ICD-10 Code I82.453 – Acute embolism and thrombosis of peroneal vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.453 – Acute embolism and thrombosis of peroneal vein, bilateral
What it is
This code identifies an acute blood clot or embolus in both peroneal veins, which are deep veins in the lower legs. Use it when documentation specifies bilateral peroneal vein involvement.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include leg pain, swelling, tenderness, or a confirmed deep vein thrombosis on imaging affecting both peroneal veins.
When to use this code
Use I82.453 when the provider documents acute embolism and thrombosis in the peroneal veins on both sides. It fits confirmed bilateral distal deep vein thrombosis, including imaging-supported cases.
Choose this code only when the record clearly states acuity and bilateral peroneal vein involvement. If the note names a different deep vein, or laterality is missing, check documentation.
Do not use for
Do not use this code for chronic thrombosis, superficial vein thrombosis, or clots in veins other than the peroneal veins. If the site or laterality is unclear, check documentation.
Coding tip
Verify that both acuity and bilateral peroneal vein location are documented before assigning I82.453.
