I80.22 Phlebitis and thrombophlebitis of popliteal vein

Name of the Condition

• Common names: Phlebitis, Thrombophlebitis
• Medical terms: Phlebitis and thrombophlebitis of popliteal vein

Summary

Phlebitis and thrombophlebitis of the popliteal vein involve inflammation and clot formation in the veins located behind the knee. 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 knee area
• 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

• Anticoagulant medications to prevent further clotting
• Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation
• Compression stockings to improve circulation
• In severe cases, surgical removal of the clot may be required

Prognosis and Follow-Up

With appropriate treatment, most patients recover completely. Follow-up care may include monitoring for recurrence and managing underlying risk factors to prevent future episodes.

Complications

• Pulmonary embolism (if the clot travels to the lungs)
• Post-thrombotic syndrome (chronic pain and swelling)
• Skin ulcers or tissue damage due to poor circulation

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Avoid smoking
• Use compression stockings during long periods of sitting or standing
• Stay hydrated and move regularly during travel

When to Seek Professional Help

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

Tips for Medical Coders

Document the specific location (popliteal vein) and whether the condition is acute or chronic. Include details about any contributing factors, such as trauma or immobility, to support accurate coding. Ensure documentation aligns with clinical findings and treatment provided.
