ICD-10 Code I82.6 – Acute embolism and thrombosis of veins of upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.6 – Acute embolism and thrombosis of veins of upper extremity
What it is
I82.6 identifies an acute clot or embolus in a vein of the upper extremity, such as the arm, shoulder, or related venous structures. Use it when the record documents a new or sudden venous thrombosis in that location.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include arm swelling, pain, tenderness, warmth, or visible superficial venous distention, with imaging or other clinical evidence supporting venous thrombosis.
When to use this code
Use I82.6 when the provider documents acute embolism or thrombosis affecting veins of the upper extremity. It fits encounters where the diagnosis is confirmed, suspected as acute, or clearly described in the assessment. Check documentation if the record does not specify the vein or acuity.
Do not use for
Do not use this code for chronic or old thrombosis, or for arterial occlusion. If the clot is in a lower extremity or another venous site, select the more specific documented code.
Coding tip
Look for the words acute, embolism, or thrombosis and confirm the upper-extremity location before assigning I82.6.
