S65.112D Laceration of radial artery at wrist and hand level of left arm, subsequent encounter

Name of the Condition

• Laceration of radial artery at wrist and hand level of left arm, subsequent encounter

Summary

A laceration of the radial artery at the wrist and hand level of the left arm involves a cut or tear in the radial artery in this anatomical region, typically resulting from trauma. This condition requires evaluation to assess vascular injury and determine appropriate management, as the radial artery is a critical blood vessel supplying the hand and fingers. The "subsequent encounter" designation indicates this is a follow-up episode of care for the injury.

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 radial nerve distribution (e.g., thumb, index finger).

Diagnosis

Diagnosis involves a thorough physical examination to assess the injury site, including evaluation of pulses, skin color, and sensation. Imaging studies such as Doppler ultrasound or angiography may be used to confirm vascular injury and assess blood flow. Clinical history of trauma or iatrogenic injury is also considered.

Treatment Options

Treatment may include wound closure, vascular repair, or ligation of the artery, depending on the severity of the injury. Hemostasis is achieved to control bleeding, and monitoring for complications like ischemia or infection is essential. Surgical intervention may be required for significant vessel damage.

Prognosis and Follow-Up

Prognosis depends on the extent of vascular injury and timely intervention. Follow-up care focuses on monitoring for complications, such as impaired circulation or nerve damage. Rehabilitation may be necessary to restore function, and ongoing evaluation ensures proper healing.

Complications

Potential complications include ischemia or tissue necrosis due to reduced blood flow, infection at the injury site, or nerve damage affecting sensation or movement. Chronic pain or vascular insufficiency may also occur if the injury is not adequately managed.

Lifestyle & Prevention

Preventive measures include using safety equipment during activities with hand/wrist trauma risks, avoiding unnecessary exposure to sharp objects, and adhering to proper techniques in manual labor or sports. Prompt medical attention for injuries can reduce complication risks.

When to Seek Professional Help

Seek immediate medical care for persistent bleeding, severe pain, or signs of impaired circulation (e.g., coolness, discoloration). Follow-up with a healthcare provider is necessary if symptoms worsen or new complications arise during recovery.

Tips for Medical Coders

Document the laterality (left arm) and encounter type (subsequent) clearly. Ensure clinical notes specify the anatomical level (wrist and hand) and confirm the radial artery as the affected vessel. Verify that the injury is a laceration and not another type of vascular injury to support accurate coding.
