ICD-10 Code I82.452 – Acute embolism and thrombosis of left peroneal vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.452 – Acute embolism and thrombosis of left peroneal vein
What it is
This code identifies an acute blood clot or embolus in the left peroneal vein, a deep vein in the lower leg. Use it when documentation specifies the left side and the event is acute.
Clinical signs
Typical findings include unilateral calf pain, swelling, tenderness, warmth, or redness, though clinical features vary; refer to documentation. Imaging is usually used to confirm the clot location and acuity.
When to use this code
Use I82.452 when the record clearly states acute embolism or thrombosis in the left peroneal vein. It fits confirmed deep vein thrombosis limited to that vein, or documentation that names the peroneal vein on the left. If acuity, laterality, or vein site is unclear, check documentation.
Do not use for
Do not use this code for chronic or historical thrombosis, or for clotting in a different vein. If the chart only says DVT without specifying the left peroneal vein, this code is not supported.
Coding tip
Confirm both acuity and laterality in the provider note before assigning I82.452.
