ICD-10 Code I82.60 – Acute embolism and thrombosis of unspecified veins of upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.60 – Acute embolism and thrombosis of unspecified veins of upper extremity
What it is
This code identifies a sudden blood clot or embolus in a vein of the upper extremity when the specific vein is not documented. It applies to an acute event affecting the arm or shoulder venous system.
Clinical signs
Typical findings include arm swelling, pain, tenderness, warmth, or visible superficial venous distention. Clinical features vary; refer to documentation for imaging or provider confirmation of venous thrombosis.
When to use this code
Use I82.60 when the provider documents acute embolism or thrombosis in an unspecified upper-extremity vein and no more specific vein is named. This may fit emergency, inpatient, or outpatient records with confirmed upper-arm venous clotting. If the record later identifies a specific vein, code that more precise diagnosis instead.
Do not use for
Do not use this code for chronic or old thrombosis, or when the clot is in a specified vein already documented elsewhere. Check documentation if the record describes superficial thrombophlebitis or a different vascular site.
Coding tip
Code only when the documentation clearly supports an acute upper-extremity venous clot and the vein remains unspecified.
