S65.011D Laceration of ulnar artery at wrist and hand level of right arm, subsequent encounter

Name of the Condition

• Laceration of ulnar artery at wrist and hand level of right arm, subsequent encounter

Summary

A laceration of the ulnar artery at the wrist and hand level of the right arm, subsequent encounter, refers to a documented cut or tear in the ulnar artery in this anatomical region during a follow-up visit. This condition requires evaluation to assess healing, vascular status, and any ongoing complications, as the ulnar artery is critical for perfusion of the distal upper extremity.

Causes

Direct trauma to the wrist or hand, such as lacerations, puncture wounds, or crush injuries. Penetrating injuries from sharp objects like glass, knives, or tools. Blunt force trauma causing vessel compression or disruption. Iatrogenic injury during surgical procedures involving the wrist or hand.

Risk Factors

• Participation in activities with a risk of hand or wrist trauma (e.g., sports, manual labor).
• Use of sharp objects or tools without proper safety precautions.
• Preexisting vascular conditions that may weaken vessel integrity.
• Advanced age, which may be associated with reduced tissue resilience.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the wrist or hand.
• Weak or absent pulses in the affected digits.
• Coolness, pallor, or discoloration of the hand or fingers.
• Numbness or tingling in the ulnar nerve distribution (e.g., little finger, ring finger).

Diagnosis

Physical examination to assess for vascular compromise, including pulse palpation and capillary refill. Doppler ultrasound or angiography to evaluate arterial flow and detect occlusion or pseudoaneurysm. Review of prior imaging or surgical reports to confirm the initial injury and treatment. Assessment of functional status and any residual symptoms.

Treatment Options

Wound care and monitoring for infection or healing complications. Vascular imaging to reassess arterial patency if symptoms persist. Referral to a vascular specialist for further intervention if ischemia or other complications are identified. Pain management and activity modification as needed.

Prognosis and Follow-Up

Prognosis depends on the extent of the initial injury, timely treatment, and absence of complications. Follow-up visits are essential to monitor healing, vascular status, and functional recovery. Long-term outcomes may include restored perfusion, residual deficits, or the need for additional procedures.

Complications

Persistent ischemia or tissue necrosis due to inadequate blood flow. Infection at the injury site. Pseudoaneurysm or arteriovenous fistula formation. Chronic pain or nerve dysfunction. Reduced range of motion or functional impairment in the hand or wrist.

Lifestyle & Prevention

Use protective gear during high-risk activities (e.g., sports, manual labor). Handle sharp objects with care and follow safety protocols. Maintain awareness of hand and wrist positioning to avoid trauma. Seek prompt medical attention for injuries to minimize complications.

When to Seek Professional Help

Worsening pain, swelling, or discoloration of the hand or fingers. Persistent numbness, tingling, or weakness. Signs of infection, such as redness, warmth, or pus. Reduced or absent pulses in the affected digits. Any concerns about healing or functional status.

Tips for Medical Coders

Document the laterality (right arm) and encounter type (subsequent) to ensure accurate coding. Include details about the injury mechanism, treatment provided, and any complications to support code assignment. Verify that the diagnosis aligns with the anatomical location and clinical findings.
