I24.0 vs I25.1
I24.0 (Acute coronary thrombosis not resulting in myocardial infarction) compared with I25.1 (Atherosclerotic heart disease of native coronary artery), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. I24.0 carries an Excludes1 note covering I25.1: “atherosclerotic heart disease (I25.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
