READER QUESTIONS:

Mind Your Digits When Coding For MI

Question: When a patient is receiving care for a myocardial infarction, 410.x (Acute myocardial infarction), how do I know which fifth digit to report?


Texas Subscriber


Answer: The fifth digits indicate the episode of care--in other words the encounters with the health care system. '2' is usually the fifth digit for home health because we are the subsequent episode of care.

Example: The hospital may be the initial encounter with the health system when a patient has had an MI. Any subsequent encounter, whether it be rehab or home health, is a subsequent encounter and should be coded with a '2' in the fifth digit.
