ICD-10 Code I82.553 – Chronic embolism and thrombosis of peroneal vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.553 – Chronic embolism and thrombosis of peroneal vein, bilateral
What it is
This code identifies a chronic blood clot or embolic obstruction in both peroneal veins, which are deep veins in the lower legs. It indicates a long-standing venous blockage rather than an acute event.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include chronic leg swelling, pain, tenderness, skin discoloration, or prior imaging showing persistent peroneal vein thrombosis.
When to use this code
Use this code when the record clearly documents chronic embolism or thrombosis affecting both peroneal veins. It is appropriate for follow-up visits, history review, or ongoing management when the condition remains present. Check documentation for laterality and chronicity.
Do not use for
Do not use this code for acute deep vein thrombosis, superficial vein thrombosis, or unspecified lower-extremity venous clotting. If the chart does not confirm bilateral peroneal vein involvement, check documentation.
Coding tip
Verify both chronic status and bilateral laterality in the provider note or imaging report before assigning I82.553.
