Prior authorization issues and the quest for profits are major issues with many Medicare Advantage plans, as outlined in this article.

“Traditional Medicare rarely requires so-called prior authorization for services. But virtually all Medicare Advantage plans invoke it before agreeing to cover certain services, particularly those carrying high price tags, such as chemotherapy, hospital stays, nursing home care and home health.

“Most people come across this at some point if they stay in a Medicare Advantage plan,” said Jeannie Fuglesten Biniek, associate director of the program on Medicare policy at KFF, the nonprofit health policy research organization. After years of steep growth, more than half of Medicare beneficiaries are now enrolled in Advantage plans, which are administered by private insurance companies.”
