O87.0 Superficial thrombophlebitis in the puerperium

Name of the Condition

• Superficial Thrombophlebitis in the Puerperium (O87.0)

Summary

Superficial thrombophlebitis in the puerperium refers to inflammation and clot formation in superficial veins during the postpartum period. This condition typically affects the lower extremities and may present with localized pain, redness, and swelling. It is distinct from deep vein thrombosis (DVT) and generally carries a lower risk of serious complications.

Causes

The condition arises from venous stasis, endothelial injury, or hypercoagulability, which are common in the postpartum state. Hormonal changes, reduced mobility, and compression of pelvic veins during pregnancy or delivery can contribute to clot formation in superficial veins.

Risk Factors

• Prolonged immobility or bed rest after delivery.
• History of thromboembolic events or hypercoagulable disorders.
• Obesity or varicose veins.
• Dehydration or inadequate fluid intake.
• Use of certain medications (e.g., hormonal contraceptives, certain antibiotics).

Symptoms

• Localized pain, tenderness, or warmth along a superficial vein.
• Redness or discoloration of the skin over the affected area.
• Swelling or hardening of the vein.
• Mild fever or systemic symptoms in severe cases.

Diagnosis

Diagnosis is primarily clinical, based on physical examination findings of a tender, inflamed superficial vein. Ultrasound imaging may be used to confirm the presence of a thrombus and rule out concurrent deep vein thrombosis. Blood tests are not typically required unless systemic symptoms suggest a more serious condition.

Treatment Options

• Supportive care: Rest, elevation of the affected limb, and warm compresses to reduce discomfort.
• Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain and inflammation; anticoagulants may be considered in high-risk cases or if extension to deep veins is suspected.
• Compression therapy: Graduated compression stockings to improve venous return and reduce swelling.

Prognosis and Follow-Up

Most cases resolve with conservative management within 1–2 weeks. Follow-up is recommended to monitor for symptom improvement and to assess for recurrence or progression to deeper veins. Patients with persistent symptoms or risk factors may require ongoing evaluation.

Complications

• Extension of the thrombus to deeper veins (rare but serious).
• Skin necrosis or ulceration if the affected area becomes severely inflamed.
• Post-thrombotic syndrome (chronic pain or swelling) in rare cases.

Lifestyle & Prevention

• Encourage early mobilization after delivery to promote circulation.
• Maintain adequate hydration and avoid prolonged sitting or standing.
• Use compression garments if varicose veins or prior thrombosis are present.
• Avoid tight clothing that may restrict blood flow.

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, spread, or are accompanied by fever, chills, or difficulty breathing, as these may indicate a more serious condition like sepsis or pulmonary embolism.

Tips for Medical Coders

Document the location of the affected vein (e.g., lower extremity) and any associated symptoms (e.g., pain, redness) to support the diagnosis. Ensure the postpartum context is clearly noted, as this distinguishes the condition from non-puerperal superficial thrombophlebitis. Code O87.0 is specific to the puerperium and should not be used for thrombophlebitis occurring outside this period.
