S43.432 Superior glenoid labrum lesion of left shoulder

Name of the Condition

• Superior Glenoid Labrum Lesion of Left Shoulder (Superior Labrum Anterior to Posterior Tear, SLAP Lesion)

Summary

A superior glenoid labrum lesion, known as a SLAP tear, is an injury to the labrum, a ring of cartilage surrounding the shoulder socket. This condition specifically affects the left shoulder and can result from trauma or repetitive shoulder use, impacting shoulder stability and function.

Causes

Common causes include acute trauma, such as a fall on an outstretched arm, forceful lifting, or repetitive overhead activities common in sports like baseball or swimming.

Risk Factors

• Participation in overhead sports, previous shoulder injuries, and occupations requiring repetitive shoulder movement can increase the risk. Aging can also weaken shoulder structures, making injuries more likely.

Symptoms

• Symptoms typically include shoulder pain, particularly with lifting or throwing, a sensation of locking or catching in the shoulder, decreased range of motion, and sometimes a popping or clicking sound.

Diagnosis

Diagnosis is typically made through a combination of physical examination tests and imaging studies such as MRI (Magnetic Resonance Imaging) to visualize the labrum and assess any tears.

Treatment Options

• Initial treatment may involve rest, physical therapy, and anti-inflammatory medications to reduce pain and inflammation. Severe cases may require surgical intervention, such as arthroscopic repair, to restore shoulder stability.

Prognosis and Follow-Up

Prognosis depends on the severity of the lesion and the chosen treatment. Most patients experience improved function with appropriate care, but recovery may take several months. Follow-up appointments are important to monitor healing and adjust rehabilitation plans as needed.

Complications

Potential complications include chronic shoulder instability, persistent pain, or re-injury if the labrum does not heal properly. In some cases, surgery may lead to stiffness or infection, though these are rare.

Lifestyle & Prevention

• Avoid repetitive overhead motions or heavy lifting to reduce strain on the shoulder. Strengthening shoulder muscles through targeted exercises can improve stability. Using proper form during sports or work activities may also lower risk.

When to Seek Professional Help

Seek medical attention if shoulder pain is severe, worsens over time, or interferes with daily activities. Prompt evaluation is recommended if symptoms like locking, catching, or significant loss of motion occur, as these may indicate a more serious injury.

Tips for Medical Coders

This code (S43.432) specifies a superior glenoid labrum lesion of the left shoulder. Documentation should clearly indicate the location (left shoulder) and the nature of the lesion (superior glenoid labrum) to support accurate coding. Ensure clinical notes align with the specific anatomical site and laterality for proper assignment.
