DAR53, I see red when I think about the PBM's and how they're structured. The origin had good intentions but now it's a license to steal starting from the patient, docs, and Medicare. If I were inclined to do some heavy lifting like I used to do and research who what where and when PBM's came into existence my head would explode then I would contact my journalist friends to blow them out of the water but life is too short. Follow the money.
FYI, I did read the WSJ article I'm sure billions have been stolen from medicare. That's why our health insurance companies continue to increase the cost back to the tax payer.
