S55.011D Laceration of ulnar artery at forearm level, right arm, subsequent encounter

Name of the Condition

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

Summary

A laceration of the ulnar artery at the forearm level, right arm, subsequent encounter, refers to a cut or tear in the ulnar artery within the forearm region of the right arm during a follow-up visit. This type of injury can disrupt blood flow to the hand and fingers, depending on the severity of the arterial damage. The condition may result from trauma and can involve associated tissue injury, such as damage to surrounding nerves or muscles.

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 may be used to identify associated fractures or soft tissue damage.

Treatment Options

• Direct pressure to control bleeding.
• Surgical repair or revascularization of the artery.
• Wound closure and debridement if necessary.
• Antibiotics to prevent infection.
• Pain management and monitoring of circulation.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Follow-up care may include monitoring for complications, such as infection or impaired circulation. Rehabilitation may be needed to restore function.

Complications

• Persistent bleeding or hematoma.
• Infection at the injury site.
• Nerve damage leading to numbness or weakness.
• Ischemia or tissue loss due to reduced blood flow.
• Scarring or functional impairment.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Follow safety protocols when handling sharp objects or machinery.
• Maintain awareness of forearm anatomy during medical procedures.
• Seek prompt treatment for minor injuries to prevent progression.

When to Seek Professional Help

• Uncontrolled bleeding or worsening pain.
• Changes in skin color, temperature, or sensation in the hand or fingers.
• Signs of infection, such as redness, swelling, or pus.
• Persistent numbness or weakness after injury.

Tips for Medical Coders

Document the laterality (right arm) and encounter type (subsequent) to ensure accurate coding. Include details of the injury mechanism, associated complications, and treatment provided. Verify that the code aligns with the clinical documentation and follow-up context.
