S25.111S Minor laceration of right innominate or subclavian artery, sequela

Name of the Condition

• Minor laceration of right innominate or subclavian artery, sequela

Summary

This condition represents a minor laceration of the right innominate or subclavian artery that persists as a sequela (long-term effect) of a prior injury. The innominate and subclavian arteries are major vessels supplying blood to the upper body and arm. Sequelae may include residual vascular changes, scarring, or functional impairment resulting from the initial trauma.

Causes

Sequelae of a minor laceration to the right innominate or subclavian artery arise from a prior traumatic event, such as motor vehicle accidents, penetrating wounds, or blunt force trauma to the chest or neck. Medical procedures involving these areas may also lead to vascular injury, with lasting effects manifesting as sequelae.

Risk Factors

• History of trauma or injury to the chest, neck, or shoulder.
• Prior surgical interventions in the thoracic or cervical region.
• Occupational or recreational activities with high trauma risk (e.g., contact sports, construction).
• Age-related factors, such as increased susceptibility to falls or accidents in older adults.

Symptoms

• Persistent mild pain or discomfort in the neck, chest, or shoulder.
• Mild swelling or bruising in the affected area.
• Possible reduced pulse or blood flow in the right arm.
• Occasional dizziness or lightheadedness (if vascular compromise persists).
• Scarring or tissue changes at the site of the original injury.

Diagnosis

Diagnosis involves a physical examination to assess for residual signs of vascular compromise or tissue damage. Imaging studies, such as CT angiography or ultrasound, may be used to evaluate the artery’s structure and function. Clinical history of the prior injury is critical to confirm the sequela.

Treatment Options

Management focuses on monitoring and addressing residual symptoms. Conservative measures, such as pain management or physical therapy, may be recommended. In cases of persistent vascular issues, further evaluation by a vascular specialist may be necessary to determine if intervention is required.

Prognosis and Follow-Up

Prognosis depends on the extent of the original injury and any residual vascular or tissue damage. Most patients recover with minimal long-term effects, but follow-up care is important to monitor for complications. Regular check-ups may be advised to assess vascular function and overall recovery.

Complications

• Chronic pain or discomfort at the injury site.
• Reduced blood flow to the right arm (ischemia).
• Formation of scar tissue affecting mobility.
• Rarely, aneurysm or pseudoaneurysm development at the site of the prior laceration.

Lifestyle & Prevention

• Avoid activities that may strain the neck or shoulder (e.g., heavy lifting) until cleared by a healthcare provider.
• Use protective gear during high-risk activities to prevent trauma.
• Maintain regular follow-up appointments to monitor vascular health.
• Report any new or worsening symptoms (e.g., increased pain, swelling) promptly.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, sudden swelling, or signs of reduced blood flow (e.g., coldness, numbness) in the right arm. Contact your healthcare provider for persistent symptoms or concerns about your recovery.

Tips for Medical Coders

This code (S25.111S) is used for a sequela of a minor laceration of the right innominate or subclavian artery. Document the prior injury and its lasting effects clearly, including clinical evidence of residual symptoms or vascular changes. Ensure the sequela is directly linked to the original trauma to support accurate coding.
