Does the standard ICD-10 definition accurately identify STEMI and non-STEMI compared to supplementary ECG codes based on physician chart review?
Standard ICD-10 codes are equivalent to supplementary ECG codes for identifying STEMI and NSTEMI in administrative data.
The standard definition appears equivalent to the definition using supplementary ECG codes to subcategorize patients with acute MI as having STEMI or non-STEMI. These findings may be relevant for the development of later versions of ICD codes.
