ICD-10 Code I82.701 – Chronic embolism and thrombosis of unspecified veins of right upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.701 – Chronic embolism and thrombosis of unspecified veins of right upper extremity
What it is
This code identifies a long-standing blood clot or embolic obstruction in an unspecified vein of the right upper extremity. Use it when the record confirms chronic venous thrombosis or embolism but does not specify a named vein.
Clinical signs
Findings may include arm swelling, pain, heaviness, or visible superficial venous changes. Clinical features vary; refer to documentation, and confirm that the condition is described as chronic rather than acute.
When to use this code
Use I82.701 when the provider documents chronic embolism or thrombosis affecting an unspecified vein in the right arm. It is appropriate when laterality is clear, chronicity is stated, and the exact vein is not identified. If the note describes a different extremity or a specific vein, code that documentation instead.
Do not use for
Do not use this code for acute venous thrombosis, superficial thrombophlebitis, or thrombosis in a specified vein when the record names one. Check documentation if the side, chronicity, or vessel location is unclear.
Coding tip
Verify three elements in the note: chronic, right upper extremity, and unspecified vein; if any element is missing, check documentation.
