Turning 65 means you become eligible for Medicare—and eligible for some costly mistakes if you don't understand the enrollment rules. Medicare has enrollment penalties, a complex structure, and timing requirements that can affect your premiums for the rest of your life. Here's a plain-language guide for Florida residents approaching 65.
When to Enroll in Medicare
Your Initial Enrollment Period (IEP) is a 7-month window: the 3 months before the month you turn 65, the month you turn 65, and the 3 months after. Enrolling in the first 3 months means coverage starts on the first of your birthday month. Enrolling in the 4th month (your birthday month) or later results in a delayed coverage start.
The penalty for late enrollment in Part B: If you don't enroll during your IEP and don't have qualifying employer coverage, you'll pay a 10% premium increase for every 12-month period you were eligible but didn't enroll—permanently. This can add up significantly over a long retirement.
The Four Parts of Medicare
| Part | What It Covers | 2026 Cost Note |
|---|---|---|
| Part A (Hospital) | Inpatient hospital, skilled nursing facility, hospice, home health | Free for most; requires 40 quarters of Medicare taxes |
| Part B (Medical) | Doctor visits, outpatient care, preventive services, durable medical equipment | Standard premium ~$185/month in 2026; income-adjusted for higher earners |
| Part C (Medicare Advantage) | Private plans covering Parts A + B (and usually D) with extra benefits | Premiums vary by plan; network-based |
| Part D (Prescription Drugs) | Prescription drug coverage (standalone plan for Original Medicare) | Premiums from $0–$100+/month depending on plan and drugs |
Two Paths: Original Medicare vs. Medicare Advantage
Original Medicare (Parts A + B) — Accepted nationwide by any Medicare provider. Covers about 80% of approved costs; you pay 20% with no out-of-pocket maximum. Add a Medigap (supplemental) policy to cap your out-of-pocket exposure. Medigap policies sold in Florida include Plans A, B, C, D, F, G, K, L, M, and N—Plan G is currently the most comprehensive for new enrollees.
Medicare Advantage (Part C) — Private plans that bundle Parts A, B, and usually D. Often have lower monthly premiums and may include dental, vision, and hearing benefits not covered by Original Medicare. Trade-off: network restrictions (HMO or PPO), prior authorization requirements, and coverage gaps when traveling outside the plan's service area.
If you spend significant time in two states, Original Medicare + Medigap is usually better than Medicare Advantage. Original Medicare is accepted nationwide; Medicare Advantage plans are geographically limited and may not cover routine care outside their service area.
Delaying Medicare Enrollment If You Have Employer Coverage
If you (or your spouse) are still working at 65 and covered by a qualifying employer plan, you can delay Medicare enrollment without penalty. The employer plan must be from a current employer with 20+ employees. When you eventually leave that coverage, you have an 8-month Special Enrollment Period to enroll in Medicare without penalty.
Important: Retiree coverage, COBRA, and individual market coverage do not count as qualifying employer coverage for Medicare delay purposes.
What Doesn't Change with Medicare
Medicare doesn't cover routine dental, vision, or hearing care under Parts A and B. You'll need separate supplemental coverage or a Medicare Advantage plan that includes these benefits. Long-term care is also not covered by Medicare (skilled nursing is covered short-term; custodial care is not).
Choosing between Medicare Advantage and Original Medicare + Medigap is one of the biggest financial decisions of retirement. A licensed Florida advisor can help you compare based on your specific health needs, prescription drugs, and preferred providers. Call or get a free consultation.
