Subsequent ST elevation (STEMI) myocardial infarction of other sites
- I22.8 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
- Short description: Subsequent STEMI of sites
- The 2025 edition of ICD-10-CM I22.8 became effective on October 1, 2024.
- This is the American ICD-10-CM version of I22.8 – other international versions of ICD-10 I22.8 may differ.

- Subsequent transmural (Q wave) myocardial infarction (acute)(of) lateral (wall) NOS
- Subsequent posterior (true) transmural (Q wave) myocardial infarction (acute)
- Subsequent posterobasal transmural (Q wave) myocardial infarction (acute)
- Subsequent posterolateral transmural (Q wave) myocardial infarction (acute)
