ICD-10 Code I82.729 – Chronic embolism and thrombosis of deep veins of unspecified upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.729 – Chronic embolism and thrombosis of deep veins of unspecified upper extremity
What it is
This code identifies a chronic clot or embolus in the deep veins of an upper extremity when the specific arm side is not documented. Use it for a long-standing venous obstruction affecting the deep venous system.
Clinical signs
Typical findings may include arm swelling, pain, heaviness, or visible collateral veins. Clinical features vary; refer to documentation, and confirm that the condition is chronic rather than acute.
When to use this code
Use I82.729 when the record clearly states chronic deep vein thrombosis or chronic embolism in an upper extremity, but does not specify left or right. It may also fit follow-up notes describing persistent, established upper-extremity venous thrombosis. Check documentation if the provider uses mixed acute and chronic language.
Do not use for
Do not use this code for acute upper-extremity DVT, superficial vein thrombosis, or lower-extremity venous thrombosis. If the side is documented, choose the more specific code instead.
Coding tip
Verify that “chronic” is documented and that the thrombosis involves deep veins of an upper extremity before assigning I82.729.
