S46.11 Strain of muscle, fascia and tendon of long head of biceps

Name of the Condition

• Strain of muscle, fascia and tendon of long head of biceps (ICD-10 Code: S46.11)

Summary

This condition involves a strain of the muscle, fascia, and tendon of the long head of the biceps, typically resulting from trauma or overuse. It can affect arm function and may require medical evaluation for proper management.

Causes

Causes include acute injuries such as falls, direct blows to the arm, or sudden forceful movements. Repetitive strain from activities like lifting or overhead work may also contribute to the injury.

Risk Factors

• Participation in contact sports, physically demanding occupations, poor muscle conditioning, and previous arm injuries increase susceptibility.

Symptoms

• Symptoms may include pain, swelling, bruising, weakness, limited range of motion, and a visible bulge in the upper arm (Popeye sign) in some cases.

Diagnosis

Diagnosis typically involves a physical examination to assess function and tenderness. Imaging tests like MRI or ultrasound may be used to evaluate the extent of muscle or tendon damage.

Treatment Options

• Treatment may include rest, ice, pain management, physical therapy to restore strength and mobility, and in severe cases, surgical repair of damaged structures.

Prognosis and Follow-Up

Recovery depends on the injury severity and treatment adherence. Most patients improve with conservative care, though follow-up may be needed to monitor healing and prevent recurrence.

Complications

• Potential complications include chronic pain, reduced strength, limited mobility, or re-injury if not properly managed.

Lifestyle & Prevention

• Avoiding overuse, maintaining proper form during physical activities, and strengthening the arm muscles can help reduce risk. Protective measures during sports or heavy lifting may also be beneficial.

When to Seek Professional Help

• Seek medical attention if pain is severe, mobility is significantly limited, or symptoms worsen despite rest. Immediate care is advised for suspected severe injuries or visible deformities.

Tips for Medical Coders

• Use S46.11 for a strain of the muscle, fascia, and tendon of the long head of the biceps. Ensure documentation supports the strain diagnosis and specifies the affected structure. Include details on injury mechanism and clinical findings to support accurate coding.
