Medicare Advantage vs. Original Medicare: Which Is Better for Senior Care?

Medicare Advantage plans offer extra benefits and often lower premiums — but they come with network restrictions and prior authorization requirements that can significantly affect post-acute care options. Here is what families need to know.

Medicare Advantage plans (Part C) now cover more than half of all Medicare beneficiaries nationally — and many are excellent. But there are meaningful differences in how MA plans cover skilled nursing facility care, home health, and other post-acute services compared to Original Medicare. Understanding those differences before a parent is hospitalized avoids surprises at the moment of discharge.

Factor
Medicare Advantage (Part C)
Original Medicare (Parts A & B)
SNF Coverage
Medicare Advantage (Part C): Most MA plans cover SNF care but require prior authorization, may limit approved SNFs to a network, and may have different day limits or cost structures
Original Medicare (Parts A & B): Covers up to 100 days per benefit period after qualifying 3-day inpatient stay; any Medicare-certified SNF accepted
3-Day Rule
Medicare Advantage (Part C): Many MA plans waive the 3-day inpatient requirement — check your plan’s Evidence of Coverage
Original Medicare (Parts A & B): 3 consecutive inpatient days required before Medicare covers SNF care
Prior Authorization
Medicare Advantage (Part C): Typically required for SNF admission, home health, and sometimes hospital admission; plan has the right to deny or limit stays
Original Medicare (Parts A & B): No prior authorization required for covered services; no network restrictions
SNF Network
Medicare Advantage (Part C): Plan may limit covered SNFs to a preferred network; using out-of-network SNF may result in higher costs or no coverage
Original Medicare (Parts A & B): Any Medicare-certified SNF in the US accepts Original Medicare — no network restrictions
Extra Benefits
Medicare Advantage (Part C): May include dental, vision, hearing, fitness benefits, meal delivery, and transportation — benefits vary by plan
Original Medicare (Parts A & B): No extra benefits beyond standard Medicare coverage; supplement (Medigap) required for most beneficiaries
Out-of-Pocket Maximum
Medicare Advantage (Part C): Most MA plans have an out-of-pocket maximum (~$8,300/year in 2024) — Original Medicare has no cap
Original Medicare (Parts A & B): No out-of-pocket maximum; costs can be significant without Medigap supplemental insurance
Premiums
Medicare Advantage (Part C): Many MA plans have $0 monthly premium in addition to Part B premium; some plans rebate part of the Part B premium
Original Medicare (Parts A & B): Part B premium (~$174.70/month in 2024); most beneficiaries also pay Medigap premiums ($150–$400/month)
Appeals Process
Medicare Advantage (Part C): MA plans must follow a formal appeals process; BFCC-QIO can review denials for Medicare-covered services
Original Medicare (Parts A & B): Simpler appeals process; BFCC-QIO handles discharge and service denial reviews

The Bottom Line

Medicare Advantage plans work well for many beneficiaries — particularly those who are generally healthy, use their plan’s network providers, and value the extra benefits. The disadvantages become apparent when a parent needs post-acute care: network restrictions may eliminate preferred SNFs, prior authorization can delay needed care, and plan denials require appeals that add stress at an already difficult time. Original Medicare with a Medigap supplement provides more predictable, unrestricted coverage for serious illness and post-acute care — at higher total premium cost.
