How would you code a patient who was discharged from the hospital with a diagnosis of probable myocardial infarction without a history of MI in the past?
The ICD-9 (Ingenix version pages 27/28) guidelines specifically state that for inpatient encounters only do you code possible's, likelies etc. So you would code the MI and the Hx of MI ICD-9 codes.
The exact question is: If a patient were discharged from the hospital with a diagnosis of probable myocardial infarction without a history of MI in the past, what ICD-9 code would the coder document for this stay?
The diagnosis is probable myocardial infarction but there is no history of it, so I say none.
