I87.033 Postthrombotic syndrome with ulcer and inflammation of bilateral lower extremity

Name of the Condition

• Postthrombotic syndrome with ulcer and inflammation of bilateral lower extremity (I87.033)

Summary

Postthrombotic syndrome with ulcer and inflammation of bilateral lower extremity is a chronic complication of deep vein thrombosis (DVT) characterized by venous insufficiency, skin ulceration, and inflammation affecting both lower limbs. It results from damage to vein valves and walls, leading to impaired blood flow, persistent symptoms, and tissue breakdown in both legs.

Causes

The condition is caused by residual damage to veins following a DVT, which impairs venous return and causes chronic venous hypertension. This damage leads to skin breakdown, ulcer formation, and inflammatory changes in both lower extremities.

Risk Factors

• History of deep vein thrombosis (DVT)
• Severe or recurrent DVT episodes
• Lack of anticoagulation during acute DVT
• Prolonged immobility or bed rest
• Obesity
• Older age
• Female gender (higher prevalence)

Symptoms

• Chronic leg pain or aching
• Persistent swelling (edema) in both legs
• Skin discoloration (hyperpigmentation)
• Heaviness or fatigue in the legs
• Varicose veins or visible venous prominence
• Open skin ulcer (typically on the lower leg)
• Inflammation (e.g., redness, warmth, or tenderness around the ulcer)

Diagnosis

Diagnosis is based on clinical evaluation, including symptom assessment and physical examination. Duplex ultrasound may be used to assess vein function and detect residual thrombus or valve damage. Documentation should specify bilateral involvement and the presence of ulceration and inflammation.

Treatment Options

Treatment focuses on managing venous insufficiency and promoting ulcer healing. Options may include compression therapy, leg elevation, wound care, and medications to reduce inflammation or pain. Severe cases may require surgical or endovascular interventions.

Prognosis and Follow-Up

Prognosis depends on the severity of venous damage and adherence to treatment. Chronic symptoms often persist, but management can improve quality of life. Regular follow-up is important to monitor ulcer healing and adjust therapy as needed.

Complications

• Chronic non-healing ulcers
• Infection of skin ulcers
• Progression of venous insufficiency
• Reduced mobility due to pain or swelling

Lifestyle & Prevention

• Maintain a healthy weight to reduce venous pressure
• Avoid prolonged immobility; take breaks to move legs
• Use compression stockings as recommended
• Elevate legs when resting to reduce swelling
• Stay active with low-impact exercises (e.g., walking)

When to Seek Professional Help

Seek care if symptoms worsen, ulcers increase in size or pain, or signs of infection (e.g., fever, increased redness) develop. Prompt evaluation is needed for new or worsening swelling, pain, or skin changes.

Tips for Medical Coders

Document the bilateral nature of the condition, ulceration, and inflammation clearly. Ensure clinical notes specify both lower extremities are affected to support the I87.033 code. Include details on ulcer location, size, and inflammatory signs for accurate coding.
