S55.102D Unspecified injury of radial artery at forearm level, left arm, subsequent encounter

Name of the Condition

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

Summary

An unspecified injury of the radial artery at the forearm level, left arm, subsequent encounter, involves damage to the radial artery in the forearm region of the left arm during a follow-up care phase. This may result from trauma, such as lacerations, contusions, or penetrating injuries, and can affect blood flow to the hand and fingers. The severity 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 forearm bones (radius or ulna) may also damage the radial 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 radial 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 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 and subsequent care context.

Treatment Options

Conservative management with observation and monitoring for complications. Vascular repair or reconstruction if blood flow is compromised. Pain management and wound care as needed. Follow-up imaging to assess healing and arterial patency.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Regular follow-up to monitor for complications, such as thrombosis or ischemia. Long-term assessment of functional recovery and vascular status.

Complications

Thrombosis or occlusion of the radial artery. Ischemia or tissue necrosis of the hand or fingers. Infection at the injury site. Chronic pain or vascular insufficiency.

Lifestyle & Prevention

Avoid activities that increase risk of forearm trauma. Use protective equipment during high-risk tasks. Manage underlying vascular conditions. Follow post-injury care instructions to promote healing.

When to Seek Professional Help

Persistent pain, swelling, or discoloration of the left hand or fingers. Weak or absent pulse in the wrist. Numbness, tingling, or coldness that does not improve. Signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Use this code for a subsequent encounter for an unspecified injury of the radial artery at the forearm level, left arm. Document the laterality (left arm) and encounter type (subsequent) clearly. Ensure the injury is not specified as initial or acute, and no additional details about the injury mechanism are included unless supported by clinical documentation.
