While not scientific, even an informal survey of physicians revealed some interesting information about their willingness to perform BasicMed exams.
The BasicMed exam follows a similar structure to an FAA physical with one big difference. In an FAA medical, the doctor needs to identify if body parts, organ systems and other general things such as blood pressure are: Normal or Abnormal. If the AME finds something abnormal, s/he must provide a narrative. By identifying an abnormality, the AME is making a diagnosis of sorts. In a BasicMed exam, the same body parts and organ systems only need to be examined, but not identified as normal or abnormal, thus no diagnosis is made.
