Premiums, networks, and drug formularies change annually. A plan that fit perfectly last year can quietly become a poor deal. A quick annual review during Open Enrollment — checking your doctors, drugs, and total cost — keeps you in the right plan rather than the one you happened to pick before.
Here’s the uncomfortable truth about “keeping” your plan: the plan you renew in January is not the plan you enrolled in last year. Carriers adjust premiums, redraw networks, reshuffle drug formularies, and change copays every single year. Your plan sends you a notice describing next year’s changes — for Medicare plans it typically arrives in the fall, before the enrollment window opens. Most people never read it. The ones who do are the ones who don’t get surprised in January when a medication jumps tiers or a doctor quietly leaves the network.
Your life changes too. Income shifts move your subsidy math. New prescriptions change which formulary fits. A new diagnosis, a planned surgery, a child aging toward 26, a move — each one can flip which plan is genuinely cheapest for you. Multiply plan-side changes by life-side changes, and the odds that last year’s winner is still this year’s winner drop every year you skip the check.
Your plan tells you what’s changing next year. Fifteen minutes with this document is the highest-value reading you’ll do all year.
The window to join, switch, or drop Medicare Advantage and Part D plans for a January 1 start.
The window for individual and family marketplace plans — compare, switch, or re-confirm your current pick.
Changes take effect. If you did the review, you start the year in the plan that actually fits — not the one inertia chose.
A real annual review is shorter than most people fear. Check three things. Doctors: are your must-keep providers still in next year’s network? Drugs: is every prescription still on the formulary, and on the same tier? Total cost: not just the premium, but premium plus your expected copays, deductible, and worst-case out-of-pocket exposure. If all three come back clean, congratulations — keeping your plan is now a decision instead of a default. If any of them changed, you’ve just caught it while you can still do something about it.
On the marketplace side, the review has one extra step Medicare doesn’t: refresh your income estimate. Your premium credit is calculated from what you expect to earn in the coverage year, and letting an old number ride is how people end up either overpaying all year or owing a correction at tax time. New job, raise, side income, a dependent moving on or off your taxes — any of these changes the math, and Open Enrollment is the natural moment to true it up.
Say your blood pressure medication moves to a higher tier for next year. Caught in November, that’s a shrug — you compare plans during the window and switch to one that covers it better. Discovered at the pharmacy counter in February, it’s a year-long expense you mostly can’t undo until the next window. Same change, completely different outcome, and the only variable was when you looked.
The usual objection is some version of “switching sounds like a hassle.” It’s worth separating the review from the switch: reviewing costs you fifteen minutes and commits you to nothing. Most years, the review confirms you’re fine — and that confirmation has value, because now you know rather than hope. When the review does surface a problem, switching during the proper window is mostly paperwork the new plan and your advisor handle, your doctors don’t need to “approve” anything, and coverage hands off on a set date. The hassle people fear is largely a memory of how insurance used to work.
