So the correction is he strictly has Medicare advantage that is managed by aetna
Like I said Medicare advantage will always have red tape some are better then others, And there will be cost share
If you can get him to move in and get GI Medicare supplement plan F would cover everything and its 2ndary to medicare so The Insurance company cant decline are required preauth when medicare approves
However, if that is not possible. You can ask the provider which plans they prefer, If he has financial assistance from either state for drugs or Medicaid he can change right away
If not you will have to wait till AEP
