Hello,

Please look in to the following scenarios

1) If Physician Documented Type2 MI or Type 2 NSTEMI what will be the code?

2)Tyepe 2 MI or Type 2 NSTEMI Probably Demand ischemia.

Question:
If a provider documents type 2 myocardial infarction
(T2MI) due to demand ischemia, how should it be
coded?
Answer:
Assign code I21.4, Non-ST elevation (NSTEMI)
myocardial infarction, for a T2MI. Typically, a
type 2 myocardial infarction is marked by non-
ST elevation, and occurs secondary to cardiac
stress due to other causes (i.e., ischemia resulting
from a supply-and-demand mismatch), without
atherosclerotic plaque rupture, but with myocardial
necrosis. Therefore, code a type 2 myocardial
infarction as a NSTEMI, unless otherwise
documented as STEMI.
