S55.091 Other specified injury of ulnar artery at forearm level, right arm

Name of the Condition

• Other specified injury of ulnar artery at forearm level, right arm

Summary

An other specified injury of the ulnar artery at the forearm level, right arm, refers to damage to the ulnar artery in the forearm region of the right arm. This may result from trauma, such as lacerations, contusions, or penetrating injuries, and can affect blood flow to the hand and fingers. The severity of the injury depends on the extent of arterial damage and associated tissue involvement.

Causes

Direct trauma to the forearm, including lacerations from sharp objects, blunt force injuries, or penetrating wounds. Fractures of the forearm bones (radius or ulna) may also damage the ulnar 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 ulnar 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 pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate vascular integrity and blood flow. Imaging studies (e.g., X-rays) to identify associated fractures or soft tissue damage.

Treatment Options

• Direct pressure or tourniquet application to control bleeding.
• Surgical repair or revascularization of the ulnar artery.
• Anticoagulant or antiplatelet therapy to prevent clot formation.
• Pain management and wound care.
• Rehabilitation to restore function and prevent stiffness.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Early treatment improves outcomes, while delayed care may lead to complications like tissue ischemia or loss. Follow-up includes monitoring for signs of infection, assessing circulation, and evaluating functional recovery.

Complications

• Ischemia or tissue necrosis due to reduced blood flow.
• Infection at the injury site.
• Nerve damage affecting hand or finger sensation.
• Chronic pain or reduced mobility.
• Long-term vascular complications, such as aneurysm or stenosis.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, manual labor).
• Follow safety protocols when handling sharp tools or machinery.
• Maintain vascular health through regular exercise and a balanced diet.
• Avoid smoking, which can impair blood vessel healing.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, loss of pulse, or signs of ischemia (e.g., cold, pale, or numb fingers). Prompt evaluation is critical to prevent permanent tissue damage.

Tips for Medical Coders

Document the specific nature of the injury (e.g., laceration, contusion) and confirm the right-arm involvement. Ensure clinical details support the "other specified" designation, as this code is used when the injury type is documented but not covered by a more specific code. Include any associated injuries or procedures to provide complete context.
