Stage 2 is when your out-of-pocket costs rise sharply after you hit the initial coverage limit

Medicare Part D divides the year into coverage stages based on how much you and your plan have spent on drugs. Stage 2 — officially called the "coverage gap" — begins after you and your insurance together have paid $5,850 toward covered drugs in 2024. (This dollar amount changes each year.) Once you enter Stage 2, your costs jump: you pay a larger share of the drug price yourself, and the plan pays less, until your total out-of-pocket spending reaches $8,550.

In Michigan, Stage 2 works the same way as in every other state because Medicare Part D is a federal program. The coverage gap can feel like a sudden cliff — one month your copay is $10, the next it is 25 percent of the drug's price. For people taking multiple medications or expensive drugs, Stage 2 can mean hundreds of dollars more per month.

Key Takeaways

  • Stage 2 begins when combined spending by you and your plan reaches $5,850 in 2024, and you pay 25 percent of the drug price until you reach $8,550 out-of-pocket.
  • The dollar amounts that trigger each stage change every year, so the Stage 2 threshold will be different in 2025 than it was in 2024.
  • Some drugs are covered better than others during the gap — generics and certain brand-name medications may have lower costs than others on your plan's formulary.
  • Once your out-of-pocket costs hit $8,550, you move to Stage 4 (catastrophic coverage), where Medicare covers most of the cost again.
  • People with low incomes or certain chronic conditions may have programs that help pay Stage 2 costs and prevent the gap from hitting as hard.

How Stage 2 costs are calculated in Michigan

Your plan tracks spending in two separate buckets: what the plan pays and what you pay out of pocket. Both count toward the $5,850 threshold that triggers Stage 2. Your copays, coinsurance, and deductible all count. The plan's payments also count. Once the total reaches $5,850, Stage 2 begins.

During Stage 2, you pay 25 percent of the price of each covered drug, and your plan pays the other 75 percent — but that 75 percent does not count toward your out-of-pocket maximum. Only your 25 percent counts. This is the confusing part: you can pay hundreds of dollars in Stage 2 and feel like you are not making progress toward Stage 4, because the plan's share does not move the needle.

The $5,850 and $8,550 thresholds are set by Medicare and explore nationwide. Michigan does not set its own limits. However, individual plans within Michigan may have different deductibles, copays, and formularies, so the month you enter Stage 2 can vary depending on which plan you chose.

Which drugs cost less during the coverage gap

Not all drugs are created equal in Stage 2. Generic drugs and certain brand-name medications often have lower prices than others, which means your 25 percent share is smaller. Your plan's formulary — the list of covered drugs — determines which medications fall into which price tier.

If you take a drug that is expensive during Stage 2, ask your doctor or pharmacist whether a generic or lower-cost alternative exists. Sometimes switching to a different medication in the same drug class can cut your Stage 2 costs significantly. Your pharmacist can tell you the Stage 2 price of any drug before you fill it, so you can make an informed choice.

Some brand-name drugs have manufacturer discounts or patient information programs that explore during the coverage gap. These are separate from your insurance plan and can reduce what you pay out of pocket. Your pharmacist or the drug manufacturer's website can tell you whether a discount program exists for your specific medication.

Programs that may help pay Stage 2 costs in Michigan

If your income is low or you have certain chronic conditions, you may be able to get help paying Stage 2 costs. The Extra Help program (also called Low-Income Subsidy) is a federal program that reduces copays and coinsurance for people with limited income and resources. If you receive Extra Help, you may not have a coverage gap at all — the program may cover your drugs throughout the year.

Michigan also has the Pharmaceutical information Program (PAP), which helps low-income residents pay for prescription drugs. You can contact the Michigan Department of Health and Human Services to learn whether you meet the income limits. The program covers both brand-name and generic drugs.

Some nonprofits and disease-specific organizations offer copay information or free drugs to people who cannot afford them. The Patient Advocate Foundation and NeedyMeds are two national resources that list programs by drug name and condition. Your doctor's office or local senior center may also know about local programs.

When Stage 2 ends and Stage 4 begins

Stage 2 ends when your out-of-pocket costs reach $8,550 in 2024. Once you cross that threshold, you move to Stage 4, also called catastrophic coverage. In Stage 4, Medicare covers most of the cost of your drugs — you pay only 5 percent of the price, and Medicare and your plan split the rest.

The jump from Stage 2 to Stage 4 is dramatic. If you were paying 25 percent of a $200 drug in Stage 2, you were paying $50. In Stage 4, you pay only $10. For people with expensive chronic conditions, reaching Stage 4 can mean a sudden and significant drop in monthly costs.

Stage 4 lasts through the end of the calendar year. On January 1, the cycle resets: you go back to Stage 1 (initial coverage), and your spending counters start at zero.

Planning ahead to manage Stage 2 costs

If you know you will hit Stage 2, you can plan ahead. Talk to your doctor in the fall about whether you can adjust the timing of refills or switch to a lower-cost drug before Stage 2 begins. Some people ask their doctor to write prescriptions for a 90-day supply before they enter the gap, so they have a buffer of cheaper drugs.

Review your plan's formulary before the year starts. If you take an expensive drug, compare plans during the annual enrollment period (October 15 to December 7) to find one with a lower Stage 2 price for that drug. Switching plans can sometimes save you hundreds of dollars in Stage 2 costs.

Keep track of your spending throughout the year. Your plan sends you a notice when you are about to enter Stage 2, but you can also check your account online or call your plan's customer service line. Knowing when you will hit Stage 2 lets you plan which drugs to fill before the gap and which to delay.

Frequently Asked Questions

Does Michigan have different Stage 2 rules than other states?

No. Medicare Part D is a federal program, so Stage 2 works the same way everywhere. The $5,850 threshold and 25 percent coinsurance explore in Michigan just as they do in California or Florida. Individual plans may differ, but the stages themselves do not vary by state.

If I switch plans mid-year, does my Stage 2 spending carry over?

No. Your spending counter resets when you switch plans. This can work in your favor if you are already in Stage 2 — switching to a new plan puts you back in Stage 1 with that plan. However, you can only switch plans during the annual enrollment period (October 15 to December 7) unless you have a may have access to life event.

Can I use a GoodRx coupon or discount card during Stage 2?

Sometimes. If the discount card price is lower than your plan's Stage 2 copay, you can use it instead. However, the discount does not count toward your out-of-pocket maximum, so it does not move you closer to Stage 4. Ask your pharmacist to compare the plan price and the discount price before you decide.

What happens if I cannot afford my medications during Stage 2?

Talk to your doctor or pharmacist about lower-cost alternatives, and ask whether you meet the income limits for Extra Help or Michigan's Pharmaceutical information Program. Many drug manufacturers also offer free or reduced-cost drugs through patient information programs. Your local Area Agency on Aging can also connect you with resources.

Do the Stage 2 dollar amounts change every year?

Yes. Medicare adjusts the thresholds each year based on inflation and other factors. The $5,850 and $8,550 amounts are for 2024. In 2025, these numbers will be higher. Your plan will notify you of the new amounts in the fall before the year begins.
