ICD-10 Code I82.53 – Chronic embolism and thrombosis of popliteal vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.53 – Chronic embolism and thrombosis of popliteal vein
What it is
I82.53 identifies a chronic blood clot or embolic blockage in the popliteal vein behind the knee. Use it when the record clearly describes the condition as chronic and involving that vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note persistent leg swelling, discomfort, venous congestion, or prior deep vein thrombosis affecting the popliteal vein.
When to use this code
Use this code when the provider documents chronic embolism or thrombosis in the popliteal vein, including follow-up visits for a known longstanding clot. It may also fit when imaging or specialist notes confirm chronic occlusion in that location. Check documentation if the term “acute” or another vein is used.
Do not use for
Do not use it for acute popliteal vein thrombosis or for superficial venous disease. If the record names a different deep vein or does not specify chronicity, verify the documentation.
Coding tip
Code the vessel and chronic status exactly as documented, and confirm laterality or acuity when the note is unclear.
