Additional Info
- The term "non-Q MI" is outdated. The modern equivalent is NSTEMI.
- If the diagnosis of ACS is indicated by history and ECG, the diagnosis of NSTEMI may be established if a biomarker of myocardial injury has been released (i.e., troponin elevation). If there is no evidence of biochemical marker release suggestive of myocardial necrosis in a patient with suspected ACS, they may be considered to have experienced unstable angina.
Alternate ICD10s to consider coding instead or in addition
- Myocardial infarction, acute (AMI), NOS
- Myocardial infarction, acute (AMI), transmural (Q-wave) Note: the modern name if STEMI
