Every September the mailers arrive, and almost all of them lead with the same number: $0 a month.
It is a real number. It is also the least useful one on the plan, because it describes when you pay, not how much. A $0-premium Medicare Advantage plan moves the cost from a monthly bill to the moments you use care — and for many people that is a perfectly good trade. You just need to know what you are trading.
What $0 does not include
Three costs sit outside the advertised premium on every Medicare Advantage plan.
- The Part B premium. You stay enrolled in Part B and keep paying it. The plan premium being zero does not change that
- Copays and coinsurance. You pay a share each time you see a specialist, have imaging, go to urgent care, or are admitted to hospital
- Prescription costs. Most plans include Part D drug coverage, which carries its own deductible and tier pricing
None of this is hidden — it is all in the plan’s Summary of Benefits. It is just not on the envelope.
The numbers that actually decide the cost
When we compare Medicare Advantage plans, these are the lines we read first, in this order.
1. The maximum out-of-pocket limit
Every Medicare Advantage plan has to cap what you pay for covered in-network medical care in a year. CMS sets a ceiling, and plans choose where to sit beneath it. Two $0 plans in the same county can have limits thousands of dollars apart.
This is the number that tells you how bad a bad year can be. If you had a hip replacement, a cancer diagnosis or a long admission next year, this is roughly what you would pay for the medical side. Read it first.
2. The per-day hospital copay
Most plans charge a fixed copay for each day of an inpatient stay, for the first several days of each admission. A plan with a low premium and a high daily copay can cost far more in a single admission than a plan with a modest premium. The same applies to skilled nursing stays, which often carry daily copays after the first few days.
3. Specialist, imaging and outpatient copays
If you see a cardiologist quarterly, have regular scans, or are likely to need outpatient surgery, these lines matter more than the premium. Look at the specific services you actually use, not the general office-visit copay.
4. Your drugs on this plan’s formulary
The drug side can outweigh everything above. The same prescription can sit on a different tier — or not be covered at all — from one plan to the next. We price every plan against your actual medication list, because that is the only way to see the total. The reasoning is in bring your pill bottles.
Price a realistic year and a bad year
Add the premium to what you would spend in a normal year with your current doctors and prescriptions. Then add the premium to the out-of-pocket maximum. The first number is what the plan probably costs you. The second is what it could cost you. A plan is only cheap if both are acceptable.
The network is part of the price
A Medicare Advantage plan pays for care from providers it covers. On an HMO, that generally means in-network only, outside emergencies, and often a referral to see a specialist. On a PPO, you can go out of network, usually at a higher cost share.
Before any number matters, check three things:
- Your doctors are in the network for the coming year, not just this one. Networks change on January 1
- The hospital you would actually want is covered — name it before you name a plan
- Prior authorization rules for the treatments you are likely to need. Many services require the plan’s approval in advance, and that is a real difference in how a plan feels to use
If you spend part of the year in another state, the network question gets more serious. Most HMOs cover routine care only in their service area.
What the extras are worth
Dental, vision, hearing, fitness memberships and over-the-counter allowances are real benefits, and for some people they tip the decision. Read them closely. Dental benefits often have annual limits that cover cleanings and a filling rather than a crown. Allowances can come with restrictions on where they can be spent.
Value the extras at what you would genuinely use. Then compare that against the difference in out-of-pocket exposure between plans. The extras rarely outweigh a plan that does not cover your cardiologist. What Original Medicare does and does not pay for here is set out in dental, vision, hearing: what Medicare leaves out.
When a $0 plan is the right answer
Often. A $0-premium Medicare Advantage plan is a sound choice when:
- Your doctors and preferred hospital are in its network for next year
- Your drugs are covered at a tier you can live with
- You could absorb the out-of-pocket maximum in a bad year
- You stay mostly in one area
It is a weaker choice if you travel widely, see several specialists outside the plan’s network, or would struggle financially with a high out-of-pocket year. For some of those people a Medigap plan with a standalone Part D plan is the better structure. For others, a hospital indemnity policy alongside the Advantage plan closes the gap that worries them. Both are worth pricing before you assume.
Before October 15
The Annual Enrollment Period runs from October 15 to December 7. Plans publish their details for the coming year shortly before it opens, and your current plan’s Annual Notice of Change should already have arrived.
A plan comparison is free. We price every plan we offer in your county against your doctors and prescriptions, show you the realistic-year and bad-year totals side by side, and tell you plainly if the $0 plan is the right one. If you would rather start now, book a call — it takes about thirty minutes.
Frequently asked questions
Do I still pay the Part B premium on a $0 Medicare Advantage plan?
Yes. A $0 plan premium means the plan itself charges nothing on top. You remain enrolled in Medicare Part B and keep paying the Part B premium, usually deducted from your Social Security benefit. A small number of plans reduce part of that Part B premium, which is a separate feature and not the same as a $0 plan premium.
How can a Medicare Advantage plan charge no premium at all?
Medicare pays each plan a monthly amount for every member it enrolls. Plans use that payment, together with the copays and coinsurance members pay as they use care, to fund the benefits. A $0 premium tells you how the cost is collected — at the point of care rather than every month — not that the cost has gone away.
What is the most important number on a Medicare Advantage plan?
The in-network maximum out-of-pocket limit. It is the most you can be asked to pay in a year for covered medical services, and it is the number that decides how bad a bad year can get. Read it alongside the network, because the limit only protects you for care from providers the plan covers.
