Four things to write down before the fall enrollment windows open

The fall calendar is fixed: Medicare's Annual Enrollment Period runs October 15 through December 7, and Marketplace Open Enrollment begins November 1 in most states. Nothing on it is due in August. What August is good for is the unglamorous part — gathering the four things every one of those conversations asks for.

1. Your medications, exactly as written

Names, strengths, and how often you take each one, including anything taken occasionally. Drug lists change from year to year, so the useful question isn't "is my drug covered" in general but "how does next year's formulary treat this specific drug at this dose." A phone photo of each label is faster than transcribing, and it removes the guesswork that makes people rely on memory in the middle of a comparison.

2. Your providers and facilities

Primary care, every specialist you actually see, your preferred hospital, and the pharmacy you use. Networks are per-plan and change at year boundaries, so this list is what makes a network check possible — and it's the difference between confirming coverage in ten minutes and discovering a gap in February. Include anyone you see once a year; those are the ones that get forgotten.

3. Your current plan's paperwork

If you're on a Medicare Advantage or Part D plan, your plan mails an Annual Notice of Change in the fall listing what changes January 1 — premium, cost sharing, drug list, network. If you're on a marketplace plan, your insurer sends a renewal notice with the same kind of information. Either document tells you whether you need to do anything at all, which is the point: for many people the answer is no, and knowing that quickly is worth as much as switching.

4. Next year's income estimate

Marketplace savings are based on the income you expect for the coming coverage year, so an application will ask for a number. Healthcare.gov's get-ready-to-apply checklist lists what the application actually needs. On the Medicare side the income question runs backward — the income-related premium adjustment is set from an earlier tax year — and we compared the two clocks in one income number, two systems. If a household touches both, note any one-time income events from recent years too.

Then the dates take care of themselves

With those four in one place, the fall becomes a checking exercise rather than a research project. Read the notice when it arrives, compare the drug list against list one, run the network check against list two, and confirm the income figure. If everything still fits, doing nothing is a legitimate outcome and keeps your current coverage.

Statutory windows are the same everywhere, but deadlines for January 1 coverage vary by state on the marketplace side, so it's worth confirming your own state's dates before you plan around them. When you're ready to compare — or just want a second read on whether your current plan still fits — a licensed agent can go through it with you, free and with no pressure.
