S55.019D Laceration of ulnar artery at forearm level, unspecified arm, subsequent encounter

Name of the Condition

• Laceration of ulnar artery at forearm level, unspecified arm, subsequent encounter

Summary

A laceration of the ulnar artery at the forearm level, unspecified arm, subsequent encounter, refers to a cut or tear in the ulnar artery within the forearm region of an unspecified arm during a follow-up visit. This injury can disrupt blood flow to the hand and fingers, potentially leading to ischemia or other complications. The severity depends on the extent of arterial damage and associated tissue injury.

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

Diagnosis involves a physical examination to assess the injury site, check for pulses, and evaluate sensory or motor function. Imaging studies, such as Doppler ultrasound or angiography, may be used to confirm arterial damage and assess blood flow. Documentation of the injury mechanism and clinical findings is essential for accurate coding.

Treatment Options

Treatment may include wound care, pressure dressings, or surgical repair to restore arterial flow. Antibiotics or tetanus prophylaxis may be administered if indicated. Follow-up care focuses on monitoring for complications and ensuring proper healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timely intervention. Follow-up visits are necessary to assess healing, check for complications, and adjust treatment as needed. Long-term outcomes may include restored function or residual deficits based on the extent of damage.

Complications

Potential complications include persistent bleeding, infection, nerve damage, or chronic ischemia. Delayed treatment may increase the risk of tissue loss or functional impairment.

Lifestyle & Prevention

Avoid activities that increase the risk of forearm trauma. Use protective equipment during high-risk tasks. Maintain awareness of sharp objects and follow safety protocols to minimize injury risk.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, loss of pulse, or signs of ischemia (e.g., coldness, numbness). Follow up with a healthcare provider for persistent pain, swelling, or signs of infection.

Tips for Medical Coders

Code S55.019D is used for a subsequent encounter of a laceration of the ulnar artery at the forearm level, unspecified arm. Documentation must specify the encounter type (subsequent) and the anatomical location (unspecified arm). Ensure clinical notes support the diagnosis and encounter context for accurate coding.
