James Hale · Answer

Top Reasons-

Too much paperwork and denials: Medicare Advantage plans often require “prior approval” for cancer treatments. This creates extra work, delays, and more denials than Original Medicare.

Lower and slower payments: These plans usually pay hospitals less than traditional Medicare for the same care. Cancer treatment is expensive, so some centers lose money. Insurers may also take longer to pay.

Limited networks: Medicare Advantage uses smaller networks, and many top cancer centers are excluded.

How This Affects You-

Original Medicare gives you access to almost any hospital or doctor that accepts Medicare, with much less paperwork. However, it has no yearly out-of-pocket limit.

What You Would Typically Pay-

Part A (hospital/surgery): Deductible per benefit period + daily coinsurance for long stays.

Part B (outpatient chemo, radiation, doctor visits):  After the deductible, 20% coinsurance with no maximum. 

Prescription drugs: Covered under Part D with its own deductible, copays, and out-of-pocket maximum.

Example: $100,000 in outpatient care could cost you $20,000 or more out-of-pocket. Immunotherapy and targeted drugs will cost even more. 

How Most People Protect Themselves-

A Medigap policy usually covers the 20% coinsurance and deductibles, often bringing costs close to zero. You can buy any Medigap plan guaranteed issue (no health questions or denials) during the first 6 months after enrolling in Part B.

Bottom line: Traditional Medicare gives you broad access to doctors and hospitals with little prior authorization hassle, which is great for cancer care. But without a Medigap plan, a serious diagnosis can create large and unpredictable bills because there is no maximum on your liability.

Not every facility will be in network with every Advantage plan. If you want to make sure the cancer facility of your choice would be in network, should you need it, you should check this before you choose a plan.

This depends on the hospitals you use are in the network but no Advantage plan will pay 100%. You will need preauthorization  before treatment  can be covered.

Daniel Fraser · Answer

Contracts are signed between providers and the insurance carriers that are allowed to sell Medicare Health Plans (Medicare Advantage) in your area.  When these contracting periods occur, it is the decision between the hospital and the insurance company on if they want to participate with each other.  Normally this is financial matter but other reasons may come into play.

This is another example as to why it is imperative to work with an agent/broker that can determine if your providers are in-network with the Advantage plan you choose.

Melissa Hatten · Answer

Let me keep this real and simple, because this one confuses a lot of people.

Some hospitals don’t take certain Medicare Advantage plans for cancer treatment because those plans work with networks. And cancer care is expensive and very specialized.

Here’s what’s really going on:

First, Medicare Advantage plans have contracts with specific hospitals and doctors. If a hospital or cancer center isn’t in that network, they can choose not to accept that plan. It’s not personal—it’s business.

Second, a lot of top cancer centers want more flexibility than Advantage plans allow. These plans often require referrals, prior authorizations, and have set payment rates. Some hospitals don’t want delays when it comes to serious treatments like chemo, radiation, or surgery—they want to move fast.

Third, reimbursement can be an issue. If a hospital feels like the plan isn’t paying enough for the level of care they provide, they may decide not to participate at all.

Now let me say this part clearly—this does NOT mean Medicare Advantage is bad. It just means you have to check your doctors and facilities before you enroll.

This is exactly why I sit down with my clients and ask:
“If something serious happens, where do you want to go for treatment?”

Because the truth is…
It’s not just about your monthly premium.
It’s about access when you actually need it.

That’s the difference between picking a plan… and picking the right plan.

Frances Mitchell · Answer

It is all based on the contract the hospital has with Medicare and the Medicare Advantage company (if they have one) and what their reimbursement will be.

Grace Royer · Answer

Some hospitals do not accept Medicare Advantage plans for cancer treatment because the reimbursement rates are too low to cover the cost of care, in addition to the complex prior authorization process that creates significant administrative burdens for hospitals and their staff. Medicare Advantage plans typically require prior authorization for imaging tests, radiation therapy, inpatient hospital stays, outpatient oncology services, and certain types of chemotherapy that can cause treatment delays, denials, and inferior cancer care, and was a major reason some hospitals recently stopped accepting these plans.
