S43.412S Sprain of left coracohumeral (ligament), sequela

Name of the Condition

• Sprain of left coracohumeral (ligament), sequela

Summary

A sprain of the left coracohumeral ligament, sequela, refers to the residual effects of a previous injury to the ligament connecting the coracoid process to the humerus in the left shoulder. This condition results from prior overstretching or tearing of the ligament, leading to ongoing functional or structural changes. Sequela may involve persistent instability, limited range of motion, or chronic pain, depending on the severity of the initial injury and healing process.

Causes

The sequela arises from a previous sprain of the left coracohumeral ligament, typically caused by trauma, overuse, or sudden force applied to the shoulder. The residual effects develop as a consequence of incomplete healing, scar tissue formation, or structural damage from the initial injury.

Risk Factors

• History of shoulder trauma or injury
• Previous sprains or ligament damage
• Inadequate rehabilitation after initial injury
• Activities requiring repetitive shoulder motion

Symptoms

• Persistent pain or discomfort in the left shoulder
• Reduced range of motion or stiffness
• Feeling of shoulder instability
• Possible swelling or tenderness in the affected area

Diagnosis

Diagnosis involves a physical examination to assess shoulder stability, range of motion, and tenderness. Patient history is reviewed to confirm a prior injury to the left coracohumeral ligament. Imaging, such as X-rays or MRI, may be used to evaluate residual ligament damage or structural changes.

Treatment Options

• Physical therapy to improve strength and mobility
• Pain management with medications or injections
• Activity modification to avoid aggravating movements
• In some cases, surgical intervention for severe instability

Prognosis and Follow-Up

Prognosis depends on the extent of residual damage and adherence to treatment. Most patients experience improved function with rehabilitation, though some may have persistent limitations. Follow-up care focuses on monitoring progress and adjusting treatment as needed.

Complications

• Chronic shoulder instability
• Persistent pain or stiffness
• Increased risk of re-injury
• Long-term functional impairment

Lifestyle & Prevention

• Engage in regular shoulder-strengthening exercises
• Avoid repetitive overhead motions or heavy lifting
• Use proper form during physical activities
• Seek prompt treatment for shoulder injuries to prevent sequela

When to Seek Professional Help

Consult a healthcare provider if you experience worsening pain, significant loss of motion, or new instability in the left shoulder. Early evaluation can help prevent further complications.

Tips for Medical Coders

Document the sequela status and specify the left coracohumeral ligament involvement. Ensure the code S43.412S is used only when the condition represents a residual effect of a prior sprain, with clear clinical correlation to the initial injury.
