ICD-10 Code I82.54 – Chronic embolism and thrombosis of tibial vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.54 – Chronic embolism and thrombosis of tibial vein
What it is
This code identifies a chronic clot or embolic obstruction in a tibial vein of the lower leg. Use it when documentation specifies the condition is chronic and involves the tibial vein.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include persistent leg swelling, discomfort, or venous insufficiency signs, but you should code only what is documented.
When to use this code
Use I82.54 when the provider documents chronic embolism or thrombosis in a tibial vein, including ongoing or residual clot disease. It may also apply when imaging or specialist notes clearly identify chronic tibial vein involvement. If the record does not specify chronicity or the vein location, check documentation.
Do not use for
Do not use this code for acute tibial vein thrombosis or for thrombosis in a different leg vein. If the documentation is nonspecific, or the condition is elsewhere in the venous system, choose the appropriate code instead.
Coding tip
Confirm both chronic status and tibial vein location in the note before assigning I82.54.
