ICD-10 Code I74.8 – Embolism and thrombosis of other arteries (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I74.8 – Embolism and thrombosis of other arteries
What it is
I74.8 identifies embolism or thrombosis in an artery other than the major named sites listed elsewhere. Use it when documentation specifies an arterial clot or blockage but does not name a more specific artery.
Clinical signs
Findings usually reflect reduced arterial blood flow, such as pain, pallor, coolness, or diminished pulses in the affected area. Clinical features vary; refer to documentation.
When to use this code
Use I74.8 when the provider documents arterial embolism or thrombosis in an unspecified peripheral or other artery and no more specific code applies. It also fits cases where the affected artery is named, but that site is not separately classified in ICD-10-CM. Check documentation for laterality and vessel detail when available.
Do not use for
Do not use this code for venous thrombosis, coronary artery thrombosis, or embolism in a more specific artery category. If the record names a different arterial site, code that site instead.
Coding tip
Look for the exact vessel and whether the event is embolic or thrombotic before assigning I74.8.
