S55.119 Laceration of radial artery at forearm level, unspecified arm

Name of the Condition

• Laceration of radial artery at forearm level, unspecified arm

Summary

A laceration of the radial artery at the forearm level, unspecified arm, involves a cut or tear in the radial artery within the forearm region of an unspecified arm. This injury may disrupt blood flow to the hand and fingers, depending on the severity of the arterial damage. The condition typically results from trauma and may be associated with other tissue injuries.

Causes

Direct trauma to the forearm, such as lacerations from sharp objects, blunt force injuries, or penetrating wounds. Fractures of the forearm bones (radius or ulna) may also damage the radial artery. Iatrogenic injuries during surgical procedures or medical interventions in the forearm area.

Risk Factors

• Participation in activities with a high risk of forearm trauma (e.g., contact sports, manual labor).
• Use of sharp tools or machinery without proper safety precautions.
• Preexisting vascular conditions that may weaken arterial walls.
• Proximity to the radial artery during surgical or interventional procedures.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the forearm.
• Weak or absent pulse in the wrist or hand (if arterial flow is compromised).
• Numbness, tingling, or coldness in the fingers (due to reduced blood flow).
• Pale or bluish discoloration of the hand or fingers.

Diagnosis

Physical examination to assess the injury site, pulse, and sensation. Imaging studies, such as ultrasound or angiography, may be used to evaluate arterial damage and blood flow. Assessment of associated injuries, such as fractures or nerve damage, may also be performed.

Treatment Options

• Direct pressure to control bleeding.
• Surgical repair or ligation of the radial artery, depending on the extent of damage.
• Revascularization procedures if blood flow is severely compromised.
• Pain management and wound care.
• Monitoring for complications, such as infection or ischemia.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and promptness of treatment. Most patients recover with appropriate care, but delayed treatment may lead to complications like tissue loss or functional impairment. Follow-up may include monitoring for signs of infection, assessing circulation, and rehabilitation if needed.

Complications

• Persistent bleeding or hematoma formation.
• Infection at the injury site.
• Ischemia or tissue damage due to reduced blood flow.
• Nerve injury or functional impairment.
• Long-term vascular complications, such as aneurysm or pseudoaneurysm.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Follow safety protocols when handling sharp tools or machinery.
• Seek prompt medical attention for forearm injuries to prevent complications.
• Maintain overall vascular health to reduce susceptibility to arterial damage.

When to Seek Professional Help

Seek immediate medical care if there is severe bleeding, loss of pulse in the wrist or hand, numbness, or discoloration of the fingers. Prompt evaluation is critical to prevent permanent damage.

Tips for Medical Coders

Document the specific arm (right/left) if known, as this may impact coding specificity. For unspecified arm, use S55.119. Ensure documentation supports the diagnosis, including details of the injury, assessment, and treatment. Verify that the code aligns with the clinical scenario and any associated injuries.
