ICD-10 Code I82.513 – Chronic embolism and thrombosis of femoral vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.513 – Chronic embolism and thrombosis of femoral vein, bilateral
What it is
I82.513 identifies a long-standing blood clot or embolic obstruction in both femoral veins. Use it when documentation specifies chronic involvement of the bilateral femoral veins.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include leg swelling, pain, heaviness, or venous stasis changes, but the code depends on documented chronic bilateral femoral vein disease.
When to use this code
Use this code when the provider documents chronic thrombosis or embolism affecting both femoral veins. It also fits follow-up notes that clearly state persistent bilateral femoral vein clotting rather than an acute event.
If the record only says “DVT” without chronicity or location, check documentation. Confirm that both sides are involved and that the femoral vein is the site being coded.
Do not use for
Do not use it for acute femoral vein thrombosis, unspecified DVT, or clotting in a different vein location. Check documentation if the record does not clearly support chronic bilateral femoral involvement.
Coding tip
Verify both laterality and chronic status in the provider note before assigning I82.513.
