I80.242 Phlebitis and thrombophlebitis of left peroneal vein

Name of the Condition

• Phlebitis and Thrombophlebitis of Left Peroneal Vein

Summary

Phlebitis and thrombophlebitis of the left peroneal vein involve inflammation and clot formation in the left peroneal vein, a deep vein 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 left calf
• Swelling in the left lower 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, such as compression stockings. In severe cases, thrombolytic therapy or surgical intervention may be considered.

Prognosis and Follow-Up

With prompt treatment, the prognosis is generally favorable, but follow-up care is important to monitor for recurrence or complications. Regular check-ups and adherence to prescribed therapies can help manage the condition effectively.

Complications

Potential complications include deep vein thrombosis (DVT) progression, pulmonary embolism, post-thrombotic syndrome (chronic pain and swelling), or infection of the affected vein.

Lifestyle & Prevention

• Maintain regular physical activity to promote circulation
• Avoid prolonged immobility; take breaks during travel or sedentary work
• Stay hydrated and avoid smoking
• Manage weight and underlying health conditions
• Follow post-procedure care instructions if catheter use is involved

When to Seek Professional Help

Seek medical attention if you experience sudden, severe 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 I80.242, ensure documentation specifies the left peroneal vein and confirms the presence of both inflammation (phlebitis) and clot formation (thrombophlebitis). Verify laterality and anatomical specificity to avoid miscoding.
