@nigho My hospital has a standard pump which wasn’t what I was looking for (I think it was Roche). When I approached them for a pump, I told them it had to be Medtronic because it was the only one with integrated CGM at the time and that was a requirement for me which I could demonstrate from a trial would deliver health benefits. I talked to them about the need for patient choice and for healthcare to be tailored to the needs of the patient.
I would struggle to make a case to argue that an Omnipod was medically necessary over a tubed pump. I think your only argument would be patient choice.
