ICD-10 Code I82.7 – Chronic embolism and thrombosis of veins of upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.7 – Chronic embolism and thrombosis of veins of upper extremity
What it is
I82.7 identifies a long-standing clot or embolic blockage in a vein of the upper extremity, such as the arm or shoulder region. Use it when documentation clearly states the condition is chronic rather than acute.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings may include persistent arm swelling, venous discomfort, or collateral vein formation, but the record should support chronic venous obstruction.
When to use this code
Use this code when the provider documents chronic embolism or thrombosis in a vein of the upper extremity. It may also fit follow-up visits for an established chronic clot, as long as the diagnosis remains active and specific.
If laterality or the exact vein is documented, code to the highest specificity available. Check documentation when the note only says “history of clot” or does not clearly distinguish acute from chronic.
Do not use for
Do not use I82.7 for acute upper-extremity thrombosis or for superficial vein thrombosis unless the documentation specifically supports this code. Do not assign it when the record only mentions suspected clot.
Coding tip
Confirm that “chronic” is explicitly documented and that the thrombosis involves an upper-extremity vein before assigning I82.7.
