An ED-to-inpatient admission begins with chest pain. After study, NSTEMI is confirmed and treated during the stay. Which principal diagnosis selection best follows inpatient guidelines?
Select an answer to reveal the explanation.
Short Explanation
Chest pain got them through the door; NSTEMI is what the workup proved. For the inpatient stay, the confirmed acute MI after study is the principal—not a frozen chief-complaint time capsule.
Full Explanation
Inpatient principal diagnosis reflects the condition established after study that chiefly occasioned admission. When evaluation confirms NSTEMI and that acute condition accounts for the admission, NSTEMI—not undifferentiated chest pain—is the appropriate principal selection. Confirmed acute conditions replace unresolved symptom coding for principal diagnosis when guidelines so direct.
