S85.159 Other specified injury of anterior tibial artery, unspecified leg

Name of the Condition

• Other specified injury of anterior tibial artery, unspecified leg

Summary

An injury to the anterior tibial artery, a major blood vessel in the lower leg, involves damage to this specific vessel. This condition may disrupt blood flow to the foot and lower leg, requiring prompt evaluation to assess vascular integrity and prevent complications such as ischemia or limb loss. The injury is classified as "other specified" to denote a type not covered by more specific codes, and the leg is unspecified in this code.

Causes

Direct trauma to the lower leg, such as from blunt force, penetrating injuries, or fractures. Surgical procedures or medical interventions in the lower leg area. Accidental or intentional injuries that disrupt vascular integrity.

Risk Factors

• Participation in high-impact activities or contact sports.
• History of lower leg fractures or vascular disease.
• Use of anticoagulant medications that increase bleeding risk.
• Advanced age or conditions affecting tissue integrity.

Symptoms

• Visible bleeding or hematoma at the injury site.
• Pain, swelling, or tenderness in the lower leg.
• Changes in skin color (e.g., pallor or cyanosis) due to reduced blood flow.
• Weak or absent pulses in the affected limb.
• Numbness, tingling, or coldness in the foot or toes.

Diagnosis

Physical examination to assess pulses, skin color, and signs of ischemia. Doppler ultrasound or angiography to evaluate blood flow and identify vascular damage. Imaging studies (e.g., CT angiography) may be used to confirm the extent of injury.

Treatment Options

• Immediate medical attention to restore blood flow, such as surgical repair or endovascular procedures.
• Medications to manage pain, swelling, or prevent clot formation.
• Monitoring for signs of complications, including ischemia or infection.
• Rehabilitation to restore function and mobility after treatment.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and timeliness of treatment. Early intervention improves outcomes, while delayed care may increase the risk of limb loss or chronic complications. Follow-up care includes monitoring for vascular function and addressing any residual symptoms.

Complications

• Ischemia or tissue damage due to reduced blood flow.
• Limb loss in severe or untreated cases.
• Infection at the injury site.
• Chronic pain or functional impairment.

Lifestyle & Prevention

• Use protective gear during high-risk activities to reduce trauma risk.
• Manage underlying conditions, such as diabetes or vascular disease, to support tissue health.
• Avoid unnecessary medical procedures that could disrupt vascular integrity without clear benefit.

When to Seek Professional Help

Seek immediate medical care if you experience sudden pain, swelling, or discoloration in the lower leg, especially after trauma. Prompt evaluation is critical to prevent permanent damage.

Tips for Medical Coders

Document the specific nature of the injury and whether the leg is specified (right, left, or bilateral) when available. Use this code for injuries not covered by more specific anterior tibial artery injury codes. Ensure clinical documentation supports the "other specified" classification and leg involvement.
