Once you reach age 65, you become eligible for Medicare, the federal government’s health insurance program primarily geared toward seniors and retirees. 

Whether you retire early or plan to work for several more years, have already turned 65, or are still a few birthdays away, it’s worth thinking about which Medicare plan you’ll sign up for when the time comes.

Medicare Advantage, or Medicare Part C, is one Medicare plan option — but is it the best choice for you, or should you stick with Original Medicare? Here we'll cover nine major reasons Medicare Advantage could conflict with your retirement goals. 

By the time you finish reading, you’ll have a better understanding of whether Medicare Advantage could work for you or if you should explore other Medicare coverage options.

It has a much smaller healthcare provider network

Most — though not all — American healthcare providers accept Original Medicare insurance. The same can’t be said for Medicare Advantage, which has a much smaller provider network. 

If finding a provider you love is important to you, Original Medicare will give you more options. With Medicare Advantage, you’ll have to settle for the best care you can find within the network.

Since Medicare is administered by the federal government, you can use it at any hospital or medical provider in the United States (as long as that provider accepts Medicare, which most do). 

In contrast, Medicare Advantage’s smaller provider network is also extremely localized. Whenever you’re seeking non-emergency care, you’re limited to providers in your immediate area.

Its provider network is especially small for rural communities

No matter where in the country you live, Medicare Advantage’s network is smaller than Original Medicare’s network, but the network is especially limited for rural communities. 

According to one study published in 2021, 10.5% of rural retirees who sign up for Medicare Advantage end up switching to Original Medicare. 

By way of comparison, only 5% of non-rural retirees switch away from Medicare Advantage.

It usually requires referrals to see specialists

With Original Medicare, you can schedule a specialist visit even without a referral. With Medicare Advantage, though, you can’t simply call a specialist and schedule an appointment. 

Instead, you need a referral from a primary healthcare provider before you can speak with a specialist.

It requires preauthorization for most high-cost services

If you’re enrolled in Medicare Advantage, you’ll likely end up paying for some of the most expensive healthcare services out of pocket unless you get the expense pre-approved. 

Those services include inpatient hospital stays, partial hospitalizations, physical therapy, dialysis, hearing exams, psychiatric services, and much more.

If you don’t get the expense approved in advance, you’ll likely end up paying for it out of pocket. For the most part, Original Medicare doesn’t require preauthorization.

It often requires preauthorization for Part B medications

Medicare Part B is the medical insurance section of Medicare, and it’s included in all Medicare Advantage plans. 

However, you’ll need prior approval before your Medicare Advantage plan will help pay for any outpatient drugs prescribed under Part B (rather than Part D, which covers most other prescriptions).

Most Part B drugs that require preauthorization are injectable, including injectable medications for osteoporosis, injectable blood-clotting factors for hemophilia, and some oral and injectable end-stage renal disease medications.

It can require step therapy for Part B drugs

Step therapy refers to the practice of using a cheaper medication to treat a condition before moving to a more expensive medication. 

Unlike Original Medicare, Medicare Advantage plans can require step therapy for Part B medications, meaning your Medicare Advantage plan can refuse to cover medication prescribed by your doctor if there’s a cheaper alternative.

Note that step therapy doesn’t mean replacing a name-brand medication with a cheaper generic version of the same drug. Instead, it means that if two completely different medications treat the same issue, your Medicare Advantage provider can require you to try the cheaper medication first.

It might make hospital stays more expensive

Medicare Advantage might be cheaper for some retirees, especially those who mainly see healthcare providers for preventative health. 

But if you end up in the hospital for a week, studies show that 50% of seniors using Medicare Advantage will pay more for that stay than seniors using Original Medicare.

In other words, if you have poor health and know you’re at a higher risk of hospitalization, Medicare Advantage might cost you more over time than Original Medicare.

It can make budgeting for healthcare even harder

Since you can’t always anticipate your health needs in advance, budgeting for healthcare is notoriously tricky. If you’re living on a fixed income, though, you need to carefully track your expenses to make sure you don’t overspend.

Original Medicare makes healthcare expenses easier to anticipate by charging you a recurring monthly premium. As a result, you can then visit a healthcare provider at a lower cost and without rearranging your budget to accommodate the additional expense.

In contrast, most Medicare Advantage plans don’t have a monthly premium. Instead, you pay for medical expenses out of pocket until you hit your out-of-pocket max, which makes it hard to know how much you could be spending on healthcare in a given month.

Bottom line

Medicare Advantage plans can offer crucial benefits that make life easier for some retirees, especially those in good health with relatively few healthcare needs. But it’s definitely not the right choice for everyone. 

If you anticipate hospital stays, prefer to pick your own provider, and dislike the idea of getting prior approval for most expenses, Original Medicare might be a better choice for you to prevent the need to make extra money for insurance.
