ICD-10 Code I82.A11 – Acute embolism and thrombosis of right axillary vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.A11 – Acute embolism and thrombosis of right axillary vein
What it is
This code identifies a new blood clot or embolus in the right axillary vein, a deep vein in the upper arm near the shoulder. Use it when documentation specifies the right side and the event is acute.
Clinical signs
Typical findings include arm swelling, pain, tenderness, and sometimes visible superficial veins. Clinical features vary; refer to documentation and imaging or provider diagnosis when available.
When to use this code
Use I82.A11 when the record clearly states acute thrombosis or embolism of the right axillary vein. It is appropriate for confirmed upper-extremity deep vein thrombosis involving that vein, including cases documented on ultrasound or by specialist assessment.
Do not use for
Do not use this code for chronic, old, or unspecified upper-extremity clots, or for thrombosis in a different vein. Check documentation if the side, acuity, or vein location is not clearly stated.
Coding tip
Verify both acuity and laterality before assigning the code.
