ICD-10 Code I82.493 – Acute embolism and thrombosis of other specified deep vein of lower extremity, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.493 – Acute embolism and thrombosis of other specified deep vein of lower extremity, bilateral
What it is
This code identifies an acute blood clot or embolus in other specified deep veins of both lower extremities. Use it when the provider documents bilateral deep vein involvement that is not captured by a more specific lower-extremity DVT code.
Clinical signs
Clinical features vary; refer to documentation. Common findings in deep vein thrombosis include leg pain, swelling, warmth, tenderness, or asymmetry, but the diagnosis should be supported by provider assessment or imaging.
When to use this code
Use I82.493 when the record clearly states acute embolism and thrombosis in other specified deep veins of both legs. It is appropriate for confirmed bilateral lower-extremity DVT when the involved vein is not listed elsewhere in the code set. Check documentation if the laterality or vein location is unclear.
Do not use for
Do not use this code for superficial thrombophlebitis, chronic or old thrombosis, or DVT in a different anatomic site. If the documentation identifies a more specific vein or a different laterality, code that instead.
Coding tip
Verify both acute status and bilateral involvement in the provider note before assigning I82.493.
