The Medicare Letter You Shouldn't Toss: Your Annual Notice of Change

Every September, Medicare plans mail a document called the Annual Notice of Change, or ANOC. Most people glance at it and set it aside. That one habit costs Florida seniors more money than almost anything else in Medicare, because the ANOC is the plan telling you, in writing, exactly what is getting more expensive next year.

What the ANOC actually is

If you have a Medicare Advantage or Part D plan, your insurance company is required to send you an ANOC before the Annual Enrollment Period. It compares your current year's coverage to next year's, side by side. It usually arrives by late September, ahead of the enrollment window that runs October 15 through December 7.

In plain English: the ANOC is not junk mail. It is a preview of what you will pay and what will be covered starting January 1, while you still have time to switch.

The five things to check first

You do not need to read all 30 pages. Look for these, and compare "this year" against "next year":

✓Monthly premium. Did it go up? A plan that was $0 can add a premium.
✓Copays for the care you use. Primary care, specialists, urgent care, and hospital stays are the ones that add up.
✓Drug coverage. Check whether your prescriptions moved to a higher tier or dropped off the formulary entirely.
✓Maximum out-of-pocket (MOOP). This is your worst-case medical spending for the year. Lower is better protection.
✓Extra benefits. Dental, vision, hearing, and grocery or over-the-counter allowances often shrink quietly.

The trap: doing nothing

If you ignore the ANOC and take no action, your plan does not simply stay the same. It rolls into next year's version, on the plan's new terms, not yours. That means the higher copays and changed drug list become your reality automatically. In some cases, if a plan leaves your county, doing nothing lands you back on Original Medicare with no drug coverage, which can trigger a late penalty later.

One more thing to verify: your doctors

The ANOC covers costs and benefits, but not always your specific providers. Provider networks are renegotiated every year, so even a plan that looks unchanged on paper may have dropped your doctor or preferred hospital. Call your doctor's office and confirm they take your 2026 plan, or ask us to check for you.

A simple fall routine

Late September: when the ANOC arrives, spend ten minutes on the five items above.
October: if anything important changed, list your doctors and drugs and compare other plans in your county.
Before December 7: make your choice during the Annual Enrollment Period so it takes effect January 1.

This is exactly the kind of annual check we do with our clients, so a stressful December letter becomes a ten-minute phone call. New to all of this? Start with Medicare explained simply or the year's 2026 Medicare changes.
