BA42.1 Subsequent myocardial infarction, non-ST elevation myocardial infarction International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2025-01 Extension or recurrent myocardial infarction. For morbidity coding, this category should be assigned for infarction of any myocardial site, occurring within 4 weeks (28 days) from onset of a previous infarction. This most commonly results from severe obstruction, but not total occlusion, of the culprit coronary artery.
postcoordination Add Stem and/or Extension codes to form a cluster code which adds detail to the condition.
