Medicare Advantage · Part C
Medicare Advantage Plans
Medicare Advantage is a private-plan alternative to Original Medicare that bundles your hospital (Part A), medical (Part B), and usually prescription (Part D) coverage into a single plan — often adding dental, vision, and hearing benefits Original Medicare doesn’t cover. More than 34 million people are enrolled. Here’s how it works, what it costs in 2027, and whether it fits.
Do you qualify?
Advantage eligibility is straightforward — it comes down to three things.
Enrolled in Part A & B
You must already have Original Medicare (both Part A and Part B) before you can join an Advantage plan.
Live in the service area
Advantage plans are regional. You must live in the plan’s service area — availability and pricing vary by county.
In an enrollment window
You can join when newly eligible, during fall Annual Enrollment, or via a Special Enrollment Period.
What it costs in 2027
You keep paying your Part B premium either way. Beyond that, Advantage costs are plan-specific — but a few numbers are set nationally.
~$202/mo
Part B premium (2027)
You keep paying this to Medicare whether or not you choose Advantage.
$0 - low
Plan premium
Many Advantage plans have a $0 monthly premium; costs come through copays instead.
~$2,400
Part D drug cap (2027)
If the plan includes drug coverage, your covered-drug spending is capped at ~$2,400 for the year.
Annual max
Out-of-pocket limit
Every plan caps your yearly in-network costs — a safety net Original Medicare doesn’t have. Medicare sets the ceiling each year (roughly $9,250 for in-network in 2027); many plans set theirs lower.
Advantage vs. Original Medicare
The real trade-off is flexibility versus bundling. Neither is "better" — it depends on how you use care.
| Category | Medicare Advantage | Original Medicare |
|---|---|---|
| Doctors | In-network (HMO/PPO); referrals often needed on HMOs | Any provider nationwide who accepts Medicare |
| Drug coverage | Usually built in | Requires a separate Part D plan |
| Extra benefits | Often dental, vision, hearing, fitness | Not included |
| Out-of-pocket cap | Yes — annual maximum | No cap (many add Medigap for protection) |
| Prior authorization | Common for some services | Rare |
