ICD-10 Code I82.593 – Chronic embolism and thrombosis of other specified deep vein of lower extremity, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.593 – Chronic embolism and thrombosis of other specified deep vein of lower extremity, bilateral
What it is
This code identifies a long-standing clot or embolic blockage in specified deep veins of both lower extremities. Use it when the documentation clearly states chronic thrombosis or chronic embolism affecting bilateral deep veins.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings may include persistent leg swelling, heaviness, pain, or venous insufficiency related to prior deep vein thrombosis.
When to use this code
Use I82.593 when the provider documents chronic embolism and thrombosis in other specified deep veins of both legs. It fits follow-up encounters for an established bilateral condition, not a new acute event. If the record does not specify chronicity or bilateral involvement, check documentation.
Do not use for
Do not use this code for acute deep vein thrombosis, superficial vein thrombosis, or unspecified lower-extremity venous thrombosis. If the site or chronic status is unclear, check documentation.
Coding tip
Confirm both “chronic” and “bilateral” are documented before assigning I82.593.
