It is not just double dipping. I've been on a common statin for 18 years and my doctor still insists I come into his office every couple of months to renew my prescription even though my pharmacists phones to get a renewal. No tests, no consultations, just a scribbled prescription and a billing to Medicare. Also, I keep requesting a generic form of the drug but he also specifies the much more expensive brand named version  every time. Did I mention that he takes 2-3 cruises a year?
