ICD-10 Code I82.511 – Chronic embolism and thrombosis of right femoral vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.511 – Chronic embolism and thrombosis of right femoral vein
What it is
I82.511 identifies a chronic clot or embolic obstruction in the right femoral vein. Use it when the record shows an ongoing, longstanding venous blockage in that specific leg vein.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include persistent unilateral leg swelling, pain, heaviness, or prior imaging showing chronic venous thrombosis in the right femoral vein.
When to use this code
Use this code when the provider documents chronic embolism, chronic thrombosis, or chronic venous occlusion of the right femoral vein. It may also fit follow-up visits for a known chronic clot if the condition remains active and documented.
Confirm laterality and chronicity in the note or imaging report. If the record only says “DVT” without specifying chronic status or right femoral location, check documentation before coding.
Do not use for
Do not use I82.511 for acute deep vein thrombosis, unspecified lower-extremity thrombosis, or clotting in a different vein. Check documentation if the site or chronic nature is unclear.
Coding tip
Match the code to both chronicity and right-sided femoral location; if either element is missing, query or review the source record.
