Best Medicare Advantage drug plan for Prostate Cancer?

MA plans contract with a provider network and that is one of the ways that they keep their premiums low and can provide additional (minor) benefits. .
If you are not in network, you need an exception to be treated out of network.
MA plans try to "squeeze" providers on reimbursement, and some top line facilities will not accept the reduced payments.
Traditional Medicare together with a comprehensive Med Supp (G) provides the most coverage and choice available, if you can afford the Med Supp premium.
Nothing wrong with MAs per se, just understand that they are private insurance companies marketing a profitable product, with network restrictions.

For instance, a company starting with the first letter of the alphabet refused to cover my mpMRI. When I appealed I never heard a thing back...ever! Fortunately, I could afford to pay for that MRI, even though it turned out the in-network provider had less than up-to-date equipment and I had to redo it. Further, the redo, to guide the transperineal biopsy, found a more advanced node of cancer that the first MRI missed in either the view or the analysis.
And, fortunately for me, I was within the initial window after age 65 that allowed me to switch back to traditional medicare with a high-deductible plan G supplement, and not to deal with the medicare advantage squeeze for people who actually need expensive care.

When switching or picking a Medicare supplement it is best to review costs, benefits, including part d drug plans with a qualified agent that can help pick the plan best for you. They are independent and cost you nothing.
The details of your costs and most importantly the availability of providers are best reviewed with the agent who will give you the best analysis of plan’s available. And MA is likely not your best choice and plan G may be your best supplement.
Good luck but rely on an expert not associated with any insurance company.

Some time ago this came up and a lot of discussion about Medicare and difference with Medicare Advantage. I had mentioned a yearly letter put out by Mayo Jacksonville on this subject each year. I recently got this for 2023 and have pasted it for review. It covers Jacksonville Mayo not Phoenix or Rochester but explains that Medicare Advantage is NOT traditional Medicare that Mayo Clinic will take.
