An Aetna Medicare PPO member called to tell me that a local hospital would have to obtain prior auth for his MRI. I’ve always thought that PPOs would require prior auth, but more “relaxed”. When I looked in the Aetna PPO EOC, I found that the MRI (and other services) have wording that says that “may require Prior Auth”. The CIP lacks such wording. I don’t exactly think that it would be the case. Anybody have any experience with these Medicare PPO situations?
