Atheroembolism (I75)

ICD-10 code I75 encompasses atheroembolism, a condition involving cholesterol or atheromatous emboli blocking arteries and affecting blood flow. These codes specify the location of the embolism, such as upper or lower extremities, kidneys, or other sites.

The section includes codes like I75.0 for atheroembolism of extremities, with more detailed subcodes for right, left, or bilateral involvement of upper (I75.01 series) and lower limbs (I75.02 series). For example, I75.011 addresses atheroembolism specifically in the right upper extremity, commonly called "embolism of artery of right upper limb." When the exact limb isn't specified, codes like I75.019 cover unspecified upper extremity cases, often referred to as "cholesterol embolus syndrome." Additional codes such as I75.81 apply to embolism in the kidney ("renal artery embolism"), while I75.89 covers other uncommon sites, including digital arteries or cerebral vessels. These codes guide healthcare professionals and coders in accurately classifying atheroembolism by location to support appropriate diagnosis and treatment documentation.
