Turning 65 is one of the most significant Medicare milestones. In Florida — with more Medicare beneficiaries than almost any other state — the decisions you make at 65 set the foundation for your healthcare coverage for decades. Here is your complete enrollment guide for 2026.

Medicare Parts A and B: The Foundation

Medicare Part A covers hospital inpatient care, skilled nursing facility care, hospice, and some home health care. Most people receive Part A premium-free if they or their spouse worked at least 40 quarters (10 years) paying Medicare taxes.

Medicare Part B covers outpatient medical services — doctor visits, preventive care, lab tests, durable medical equipment, and more. Part B has a monthly premium ($185 in 2026 for most beneficiaries) and an annual deductible ($257 in 2026).

When to Enroll

Your Initial Enrollment Period (IEP) spans 7 months: the 3 months before your 65th birthday month, your birthday month, and the 3 months after. Enrolling in the 3 months before your birthday ensures coverage starts on your birthday month. Enrolling after your birthday month delays your start date.

If you have employer-sponsored health insurance through active employment (yours or a spouse's), you can delay Part B without penalty. Once that coverage ends, you have an 8-month Special Enrollment Period to enroll in Part B.

Choosing Between Medicare Advantage and Medigap at 65

At 65, you have your most powerful Medigap opportunity: the 6-month Initial Enrollment Period during which insurers cannot deny you or charge more based on health history. This is your lifetime Guaranteed Issue right. Many seniors who choose Medicare Advantage at 65 later wish they had chosen Medigap — and find they cannot qualify medically when they try to switch.

If you are in good health at 65 and want lower premiums, Medicare Advantage may be appropriate. If you have any chronic conditions, travel frequently, or want maximum provider freedom, Medigap at 65 is almost always the better long-term choice.

Part D Prescription Drug Coverage

If you choose Original Medicare plus Medigap, you need a separate Part D prescription drug plan. Enroll during your IEP to avoid the late enrollment penalty (1% of the national base premium per month you were without coverage). Compare Part D plans at Medicare.gov using your specific medication list.

Florida-Specific Considerations

Florida's issue-age Medigap pricing makes enrolling at 65 particularly advantageous. Your premium is locked at your enrollment age — the younger you enroll, the lower your lifetime premium base. Florida also has a large Medicare Advantage market with competitive plans, but the 2026 carrier exits are a cautionary tale about MA plan stability.
