S46.122 Laceration of muscle, fascia and tendon of long head of biceps, left arm

Name of the Condition

• Laceration of Muscle, Fascia, and Tendon of Long Head of Biceps, Left Arm (ICD-10 Code: S46.122)

Summary

A laceration of the long head of the biceps is a traumatic tear or cut affecting the muscle, fascia, and tendon in the upper arm. This injury disrupts arm function and requires medical evaluation for appropriate management.

Causes

This type of laceration typically results from acute trauma, such as sharp object injuries, accidents, sports-related incidents, or falls that apply significant force to the arm.

Risk Factors

• Engaging in high-impact sports or activities with a risk of arm injury.
• Occupations involving physical labor or repetitive arm movements.
• Previous arm injuries that may weaken the tissue.

Symptoms

• Pain, swelling, and bruising in the upper arm.
• Tenderness at the site of injury.
• Limited range of motion in the arm or shoulder.
• Visible cuts or tears on the skin.

Diagnosis

Diagnosis is made through a physical examination to assess tenderness, function, and visible damage. Imaging tests like MRI or ultrasound may be used to evaluate the extent of the laceration and involvement of the tendon or muscle tissue.

Treatment Options

• Wound cleaning and closure to prevent infection.
• Immobilization using splints or slings to support healing.
• Surgical repair for severe cases to restore muscle and tendon integrity.
• Physical therapy to regain strength and mobility.

Prognosis and Follow-Up

Recovery depends on the severity of the injury and adherence to treatment. Most patients regain function with proper care, but follow-up appointments may be needed to monitor healing and adjust therapy.

Complications

• Infection at the injury site.
• Persistent pain or weakness.
• Limited range of motion.
• Nerve or vascular damage in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Avoid repetitive strain on the arm.
• Maintain strength and flexibility through regular exercise.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible tissue damage, or inability to move the arm.

Tips for Medical Coders

Document the location (left arm) and confirm the involvement of muscle, fascia, and tendon. Ensure the injury is clearly described as a laceration to support accurate coding.
