S46.112 Strain of muscle, fascia and tendon of long head of biceps, left arm

Name of the Condition

• Strain of muscle, fascia and tendon of long head of biceps, left arm (ICD-10 Code: S46.112)

Summary

This condition involves a strain of the muscle, fascia, and tendon of the long head of the biceps in the left arm. It typically results from trauma or overuse and may affect arm function, requiring 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, but severe strains may require extended rehabilitation or surgery. Follow-up ensures proper healing and functional recovery.

Complications

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

Lifestyle & Prevention

• Strengthening exercises, proper lifting techniques, and avoiding overuse can help prevent strains. Warming up before physical activity and using protective gear during sports may also reduce risk.

When to Seek Professional Help

• Seek care if pain is severe, mobility is significantly limited, or symptoms worsen. Prompt evaluation is important for proper diagnosis and treatment.

Tips for Medical Coders

• Use S46.112 for a strain of the long head of the biceps in the left arm. Ensure documentation specifies the affected side and confirms the strain involves muscle, fascia, and tendon. Verify no other injuries or conditions are present that would require additional coding.
