Question 5: A patient presents with acute chest pain and hypertension. History reveals that he inhaled four lines of cocaine within the past hour and has been abusing cocaine for the past year. The physician performs and documents a comprehensive history and exam.

Diagnostics include a cardiac panel and drug screen, and an electrocardiogram (EKG) reveals ST elevation in the anterior leads. Lab work shows elevated CPK and troponin. The physician treats the patient with intravenous Valium and starts him on a nitroglycerin drip. The physician then admits the patient to the critical care unit with anterior wall ST segment elevation myocardial infarction (STEMI) due to cocaine poisoning and hypertension. The physician reports 45 minutes of critical care time.

Which diagnosis codes should you link to 99291 (Critical care, evaluation and management of the critically ill or critically injured patient; first 30-74 minutes) for this visit?
