S55.002D Unspecified injury of ulnar artery at forearm level, left arm, subsequent encounter

Name of the Condition

• Unspecified injury of ulnar artery at forearm level, left arm, subsequent encounter

Summary

An unspecified injury of the ulnar artery at the forearm level, left arm, subsequent encounter refers to damage to the ulnar artery in the forearm region of the left arm during a follow-up visit. 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 left forearm, including lacerations from sharp objects, blunt force injuries, or penetrating wounds. Fractures of the left forearm bones (radius or ulna) may also damage the ulnar artery. Iatrogenic injuries during surgical procedures or medical interventions in the left forearm area.

Risk Factors

• Participation in activities with a high risk of left 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 on the left arm.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the left forearm.
• Weak or absent pulse in the left wrist or hand (if arterial flow is compromised).
• Numbness, tingling, or coldness in the fingers (due to reduced blood flow).

Diagnosis

Physical examination to assess pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate vascular integrity and blood flow. Review of prior imaging or procedural notes to confirm the nature of the injury.

Treatment Options

Conservative management with observation and monitoring for complications. Surgical repair or revascularization if significant arterial damage is present. Pain management and wound care as needed. Physical therapy to restore function and prevent stiffness.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Most patients recover with appropriate treatment, but residual deficits may occur. Follow-up visits to monitor healing, assess circulation, and address any ongoing symptoms.

Complications

Persistent ischemia or tissue damage due to inadequate blood flow. Infection at the injury site. Nerve injury leading to sensory or motor deficits. Long-term vascular complications, such as aneurysm or stenosis.

Lifestyle & Prevention

Avoid activities that increase risk of forearm trauma. Use protective equipment during high-risk tasks. Maintain awareness of vascular health and report symptoms promptly. Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate care for severe bleeding, worsening pain, or signs of ischemia (e.g., pale or blue discoloration of the hand). Contact a healthcare provider for persistent symptoms or concerns during recovery.

Tips for Medical Coders

Document the laterality (left arm) and encounter type (subsequent) clearly. Include details about the injury mechanism, treatment provided, and any complications to support code assignment. Ensure documentation aligns with the specificity of the code for accurate reporting.
