ICD-10 Code I82.533 – Chronic embolism and thrombosis of popliteal vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.533 – Chronic embolism and thrombosis of popliteal vein, bilateral
What it is
This code identifies a long-standing blood clot or embolic obstruction in both popliteal veins, which are located behind the knees. Use it when the record documents chronic involvement on both sides.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include leg swelling, pain, heaviness, or venous insufficiency changes, but the diagnosis should be supported by imaging or specialist assessment.
When to use this code
Use I82.533 when the provider clearly documents chronic thrombosis or chronic embolism affecting both popliteal veins. It may appear in follow-up notes, vascular consultations, or imaging reports describing persistent bilateral disease. Check documentation if laterality or chronicity is unclear.
Do not use for
Do not use this code for acute DVT, superficial thrombophlebitis, or thrombosis in a different venous location. If the note does not specify bilateral popliteal involvement, check documentation.
Coding tip
Confirm both chronicity and bilateral popliteal location in the source record before assigning I82.533.
