I80.212 Phlebitis and thrombophlebitis of left iliac vein

Name of the Condition

• Phlebitis and Thrombophlebitis of Left Iliac Vein

Summary

Phlebitis and thrombophlebitis of the left iliac vein involve inflammation and clot formation in the left iliac vein, a large deep vein 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
• Swelling in the left leg
• Warmth and redness over the affected area
• Visible hardening or cord-like texture of the vein
• 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 often 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
• Recurrent blood clots

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Avoid smoking
• Follow prescribed anticoagulant therapy as directed
• Use compression stockings if recommended

When to Seek Professional Help

Seek immediate medical attention if you experience sudden leg swelling, severe pain, shortness of breath, or chest pain, as these may indicate a serious complication.

Tips for Medical Coders

When coding I80.212, ensure documentation specifies the left iliac vein and confirms the presence of both inflammation (phlebitis) and clot formation (thrombophlebitis). Verify that the condition is not better described by another code and that laterality (left) is clearly documented.
