ICD-10 Code I82.433 – Acute Embolism and Thrombosis of Popliteal Vein, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.433 – Acute embolism and thrombosis of popliteal vein, bilateral
What it is
This code identifies an acute blood clot or embolus in both popliteal veins, the deep veins behind each knee. It is used when the problem is newly diagnosed and specifically documented as bilateral.
Clinical signs
Typical findings include leg swelling, pain, tenderness, warmth, or a sense of fullness behind the knees. Clinical features vary; refer to documentation, and confirm laterality and acuity in the record.
When to use this code
Use I82.433 when the provider documents acute thrombosis or embolism involving both popliteal veins. The note should support an acute deep vein thrombosis in the popliteal segment, with bilateral involvement clearly stated. If the site, side, or acuity is unclear, check documentation before coding.
Do not use for
Do not use this code for chronic or old DVT, or when thrombosis is in a different vein segment. If bilateral involvement is not documented, you should not assume it.
Coding tip
Verify both acuity and bilateral popliteal location in the provider documentation before assigning I82.433.
