ICD-10 Code I80.232 – Phlebitis and thrombophlebitis of left tibial vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I80.232 – Phlebitis and thrombophlebitis of left tibial vein
What it is
I80.232 identifies inflammation of a vein in the left tibial region with associated clot formation. Use it when the documented diagnosis is phlebitis or thrombophlebitis of the left tibial vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include localized leg pain, swelling, tenderness, warmth, or redness along the affected vein, with diagnosis supported by clinical assessment or imaging.
When to use this code
Use this code when the provider documents phlebitis or thrombophlebitis specifically involving the left tibial vein. It is appropriate for confirmed acute or subacute venous inflammation with thrombosis in that location. Check documentation if the record only states deep vein thrombosis without site detail.
Do not use for
Do not use it for thrombophlebitis in another leg vein or for superficial vein disease unless the tibial vein is named. If the site is unclear or only “left leg DVT” is documented, check documentation.
Coding tip
Verify laterality and exact vein location before assigning I80.232.
