I87.013 Postthrombotic syndrome with ulcer of bilateral lower extremity

Name of the Condition

• Postthrombotic syndrome with ulcer of bilateral lower extremity (I87.013)

Summary

Postthrombotic syndrome with ulcer of bilateral lower extremity is a chronic complication of deep vein thrombosis (DVT) affecting both lower limbs, characterized by venous insufficiency and the presence of skin ulcers. It results from damage to vein valves and walls, leading to impaired blood flow and persistent symptoms, including ulceration 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 and ulcer formation in severe cases, affecting both lower extremities.

Risk Factors

• History of deep vein thrombosis (DVT) in both lower extremities
• 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 in both lower extremities
• Persistent swelling (edema) in both legs
• Skin discoloration (hyperpigmentation) on both legs
• Heaviness or fatigue in the legs
• Varicose veins or visible venous prominence
• Open skin ulcers on both lower extremities

Diagnosis

Diagnosis is based on clinical evaluation, including symptom assessment and physical examination of both lower extremities. Duplex ultrasound may be used to assess vein function and detect residual thrombus or valve damage. The presence of ulcers on both legs confirms the complication.

Treatment Options

• Compression therapy (e.g., specialized stockings)
• Leg elevation and exercise
• Wound care for ulcers
• Medications to manage pain or swelling
• Surgical or endovascular interventions for severe cases

Prognosis and Follow-Up

Prognosis depends on the severity of venous damage and adherence to treatment. Regular follow-up is important to monitor ulcer healing and manage symptoms. Early intervention may improve outcomes.

Complications

• Chronic pain and disability
• Recurrent ulcers
• Infection of ulcers
• Venous stasis dermatitis
• Deep vein thrombosis recurrence

Lifestyle & Prevention

• Maintain a healthy weight
• Stay active and avoid prolonged immobility
• Use compression stockings as recommended
• Elevate legs when resting
• Avoid smoking, which can worsen venous health

When to Seek Professional Help

Seek medical attention if you experience:

• New or worsening leg swelling
• Increased pain or discomfort
• Signs of infection (e.g., redness, pus)
• Ulcers that do not heal or worsen

Tips for Medical Coders

Document the bilateral nature of the ulcers and confirm the history of DVT. Ensure clinical notes specify the presence of ulcers on both lower extremities to support the code. Include details on ulcer location, size, and any associated symptoms for accurate coding.
