Short answer: Your enrollment window is 7 months around your 65th birthday — enroll in the first 3 months so coverage starts on time and you avoid lifelong penalties. Below: the Delaware-specific piece most guides skip.
Turning 65 in Delaware means the same federal deadline as everywhere — plus state specifics worth knowing before you choose. Here's the plain-English version.
Your 7-month Initial Enrollment Period
The window: 3 months before your birthday month, the month itself, and 3 months after. Enroll early for coverage that starts the first of your birthday month. Miss it without other creditable coverage and the Part B penalty (10% per full year delayed, for life) and the Part D drug-coverage penalty apply.
Delaware: small state, sharper choices
Delaware's Medicare market is compact — fewer plans than its big neighbors, anchored by a small set of health systems (ChristianaCare, Bayhealth, Beebe). That cuts both ways: comparison is quicker, but each network decision carries more weight because the alternatives are fewer. Many Delawareans also see Philadelphia-area doctors — if that's you, make sure your plan crosses the state line with you.
