What Prior Authorization Actually Means
Prior authorization means your insurance company has to approve a treatment, procedure, or referral before you receive it — even when your doctor recommends it. With Medicare Advantage, prior authorization is required for a wide range of services: specialist visits, imaging (MRI, CT scans), surgeries, certain medications, and inpatient hospital stays.
With Original Medicare and a Medigap supplement, prior authorization is not required. Medicare approves the service. Your Medigap plan pays their portion. You're done.
What Happens When Prior Authorization Is Denied
In 2024, a federal report found that Medicare Advantage plans denied millions of prior authorization requests — including many that were later overturned on appeal. The appeal process can take weeks. During that time, you're either not receiving treatment, paying out-of-pocket, or dealing with a healthcare bureaucracy while managing a medical situation.
For Florida seniors with serious conditions — cancer, heart disease, orthopedic needs — the prior authorization process can delay care that should have started immediately. Some seniors describe it as “fighting with a call center while trying to get healthy.”
The Network Problem Compounds Everything
Prior authorization is only half the problem. Medicare Advantage plans also restrict you to in-network providers. If the specialist your primary care doctor recommends isn't in-network — and in Florida, this happens constantly as doctor participation in MA networks changes year to year — you either pay full out-of-network rates or find a different specialist and start over.
With Medigap, your doctor refers you to whichever specialist they believe is best for your condition. No network check. No out-of-network bill.
Why Florida Seniors Switch After a Diagnosis
The pattern is common: a Florida senior chooses Medicare Advantage at 65 because the $0 premium is attractive. For several healthy years, it works fine — they rarely use healthcare and the plan functions adequately.
Then comes a significant diagnosis. Suddenly prior authorization delays are affecting their treatment timeline. The out-of-pocket costs they didn't focus on — copays, coinsurance, the $9,350 in-network maximum — become real numbers they're tracking every month. Their preferred specialists aren't in-network. The plan they thought was “free Medicare” turns out to have been insurance company insurance all along.
At that point, switching to Medigap requires medical underwriting. With a recent serious diagnosis, carriers can deny them. They're stuck.
The Decision You Make at 65 Has Long-Term Consequences
Medicare Advantage can make sense for healthy seniors who are primarily motivated by minimizing monthly costs and who understand the trade-offs. But the decision made at 65 is harder to reverse at 73 with a health history.
Medigap's open enrollment window — the 6-month period starting when you turn 65 and enroll in Part B — is the one time in your life when any carrier must accept you, with no health questions, at standard rates. After that window closes, carriers can and do use medical underwriting.
The seniors who regret Medicare Advantage are almost never the healthy ones who rarely use it. They're the ones who got sick and discovered the hard way what prior authorization, network restrictions, and out-of-pocket maximums actually mean.
