ICD-10 Code I23.7 – Postinfarction angina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I23.7 – Postinfarction angina
What it is
I23.7 identifies angina that develops after a recent myocardial infarction. Use it for ischemic chest pain documented as occurring in the post-infarction period.
Clinical signs
Clinical features vary; refer to documentation. Typical records note recurrent chest discomfort or ischemic symptoms after an MI, with provider assessment linking the pain to the recent infarction.
When to use this code
Use I23.7 when the clinician documents angina as a complication of a recent heart attack. It is appropriate when the record clearly states postinfarction angina, post-MI angina, or similar wording. Check documentation if the chest pain is not explicitly tied to the infarction.
Do not use for
Do not use this code for uncomplicated chest pain, stable angina, or angina unrelated to a recent MI. If the documentation does not show a post-infarction relationship, choose a different code.
Coding tip
Confirm that the provider documents the angina as a post-MI complication before assigning I23.7.
