ICD-10 Code I82.612 – Acute embolism and thrombosis of superficial veins of left upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.612 – Acute embolism and thrombosis of superficial veins of left upper extremity
What it is
This code identifies a new clot or embolus in the superficial veins of the left arm. It refers to a problem in veins close to the skin, not the deep venous system.
Clinical signs
Typical findings include localized pain, tenderness, swelling, warmth, or a palpable cord along a superficial vein. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute embolism or thrombosis in a superficial vein of the left upper extremity. It fits cases such as superficial thrombophlebitis of the left arm when the record clearly supports an acute clot. Check documentation if laterality, acuity, or vein type is unclear.
Do not use for
Do not use it for deep vein thrombosis of the arm or for unspecified upper-extremity vein thrombosis. Do not assign it when the note only says “history of” clot or when the affected side is not documented.
Coding tip
Verify that the record states both acute involvement and left-sided superficial vein disease before assigning I82.612.
