I80.243 Phlebitis and thrombophlebitis of peroneal vein, bilateral

Name of the Condition

• Phlebitis and Thrombophlebitis of Peroneal Vein, Bilateral

Summary

Phlebitis and thrombophlebitis of the peroneal vein, bilateral, involve inflammation and clot formation in both peroneal veins, which are deep veins in the lower legs. This condition can cause pain, swelling, and circulatory issues, and may lead to complications if not treated promptly.

Causes

The condition is typically caused by factors that disrupt normal blood flow or promote clotting, such as injury to the veins, prolonged immobility, infection, or underlying medical conditions that increase clotting risk. It may also occur due to catheter placement or other vascular interventions.

Risk Factors

• Advanced age
• Prolonged bed rest or inactivity
• Genetic clotting disorders
• Obesity
• Smoking
• Pregnancy or hormone-based medications
• Previous history of blood clots or varicose veins

Symptoms

• Pain or tenderness in both calves
• Swelling in both lower legs
• Warmth and redness over the affected veins
• Visible hardening or cord-like texture of the veins
• Low-grade fever (in some cases)

Diagnosis

Diagnosis may involve a physical examination, ultrasound imaging to detect clots, or blood tests such as D-dimer to assess clotting activity. Additional tests may be used to evaluate underlying causes or complications.

Treatment Options

Treatment may include anticoagulant medications to prevent clot growth, pain management, and measures to reduce swelling. In severe cases, thrombolytic therapy or surgical intervention may be considered.

Prognosis and Follow-Up

With prompt treatment, the prognosis is generally favorable, but complications such as deep vein thrombosis or pulmonary embolism can occur. Follow-up care often involves monitoring for recurrence and managing risk factors.

Complications

• Deep vein thrombosis (DVT)
• Pulmonary embolism
• Chronic venous insufficiency
• Post-thrombotic syndrome

Lifestyle & Prevention

• Maintain regular physical activity to promote circulation
• Avoid prolonged immobility, especially during travel or illness
• Stay hydrated and avoid smoking
• Wear compression stockings if recommended by a healthcare provider
• Manage underlying conditions that increase clotting risk

When to Seek Professional Help

Seek immediate medical attention if you experience sudden leg pain, swelling, warmth, or redness, or if you have difficulty breathing, as these may indicate a serious complication.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis is supported by clinical findings and imaging, if performed. The code I80.243 should be used when phlebitis and thrombophlebitis of the peroneal vein is present on both sides.
