ICD-10 Code I82.443 – Acute embolism and thrombosis of tibial vein, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.443 – Acute embolism and thrombosis of tibial vein, bilateral
What it is
I82.443 identifies an acute blood clot or embolus in both tibial veins of the lower legs. Use it when documentation specifies bilateral tibial vein involvement and the event is acute.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include leg pain, swelling, tenderness, and sometimes warmth or redness, with imaging used to confirm venous thrombosis.
When to use this code
Use this code when the provider documents acute thrombosis or embolism affecting the tibial veins on both sides. It is appropriate when the record clearly states bilateral tibial vein DVT or equivalent wording. If the laterality or acuity is not specified, check documentation before coding.
Do not use for
Do not use I82.443 for chronic or old thrombosis, or when only one leg is involved. Do not assign it if the clot is in a different venous segment and tibial veins are not documented.
Coding tip
Verify both acuity and bilateral tibial vein location in the assessment, imaging report, or discharge diagnosis before assigning this code.
