Guidelines › Subsequent acute myocardial infarction
Subsequent acute myocardial infarction
Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.
Guidelines I.C.9.e.4
“Do not assign code I22 for subsequent myocardial infarctions other than type 1 or unspecified. For subsequent type 2 AMI assign only code I21.A1. For subsequent type 4 or type 5 AMI, assign only code I21.A9.”
“Codes from category I22 should only be assigned if both the initial and subsequent myocardial infarctions are type 1 or unspecified.”
Where this applies
The Guidelines are the authority for assigning codes, and following them is required under HIPAA. This page quotes them for convenience and is not a substitute for the official document. See the Terms and Disclaimer.
