ICD-10 Code I82.531 – Chronic embolism and thrombosis of right popliteal vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.531 – Chronic embolism and thrombosis of right popliteal vein
What it is
This code identifies a chronic blood clot or embolus in the right popliteal vein behind the knee. Use it when documentation clearly states the condition is chronic and involves the right side.
Clinical signs
Findings may include persistent leg swelling, discomfort, or venous congestion in the affected limb. Clinical features vary; refer to documentation, imaging, or vascular assessment when available.
When to use this code
Use I82.531 when the provider documents chronic thrombosis or chronic embolism of the right popliteal vein. It also applies when follow-up notes confirm an established clot in that vein and do not describe it as acute or unspecified.
If the record only says “DVT” without chronicity or laterality, check documentation before assigning this code. Make sure the right popliteal vein is specifically identified.
Do not use for
Do not use this code for acute thrombosis, unspecified venous thrombosis, or clots in a different vein. Check documentation if the side or chronic status is unclear.
Coding tip
Verify both chronicity and laterality in the provider note before coding I82.531.
