ICD-10 Code I82.592 – Chronic embolism and thrombosis of other specified deep vein of left lower extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.592 – Chronic embolism and thrombosis of other specified deep vein of left lower extremity
What it is
This code identifies a long-standing clot or embolus in a deep vein of the left lower extremity that is not one of the specifically named veins. Use it when the record documents chronic venous obstruction on the left side.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note persistent leg swelling, pain, heaviness, or prior imaging showing chronic thrombus or venous scarring in a deep vein.
When to use this code
Use this code when the provider documents chronic thrombosis or chronic embolism in an other specified deep vein of the left lower extremity. It fits cases where the vein is deep, left-sided, and not captured by a more specific ICD-10 option. If the note only says “history of DVT” or does not specify chronicity, check documentation.
Do not use for
Do not use this code for acute DVT, superficial vein thrombosis, or thrombosis in a specifically named deep vein when a more precise code is available. Check documentation if laterality or chronic status is unclear.
Coding tip
Confirm both chronicity and left lower-extremity location before assigning I82.592.
