How they differ

Medicare Advantage (Part C) replaces Original Medicare with a private plan. Many have low or $0 premiums, include drug coverage, and add extras like dental or vision, but you use the plan's network rules and pay copays or coinsurance up to a yearly out-of-pocket maximum.

Medigap pairs with Original Medicare and helps pay the costs Medicare leaves behind. It costs a monthly premium on top of Part B and a separate drug plan, but it is accepted nationwide by any provider that accepts Medicare.

Side by Side

	Medicare Advantage	Original Medicare + Medigap
Monthly premium	Often low or $0, plus your Part B premium	Medigap premium, plus Part B and a drug plan
Choice of doctors	Plan network rules apply	Any provider that accepts Medicare
Drug coverage	Often included	Separate Part D plan
Extras	Often dental, vision, hearing	Not included in Medigap
Cost when you use care	Copays up to a yearly out-of-pocket maximum	Medigap covers much of what Medicare leaves behind, depending on the plan letter

What matters for an active retiree

Frequent travellers often value Medigap's nationwide flexibility. Others prefer a Medicare Advantage plan's lower premium and added benefits. Neither is better for everyone, and the right answer depends on your doctors, your drugs and how much you are away.

Timing matters: your Medigap open enrollment window is six months from the month your Part B starts. After that, insurers in most cases can use medical underwriting. Moving between plans later can be harder, so decide with care.

The trend

Medicare Advantage has grown from 19% of eligible beneficiaries in 2007 to 55% in 2026, according to KFF. That growth is why it is worth comparing carefully, since networks, benefits and costs differ widely from plan to plan.
