Why Is My Medication Covered This Year but Not Next Year?

What changed and what you can do about it

This is one of the most frustrating situations people run into with Medicare.

Everything is working fine. You go to the pharmacy, pick up your prescription, pay your normal copay, and move on with your day. No issues.

Then the new year rolls around.

You go to refill the exact same medication and suddenly the price is higher. Or worse, you’re told it’s not covered at all.

And the first question is always the same:“Why did this change? I didn’t change anything.”

It’s a fair question. But the reality is, your plan probably did.

Medicare drug coverage doesn’t stay the same from year to year. Even if you keep the exact same Part D or Medicare Advantage plan, the details inside that plan can change. And those changes can directly affect what you pay for your prescriptions.

The biggest reason this happens comes down to something called a formulary.

Every Medicare drug plan has a formulary, which is simply a list of medications the plan agrees to cover. That list is reviewed and updated every year.

Insurance companies work with drug manufacturers and pharmacy benefit managers to decide which medications they’ll cover and at what cost. Those decisions are based on pricing, availability of alternatives, and contract negotiations.

So even though your plan name stayed the same, the list of covered drugs may not have.

Sometimes your medication is removed from the formulary entirely. Other times it’s still covered, but it gets moved to a different tier.

That’s another piece that catches people off guard.

Most plans group medications into tiers. Lower tiers typically include generics with lower copays. Higher tiers include brand-name or specialty medications with higher costs.

If your medication moves up a tier, your cost goes up with it, even though it’s still technically covered.

We also see situations where a medication now requires prior authorization. That means your doctor has to get approval from the insurance company before the plan will cover it. Until that happens, it can look like the medication isn’t covered.

Another common change is step therapy. This means the plan requires you to try a lower-cost alternative before approving the medication you’ve been taking. From your perspective, nothing changed. From the plan’s perspective, they want you to try a different option first.

And then there’s the pharmacy.

Some plans use preferred pharmacy networks. That means certain pharmacies offer lower pricing under your plan. If your pharmacy is no longer preferred, your cost can go up even if everything else stays the same.

When you put all of this together, it starts to make more sense. It’s not that Medicare suddenly stopped covering your medication. It’s that your specific plan made changes behind the scenes.

The challenge is that most people don’t realize these changes are coming.

Every fall, your plan sends out an Annual Notice of Change. It outlines what’s changing for the upcoming year, including premiums, deductibles, and drug coverage.

The problem is, most people don’t read it closely. Or they assume nothing will affect them. Then January hits, and they find out at the pharmacy counter. The good news is, this is something you can stay ahead of.

The best time to catch these changes is during the Annual Enrollment Period, from October 15 through December 7.

That’s your opportunity to review your current plan, check your medications against next year’s coverage, and see if a different plan might be a better fit.

Even if you’ve had the same plan for years, it’s worth reviewing. Plans change. Drug coverage changes. And sometimes a small adjustment can save you a significant amount of money.

If you’re already dealing with a medication that’s no longer covered or has become too expensive, you still have options.

Your doctor may be able to prescribe a covered alternative. In some cases, they can request an exception from the insurance company. There may also be manufacturer discounts or assistance programs available.

It’s not always a perfect fix, but you’re not stuck.

At the end of the day, Medicare drug plans are designed to change each year. What worked perfectly one year may look different the next.

If you’ve run into this and aren’t sure what changed or what to do next, reach out. We can walk through your plan, review your medications, and help you find the best path forward.

Because no one likes being surprised at the pharmacy counter. And with a little planning, you can usually avoid it.
