ICD-10 Code I82.532 – Chronic embolism and thrombosis of left popliteal vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.532 – Chronic embolism and thrombosis of left popliteal vein
What it is
I82.532 identifies a chronic blood clot or embolic blockage in the left popliteal vein, the large vein behind the knee. Use it when the condition is longstanding and documented as affecting the left side.
Clinical signs
Clinical features may include persistent leg swelling, pain, heaviness, or skin changes in the affected limb. Documentation may also note a chronic deep vein thrombosis or residual venous obstruction; clinical features vary, refer to documentation.
When to use this code
Use this code when the provider documents chronic embolism, chronic thrombosis, or chronic DVT of the left popliteal vein. It is appropriate for follow-up encounters when the clot is no longer acute but remains clinically relevant. Check documentation for laterality and chronicity.
Do not use for
Do not use it for acute left popliteal vein thrombosis or for clotting in another vein location. If the record does not clearly state chronicity or left-sided involvement, check documentation.
Coding tip
Verify both “chronic” and “left popliteal vein” in the provider note before assigning I82.532.
