Medicare Advantage by state
Delaware is a small, single-metro market, so the plan list is short but genuinely competitive across New Castle County. South of the canal the choices thin out, and Sussex County’s large retiree population has fewer plans than its size would suggest.

What matters
Highmark Blue Cross Blue Shield Delaware, Aetna, UnitedHealthcare and Wellcare are the names most residents see, with a handful of special needs plans for dual eligibles. New Castle County carries most of the competition; Kent and Sussex often have two or three plans.
Premiums at or near $0 are common, and most plans include drug coverage with modest copays. Because the state is compact, nearly every plan network covers the same Wilmington hospitals, so cost differences come down to copays and formularies.
Delaware allows medical underwriting on Medigap after the six-month open enrollment period, so a supplement bought at 65 is the only guaranteed one. Advantage plans are priced by county here, which matters for anyone considering a move to the beach counties.
The Delaware Medicare Assistance Bureau, known as DMAB, counsels residents for free, and the Delaware Department of Insurance handles complaints about plans and agents.
