I80.201 Phlebitis and thrombophlebitis of unspecified deep vessels of right lower extremity

Name of the Condition

• Phlebitis and Thrombophlebitis of Unspecified Deep Vessels of Right Lower Extremity

Summary

Phlebitis and thrombophlebitis of unspecified deep vessels of the right lower extremity involve inflammation and clot formation in deep veins of the right leg, excluding the femoral and popliteal veins. 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 affected limb
• Swelling in the lower extremity
• 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 risk factors to prevent future episodes.

Complications

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

Lifestyle & Prevention

• Stay active and avoid prolonged immobility
• Maintain a healthy weight
• Quit smoking
• Use compression stockings during long periods of sitting or standing
• Stay hydrated and avoid dehydration

When to Seek Professional Help

Seek medical attention if you experience sudden swelling, pain, or redness in the right lower extremity, especially if accompanied by shortness of breath or chest pain.

Tips for Medical Coders

Document the specific location (right lower extremity) and vessel type (unspecified deep vessels) to support accurate coding. Ensure clinical documentation confirms the absence of femoral or popliteal vein involvement to align with the code's specificity.
