Question 1

Is Medigap or Medicare Advantage better in New Jersey?

Accepted Answer

It depends on your priorities. Medigap (Medicare Supplement) is better if you want the freedom to see any doctor in the US who accepts Medicare, predictable costs, and no network restrictions. Medicare Advantage is better if you want a lower monthly premium, don't mind a network, and want extra benefits like dental and vision bundled in. In New Jersey specifically, Medigap's community rating and guaranteed issue rules make it unusually accessible compared to other states.

Question 2

Can I switch from Medicare Advantage back to Medigap in New Jersey?

Accepted Answer

Yes — and New Jersey makes this easier than almost any other state. Under NJ's year-round guaranteed issue rules, you can switch back to a Medigap plan at any time without being subject to medical underwriting. This is a critical difference from most states, where switching back to Medigap after Medicare Advantage can be difficult or impossible if you have health conditions.

Question 3

Do Medicare Advantage plans cover all NJ hospitals?

Accepted Answer

Not all Medicare Advantage plans cover all New Jersey hospitals. Network coverage varies significantly by plan and county. Major NJ health systems like RWJBarnabas, Hackensack Meridian, Atlantic Health, and Capital Health may or may not be in-network depending on which plan you choose. Always verify your specific doctors and hospitals are in-network before enrolling in a Medicare Advantage plan.

Question 4

Are Medicare Advantage plans really $0 premium in New Jersey?

Accepted Answer

Many Medicare Advantage plans in New Jersey do have $0 monthly premiums, but you still pay your Part B premium ($185/month in 2026). The $0 refers to the plan's additional premium on top of Part B. These plans generate revenue through Medicare's capitated payments and your cost-sharing (copays, deductibles) when you use services.

Question 5

Which is more expensive long-term — Medigap or Medicare Advantage in NJ?

Accepted Answer

This depends entirely on your healthcare usage. Medigap Plan G costs more per month upfront ($130–$220/month) but provides near-zero additional costs when you use healthcare. Medicare Advantage may cost less per month but has copays, deductibles, and out-of-pocket maximums (up to $8,850 in-network in 2026) that can add up quickly if you have a serious illness or hospitalization.
