Heads up:this is a parent code. It's typically not directly billable — you need to drill down to a more specific child code (one with additional digits) to use on a claim.

How coders use this code
ICD-10-CM I23 is a category (header) for certain current complications following st elevation (stemi) and non-st elevation (nstemi) myocardial infarction (within the 28 day period). It is generally not reported directly on a claim — coders drill down to a more specific child code (one with additional characters) that matches the documentation. Use the related codes below to find the billable code that fits, and verify against the annual NCHS/CMS guidelines.
