I80.213 Phlebitis and thrombophlebitis of iliac vein, bilateral

Name of the Condition

• Phlebitis and Thrombophlebitis of Iliac Vein, Bilateral

Summary

Phlebitis and thrombophlebitis of the iliac vein, bilateral, involve inflammation and clot formation in both iliac veins, which are large deep veins in the pelvis. 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 vein, 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 the lower abdomen or groin (bilateral)
• Swelling in both 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 necessary.

Prognosis and Follow-Up

With prompt treatment, the prognosis is generally favorable, but complications such as pulmonary embolism or post-thrombotic syndrome can occur. Follow-up care typically involves monitoring for recurrence and managing risk factors.

Complications

• Pulmonary embolism
• Post-thrombotic syndrome (chronic pain, swelling, or skin changes)
• Infection of the affected vein
• Chronic venous insufficiency

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Quit smoking
• Stay hydrated
• Follow prescribed treatments for underlying conditions (e.g., clotting disorders)

When to Seek Professional Help

Seek immediate medical attention if you experience sudden chest pain, shortness of breath, severe leg swelling, or signs of infection (e.g., fever, redness spreading).

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis is supported by clinical findings or imaging. Code I80.213 is specific to bilateral iliac vein involvement; verify no other specified veins are affected to avoid miscoding.
