A written official guideline may not be out yet, but unofficially, coding consultants have said that when the AMA was asked, the AMA presented the question to the ACC, which said an acute example would be ballooning within 90 minutes of first medical contact. This is similar to the industry's door-to-balloon 90-minute goal, which is referenced in AMA's CPT Changes 2013 clinical example for 92941. There’s confusion because ICD-9 uses AMI codes for “specified as acute or with a stated duration of 8 weeks or less.” Until a definition is officially published, checking with the payer is the surest way to match the payer’s understanding of the code.
