S85.311D Laceration of greater saphenous vein at lower leg level, right leg, subsequent encounter

Name of the Condition

• Laceration of greater saphenous vein at lower leg level, right leg, subsequent encounter

Summary

A laceration of the greater saphenous vein at the lower leg level, right leg, subsequent encounter, refers to a cut or tear to this superficial vein during a follow-up visit after an initial injury. This condition may disrupt venous drainage and require evaluation to assess healing, residual damage, or complications, such as persistent bleeding or thrombosis.

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) if fractures or internal injuries are suspected.

Treatment Options

• Wound care and compression to control bleeding and promote healing.
• Medications to manage pain or prevent infection.
• Surgical repair if the laceration is severe or causes significant venous obstruction.
• Monitoring for complications like thrombosis or infection.

Prognosis and Follow-Up

Prognosis depends on the extent of the injury and response to treatment. Follow-up care may involve repeated assessments to ensure proper healing and address any residual symptoms or complications. Most cases resolve with appropriate management, but severe injuries may require ongoing monitoring.

Complications

• Persistent bleeding or hematoma formation.
• Thrombosis (blood clot) in the affected vein.
• Infection at the injury site.
• Chronic venous insufficiency or swelling.

Lifestyle & Prevention

• Avoid activities that risk lower leg trauma until fully healed.
• Use protective gear during sports or high-risk activities.
• Maintain good leg circulation through regular movement and elevation when resting.
• Follow post-injury care instructions to reduce complication risk.

When to Seek Professional Help

Seek immediate care if bleeding is severe, uncontrolled, or accompanied by signs of shock (e.g., dizziness, rapid heartbeat). Contact a healthcare provider if pain, swelling, or discoloration worsens, or if new symptoms like numbness or coldness develop.

Tips for Medical Coders

Document the laterality (right leg) and encounter type (subsequent) clearly in the medical record. Ensure the laceration is confirmed and differentiated from other vein injuries. Code S85.311D is specific to a subsequent encounter; initial or acute encounters use different codes. Verify that the injury is localized to the lower leg level and involves the greater saphenous vein.
