S43.102D Unspecified dislocation of left acromioclavicular joint, subsequent encounter

Name of the Condition

• Unspecified Dislocation of Left Acromioclavicular Joint, Subsequent Encounter

Summary

An unspecified dislocation of the left acromioclavicular (AC) joint, subsequent encounter, refers to a follow-up visit for a previously diagnosed and treated dislocation of the clavicle from the acromion. This code is used when the patient is receiving active treatment or under active medical supervision for the condition during the healing phase.

Causes

The initial dislocation is typically caused by trauma, such as a direct blow to the shoulder or a fall onto an outstretched hand. The subsequent encounter code applies to ongoing care related to this injury, not the initial cause.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Previous shoulder injuries or dislocations.
• Age-related joint laxity or connective tissue disorders.

Symptoms

• Persistent pain and tenderness around the top of the shoulder.
• Visible deformity or swelling over the AC joint.
• Limited range of motion in the shoulder.
• Bruising or discoloration at the injury site.

Diagnosis

Diagnosis involves a physical examination to assess tenderness, deformity, and range of motion. Imaging tests like X-rays may be used to confirm healing or rule out complications. The subsequent encounter code is appropriate when the patient is under active treatment or follow-up for the dislocation.

Treatment Options

• Non-surgical treatments such as rest, ice, and physical therapy to restore movement and strength.
• Surgical options in severe cases to realign the joint and stabilize it using hardware or fixation devices.

Prognosis and Follow-Up

With appropriate treatment, many recover fully. Follow-up care may include physical therapy to restore strength and mobility, with regular monitoring to ensure proper healing and prevent recurrence.

Complications

• Chronic pain or instability of the AC joint.
• Nerve or blood vessel damage in severe cases.
• Limited shoulder function or arthritis over time.

Lifestyle & Prevention

• Avoid activities that risk shoulder injury until fully healed.
• Use protective gear during contact sports.
• Strengthen shoulder muscles through targeted exercises.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or movement becomes more limited. Immediate care is needed for signs of nerve or vascular compromise, such as numbness or discoloration.

Tips for Medical Coders

Use this code for a subsequent encounter for an unspecified dislocation of the left acromioclavicular joint. Ensure documentation supports active treatment or follow-up care. Do not use this code for the initial encounter or for a different joint side.
