S55.109D Unspecified injury of radial artery at forearm level, unspecified arm, subsequent encounter

Name of the Condition

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

Summary

An unspecified injury of the radial artery at the forearm level, unspecified arm, subsequent encounter, refers to a documented injury to the radial artery in the forearm region of an unspecified 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 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 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 radial 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).

Diagnosis

Physical examination to assess pulses, skin temperature, and sensory function. Doppler ultrasound or angiography to evaluate vascular integrity and blood flow. Review of medical history and imaging studies to confirm the injury and its location.

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. Anticoagulant therapy may be considered in specific cases to prevent thrombosis.

Prognosis and Follow-Up

Prognosis depends on the extent of arterial damage and timely intervention. Most minor injuries resolve with appropriate care, but severe cases may require long-term monitoring for functional impairment. Follow-up visits are essential to assess healing and detect complications.

Complications

Persistent bleeding or hematoma formation. Ischemia or tissue necrosis due to reduced blood flow. Infection at the injury site. Long-term vascular insufficiency or nerve damage.

Lifestyle & Prevention

Avoid high-risk activities without proper protection. Use safety equipment during manual labor or sports. Maintain awareness of anatomical variations that may increase injury risk. Follow post-procedure care instructions to minimize iatrogenic injuries.

When to Seek Professional Help

Seek immediate medical attention for severe bleeding, loss of pulse, or signs of ischemia (e.g., pale or blue discoloration of the hand). Contact a healthcare provider for persistent pain, swelling, or numbness that does not improve.

Tips for Medical Coders

Document the specific arm (if known) and encounter type (subsequent) to ensure accurate coding. Include details of the injury mechanism, diagnostic findings, and treatment provided. Verify that the code aligns with the clinical documentation and follow-up context.
