S43.111S Subluxation of right acromioclavicular joint, sequela

Name of the Condition

• Subluxation of Right Acromioclavicular Joint, Sequela

Summary

This condition represents the residual effects of a prior partial displacement of the right acromioclavicular (AC) joint, where the clavicle meets the acromion of the scapula. It may result in persistent pain, instability, or restricted shoulder movement following the initial injury.

Causes

Subluxation of the right AC joint typically stems from traumatic events like falls, direct shoulder blows, or forceful movements. The sequela arises as a complication of the original injury, reflecting incomplete healing or chronic instability.

Risk Factors

• Participation in contact sports or activities with high fall risk.
• Previous shoulder injuries or ligamentous instability.
• Age-related degeneration or connective tissue disorders.
• Occupations requiring repetitive arm or shoulder movements.

Symptoms

• Chronic pain and tenderness around the top of the right shoulder.
• Visible deformity or swelling over the acromioclavicular joint.
• Limited range of motion in the shoulder.
• Sensation of the joint feeling unstable or "popping out."

Diagnosis

Diagnosis involves a physical examination to assess tenderness, deformity, and range of motion. Imaging tests like X-rays may be used to confirm residual displacement and rule out fractures. Documentation should link the sequela to the original injury.

Treatment Options

• Non-surgical treatments such as rest, ice, and physical therapy to restore movement and strength.
• Surgical options in severe cases to stabilize the joint.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and adherence to treatment. Regular follow-up may be needed to monitor for complications or recurrence. Physical therapy often improves outcomes, but some residual symptoms may persist.

Complications

• Chronic pain or instability.
• Progressive joint degeneration.
• Reduced shoulder function.

Lifestyle & Prevention

• Avoid activities that stress the shoulder.
• Use protective gear during sports.
• Strengthen shoulder muscles through exercise.
• Maintain a healthy weight to reduce joint strain.

When to Seek Professional Help

Seek care if pain worsens, movement is severely restricted, or deformity is noticeable. Prompt evaluation is important if symptoms interfere with daily activities.

Tips for Medical Coders

Document the sequela clearly, linking it to the original injury. Ensure the code S43.111S is used only when the condition is a direct result of a prior subluxation of the right AC joint. Include details on chronicity and residual effects in clinical notes.
