I70 Atherosclerosis

ICD-10-CM category I70 sits in Chapter 9 (Diseases of the circulatory system, I00-I99). It contains 246 billable codes for FY2027, effective October 1, 2026 to September 30, 2027. Always code to the most specific code available: a code with more characters that describes the diagnosis more precisely takes priority over a shorter one.
