Reader Question:

413.9 Applies to Angina After Infarction, Too

Question: Should I report 411.0 for postinfarction angina?

Answer: No, you should report the appropriate angina code for postinfarction angina, such as 413.9 (Other and unspecified angina pectoris). Reporting postinfarction angina indicates the patient has chest pain, affecting care, following a myocardial infarction.

In contrast, 411.0 (Postmyocardial infarction syndrome) represents Dressler’s syndrome. Features of the syndrome include pericarditis, lung inflammation, pleural effusion, fever, and pain in the area of the heart and lungs, among others. It may appear days or months after the infarction.

ICD-10: ICD-10 crosses 413.9 to I20.8 (Other forms of angina pectoris) and I20.9 (Angina pectoris, unspecified). There are also a number of I25.- codes (Chronic ischemic heart disease) that combine angina and atherosclerosis diagnoses. Code 411.0 crosses to I24.1 (Dressler’s syndrome).
