlying conditions like diabetes or hypertension
• Avoid smoking and limit alcohol consumption
• Stay hydrated and maintain a balanced diet to support vascular health

When to Seek Professional Help

Seek medical attention if you experience sudden or worsening pain in the right shoulder, swelling, or signs of reduced blood flow (e.g., discoloration, coldness). Prompt evaluation is crucial to prevent permanent damage.

Tips for Medical Coders

When coding M62.211, ensure documentation specifies the nontraumatic nature of the ischemic infarction and the right shoulder as the affected site. Clinical notes should support the diagnosis, including details of symptoms, diagnostic tests, and any underlying vascular conditions. Accurate coding requires clear differentiation from traumatic injuries or other muscle disorders.
