I do have a suspicion that there is something else going on here or I am hearing only part of the story. 50 bad doctors in a row? That is strange. I am 59 and really have never encountered a bad physician/PAC/ARNP. Some had personalities I didn't care for but all seemed basically competent and did their jobs. Your brother does seem to be getting the scripts from somewhere since you are paying $700/month to fill them; where are they coming from if he has left or been rejected from all practices? Most opiate prescriptions are not refillable.
If Medicaid is working in your area you are fortunate, but that will change as it was designed to.
What does that mean?
He either stopped by or called and was told by 50 docs, he said, that they said they were no longer accepting new patients after being asked about his coverage, which is Wellcare another name for Medicaid.
I have never had a problem either, getting a doc but I have Medicare now and before that private insurance.
