If you (or a spouse) are approaching 65 in Orlando, Kissimmee, Orange County, or Osceola County, Medicare has its own calendar. It is not the same as Medicare Annual Enrollment (AEP), and it is not the same as ACA marketplace open enrollment.
This post is a plain timeline for people new to Medicare. Instant Health Help is a licensed Central Florida health insurance agency. We are not an insurance carrier. We do not invent plan names, prices, or “best plan” claims—availability and costs depend on your zip code, doctors, and medications.
Initial Enrollment Period (IEP), in plain English
Your Initial Enrollment Period is a seven-month window around your 65th birthday:
- Three months before the month you turn 65
- The month you turn 65
- Three months after the month you turn 65
During IEP you can typically enroll in Part A and Part B, and then look at how you want to fill gaps—Medicare Advantage, a Medicare Supplement (Medigap) with a separate Part D plan, or other combinations that fit your situation.
Timing of when coverage starts can depend on which month inside that window you enroll. If you are still working and have employer coverage, rules can differ—bring that paperwork when you talk with an agent or check Medicare.gov.
IEP is not AEP (and not ACA open enrollment)
Central Florida residents often mix up three calendars:
| Window | Who it is for | Typical timing |
|---|---|---|
| Initial Enrollment Period | People first becoming eligible (often turning 65) | 7 months around your birthday month |
| Medicare Annual Enrollment (AEP) | People who already have Medicare and want to change Advantage or Part D | Oct 15–Dec 7 (changes usually Jan 1) |
| ACA / marketplace open enrollment | People shopping marketplace (Obamacare) plans | Typically Nov 1–Jan 15 |
If you are newly eligible, start with IEP—not AEP. AEP is for reviewing or changing coverage you already have. Marketplace open enrollment is a different program with different rules and subsidies.
What to gather before you compare options
You do not need a binder full of marketing. Bring (or have ready):
- Zip code and county — Orange and Osceola plan menus are not identical to other Florida counties.
- Doctor and hospital list — Primary care, specialists, and preferred facilities.
- Medication list — Names, doses, and how often you fill them.
- Current coverage — Employer plan, COBRA, marketplace plan, or a spouse’s plan, plus any retirement date.
- Travel habits — Snowbird time, out-of-state family, or mostly local care.
Those five items are enough for a licensed local agent to walk through what is actually available where you live—without guessing.
Part A, Part B, and the “what next?” decision
Most people start by understanding:
- Part A — Hospital insurance (many people have premium-free Part A based on work history).
- Part B — Medical insurance (doctor visits, outpatient care; usually has a monthly premium set by Medicare).
- What covers the rest — Original Medicare alone leaves deductibles and coinsurance. Many people then compare Medicare Advantage (Part C) or a Medicare Supplement plus Part D for prescriptions.
Neither Advantage nor Supplement is automatically “better.” Networks, travel, drug lists, and how you prefer to pay (premium vs copays) drive the fit. We will not tell you there is one best plan for everyone in Central Florida—because there is not.
Special situations to flag early
Call sooner rather than later if any of these apply:
- You (or your spouse) are still working past 65 with group coverage
- You have disability-based Medicare and are approaching 65
- You lost other coverage and may need a Special Enrollment Period
- You are dual-eligible or get help with premiums or Extra Help for drugs
- You are moving into Orange or Osceola County from another state or county
Qualifying events and employer-coverage rules are case-specific. Official details live on Medicare.gov; a local agent helps you apply those rules to your doctors and county.
A simple September checklist for fall birthdays
If your 65th birthday falls in late 2026 or early 2027, use the next few weeks to:
- Confirm your IEP start and end months
- List doctors and meds
- Note whether you will keep working
- Decide whether you want a sit-down comparison before your birthday month gets busy
- Separate “new to Medicare” from “already on Medicare, reviewing at AEP”
Fall is also when AEP marketing ramps up. If you are newly eligible, prioritize your IEP timeline first so you do not miss your first window while sorting AEP ads meant for current members.
