About ICD-9-CM 414.8
414.8 is an ICD-9-CM diagnosis code for other specified forms of chronic ischemic heart disease. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as I25.5 (Ischemic cardiomyopathy), I25.89 (Other forms of chronic ischemic heart disease) and I25.9 (Chronic ischemic heart disease, unspecified). All of these are approximate matches, so review the record to pick the right one.
