Key result
Current standard ICD10 codes are insufficient to clearly distinguish between ST elevation and non-ST elevation myocardial infarction, though codes I21.0-I21.3, I22.0, I22.1, and I22.8 best identify STEMI cases.
Why the study?
Are ICD10 codes sufficient to distinguish between STEMI and NSTEMI in hospital administrative data?
Observational (n=716,317)
Yes
Are ICD10 codes sufficient to distinguish between STEMI and NSTEMI in hospital administrative data?
Sole reliance on ICD10 codes is insufficient to accurately distinguish between STEMI and NSTEMI in administrative datasets.
No takes yet. Share an insight, caveat, or question.
Sole reliance on ICD-10 codes risks MI misclassification in administrative data; leaves open validation with clinical records or refined algorithms.
Alexandrescu et al. (2013) conducted an observational in Acute myocardial infarction (n=716,317). ICD10 AMI subcategory codes was evaluated on Proportion of AMI cases undergoing coronary angioplasty on the same day or same/next day of hospital admission (proxy for STEMI). Current standard ICD10 codes are insufficient to clearly distinguish between ST elevation and non-ST elevation myocardial infarction, though codes I21.0-I21.3, I22.0, I22.1, and I22.8 best identify STEMI cases.
