About coding Postinfarction pericarditis
The ICD-10-CM code for Postinfarction pericarditis is I24.1 (Dressler's syndrome).
Within I24 (other acute ischemic heart diseases), I24.1 is specifically for Dressler's syndrome. Related codes cover acute coronary thrombosis not resulting in myocardial infarction (I24.0), other forms of acute ischemic heart disease (I24.8) and acute ischemic heart disease, unspecified (I24.9).
Don't report I24.1 together with the conditions in its Excludes1 note: postinfarction angina (I23.7).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

- postinfarction angina (I23.7)
