I80.23 Phlebitis and thrombophlebitis of tibial vein

Name of the Condition

• Phlebitis and Thrombophlebitis of Tibial Vein

Summary

Phlebitis and thrombophlebitis of the tibial vein involve inflammation and clot formation in the tibial veins, which are deep veins in the lower leg. 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 calf
• Swelling in the affected leg
• Warmth and redness over the affected vein
• 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 considered.

Prognosis and Follow-Up

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

Complications

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

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Avoid smoking
• Stay hydrated
• Use compression stockings if recommended
• Follow up on underlying conditions that increase clotting risk

When to Seek Professional Help

Seek medical attention if you experience sudden leg pain, swelling, redness, or warmth, especially if accompanied by shortness of breath or chest pain, as these may indicate a serious complication.

Tips for Medical Coders

When coding I80.23, ensure documentation specifies the tibial vein as the site of phlebitis and thrombophlebitis. Verify that the condition is clearly differentiated from other deep vein thromboses (e.g., femoral or popliteal veins) to support accurate code assignment.
