I80.01 Phlebitis and thrombophlebitis of superficial vessels of right lower extremity

Name of the Condition

• Phlebitis and Thrombophlebitis of Superficial Vessels of Right Lower Extremity

Summary

Phlebitis and thrombophlebitis of superficial vessels of the right lower extremity involve inflammation of veins near the skin’s surface, often with clot formation. This condition typically causes localized pain, swelling, and visible changes in the affected area. While generally less severe than deep vein involvement, it may still lead to complications if untreated.

Causes

The condition is often triggered by factors that irritate or damage superficial veins, such as intravenous catheter placement, trauma, or infection. Prolonged immobility or underlying clotting disorders can also contribute to clot formation in these vessels.

Risk Factors

• Recent surgery or injury to the lower limbs
• Prolonged sitting or standing
• Varicose veins
• Obesity
• Smoking
• Hormonal changes (e.g., pregnancy, oral contraceptives)
• History of superficial thrombophlebitis

Symptoms

• Pain or tenderness along the affected vein
• Redness or warmth over the vein
• Swelling in the affected area
• Visible hardening or cord-like texture of the vein
• Mild fever (in some cases)

Diagnosis

Diagnosis is typically based on physical examination and clinical history. Ultrasound imaging may be used to confirm clot presence or rule out deeper vein involvement. Blood tests, such as D-dimer, may be ordered to assess clotting activity, though results are often nonspecific.

Treatment Options

• Anticoagulant medications to prevent further clotting
• Anti-inflammatory drugs to reduce pain and swelling
• Compression stockings to improve blood flow
• Warm compresses to alleviate discomfort
• Elevation of the affected limb to reduce swelling

Prognosis and Follow-Up

Most cases resolve with appropriate treatment, though recurrence is possible. Follow-up may include monitoring for symptom improvement and assessing for underlying risk factors. Long-term complications are rare but may include post-thrombotic syndrome or infection.

Complications

• Skin discoloration or pigmentation changes
• Persistent pain or swelling
• Superficial vein damage or scarring
• Rare progression to deep vein thrombosis

Lifestyle & Prevention

• Avoid prolonged immobility; take breaks during travel or sitting
• Maintain a healthy weight
• Quit smoking
• Stay hydrated
• Wear compression stockings if recommended
• Avoid intravenous catheters in affected areas when possible

When to Seek Professional Help

Seek care if symptoms worsen, spread, or include fever, difficulty breathing, or chest pain. These may indicate complications like infection or deep vein thrombosis.

Tips for Medical Coders

Document the specific location (right lower extremity) and confirm superficial vessel involvement. Ensure clinical notes support the diagnosis and exclude deep vein thrombosis or other related conditions. Code I80.01 is specific to the right lower extremity; verify laterality and vessel depth in documentation.
