The short answer: If you are already on Medicare, the work is no longer about signing up — it is about re-checking. Your plan can change every January, your prescriptions change, and the coverage that fit you two years ago may quietly not fit anymore. Medicare gives you a window every fall to act on that, plus a second one in the new year for some people. This page is what to check, and when.
Most Medicare advice is aimed at people turning 65. Once you are enrolled, the conversation mostly stops — which is unfortunate, because the enrolled years are where the routine money is won and lost. Not through anything dramatic. Through a formulary change nobody read, a pharmacy quietly leaving a network, or a policy that made sense at 66 and is being carried out of habit at 74.
What actually changes every year
Four things move, and they move independently of each other:
- Your drug plan’s formulary. Which medications are covered, and on which tier, is re-set each year. A prescription that was inexpensive can move tiers without your prescription changing at all.
- Networks. Doctors, hospitals and pharmacies join and leave. A “preferred” pharmacy can stop being preferred while remaining in the network — a distinction that costs real money and is invisible until you are at the counter.
- What the plan charges. Premiums and cost-sharing are re-set annually across the market.
- You. New diagnosis, new medication, a specialist you did not see last year, a move, a spouse’s coverage ending. Your own situation changes more often than the plans do.
Every plan has to tell you what it is changing. The notice arrives by the end of September, before the fall window opens, and it is the single most ignored piece of mail in American retirement. It is worth twenty minutes.
Your two annual windows
Fall: October 15 to December 7
This is the one everybody’s television knows about. During it you can join, drop or switch a Medicare Advantage plan, and join, drop or switch a drug plan — including moving between Original Medicare and Medicare Advantage in either direction. Whatever you choose takes effect January 1, and the request has to be in by December 7. There is a printable checklist for that window — what to compare, and in which order.
Doing nothing is also a decision. Your coverage renews as-is, with next year’s terms rather than this year’s.
New year: January 1 to March 31
A second window, and a narrower one: it is only for people already in a Medicare Advantage plan. If that is you, you can move to a different Advantage plan, or leave for Original Medicare and pick up a drug plan on the way out. If you are on Original Medicare, this window is not yours — which surprises people every February.
It exists as a correction period. If January’s first pharmacy visit or first specialist referral reveals that a plan does not fit, you are not stuck with it until next December.
The window that does not reopen — your supplement
Here is where the annual rhythm stops applying, and where Georgians in particular should slow down.
Drug plans and Advantage plans reset every year. Medicare Supplement policies do not. There is no annual window in which you may change supplement companies without answering health questions, and Georgia has not adopted the birthday-rule style annual do-over that some states offer. Outside your original six-month window and certain federal guaranteed-issue situations, changing supplements generally means medical underwriting — questions, and a company allowed to decline.
That does not mean never look. It means look in the right order: find out whether you would qualify before you fall in love with a lower premium, and never cancel what you have until the new policy is approved in writing. The Georgia-specific rules are laid out on turning 65 in Georgia, and they keep applying long after 65.
What to check each fall
- Your current medication list, with doses — not last year’s list. This is the single input that matters most.
- Your pharmacy, and whether it is still preferred under next year’s terms.
- Your doctors and any specialist you have started seeing, checked against next year’s network rather than this year’s.
- The change notice that arrived in September — specifically the part describing what is different, not the welcome language at the front.
- Anything that changed in your life: a move, a diagnosis, a spouse’s retirement, a new prescription you expect to stay on.
If all five come back unchanged, the honest answer is often “stay where you are,” and that is a perfectly good outcome of a review. A review that always ends in a switch is not a review.
Two numbers are worth re-checking while you are at it: your income against the IRMAA brackets, which reset every January, and any late enrollment penalty sitting on your premium.
When something changes mid-year
You are not locked in until October if your circumstances genuinely change. Special Enrollment Periods exist for events like moving out of your plan’s service area, losing other coverage, entering or leaving a facility, or qualifying for help with costs. Each has its own clock, and the clocks are short — which is the argument for asking when the event happens rather than at the end of the year.
Where to go deeper
- Drug coverage — how Part D actually works: formularies, tiers, pharmacy networks, and the annual cap.
- The structural question — supplement or Medicare Advantage, and why the door between them swings easily in only one direction.
- If you hold a supplement — why your premium went up when your coverage did not, and how Plan G and Plan N differ if you are comparing letters.
- What things cost — the honest breakdown, in words rather than a brochure.
- Coverage questions as they come up — the Learning Center answers the “does Medicare cover…” list, from dental to home health care.
- Planning past medical coverage — long-term care is the gap Medicare was never built to fill, and health is the deadline for arranging it.
- Local help — North Georgia senior resources: senior centers, the state’s no-cost counseling line, and Social Security contacts.
Common questions once you are on Medicare
Do I have to do anything during Open Enrollment?
No — coverage renews on its own. But it renews under next year’s terms, not the ones you signed up for, so “doing nothing” only stays a good decision if you have checked what changed. The review is the obligation; the switch is optional.
Can I change my Medicare Supplement during Open Enrollment?
This is the most common misunderstanding of the fall window. Open Enrollment governs Advantage plans and drug plans. Supplements are on their own track, with no annual window — and in Georgia, no birthday rule. You can apply at any time of year, but outside protected windows you can also be declined.
I am happy with my plan. Is a review still worth it?
Usually yes, and often it confirms you should stay. Satisfaction is measured against the year you have had; the review is against the year ahead, with a formulary and a network you have not seen yet. Twenty minutes to confirm nothing needs doing is twenty minutes well spent.
Why does my drug cost change when my prescription did not?
Because the plan’s tiers were re-set, or your pharmacy’s standing in the network changed, or both. The medication is identical; the coverage around it moved. It is the most common reason a January pharmacy visit feels wrong, and it is fixable — inside the right window.
Does a review cost me anything?
No. The insurance company pays the agent, and what you pay is the same whether you use one or handle it yourself. What a review should produce is a clear recommendation — including “stay put” when that is the right answer.
The simple version
Once you are enrolled, Medicare becomes an annual habit rather than a decision. Read the September notice, check your medications and pharmacy against next year’s terms between October 15 and December 7, use the January-to-March window if you are on an Advantage plan and something is not fitting — and treat your supplement as the one piece that does not reset, especially in Georgia. Keep that rhythm and the surprises mostly stop happening.
Want a second set of eyes this fall?
That is the annual review, and it is the part of this work that never shows up in a brochure: the same person, every year, checking whether what you have still fits — and saying so when it does.
