See the three plan stages, the 2025 $2,000 out-of-pocket cap, and why the donut hole disappeared - explained by a Medicare expert.","totalDurationSeconds":388,"difficulty":"easy","tools":[],"materials":[],"steps":[{"number":1,"title":"Step 1: Understand What Medicare Part D Actually Covers","text":"Medicare Part D is the part of Medicare that pays for your prescription drugs. You can buy it two ways: as a standalone drug plan that sits next to Original Medicare (Parts A and B), or as a built-in drug benefit inside a Medicare Advantage plan. Watch the intro at 0:22. Private insurance companies sell every Part D plan, but each one has to meet a minimum federal standard. The structure works the same way either way. If you take any regular prescription, you almost certainly want Part D - going without it can mean a permanent late-enrollment penalty plus full retail prices at the pharmacy."},{"number":2,"title":"Step 2: Learn the Three Stages Every Part D Plan Uses","text":"Every Part D plan in 2025 and beyond runs through the same three stages in this order: the deductible, the initial coverage stage, and catastrophic coverage. Watch the breakdown at 0:54. Medicare sets the dollar limits for each stage every year. Insurance companies can offer richer benefits than the federal minimum, but never weaker. Knowing which stage you are in tells you exactly what you will pay at the pharmacy that day. The stages reset every January 1, so your spending counter starts over each year."},{"number":3,"title":"Step 3: Pay the Deductible First","text":"Stage one is the deductible - the amount you pay out of pocket on medications before the plan starts sharing the cost. In 2025 the maximum deductible Medicare allows is $590, and most plans set it at exactly that number. Watch the example at 1:36. Some plans waive the deductible entirely or apply it only to higher drug tiers. A plan with no deductible is not automatically the cheapest option - those plans often charge higher copays or premiums to make up for it. If you mostly take cheap generics, look for a plan that applies the deductible only to tiers 3, 4, and 5. You will get tier 1 and 2 drugs from day one at just the regular copay."},{"number":4,"title":"Step 4: Move to the Initial Coverage Stage","text":"Once you satisfy the deductible, you move to stage two - the initial coverage stage. Here you pay copays or coinsurance for each prescription based on which tier the drug sits in. Watch the tier walkthrough at 3:09. Every plan has a formulary that sorts covered drugs into five (sometimes six) tiers: preferred generic, non-preferred generic, preferred brand, non-preferred brand, and specialty. Insulin is capped at $35 by law, no matter the tier. A typical plan might charge $5 for tier 1 generics, $10 for non-preferred generics, $40 for preferred brand drugs, and a percentage (often 25-33%) of the cost for tier 5 specialty drugs. You stay in this stage until your total drug spending hits the catastrophic threshold."},{"number":5,"title":"Step 5: Reach Catastrophic Coverage if Your Spending Gets High","text":"Stage three kicks in once your total drug spending for the year crosses Medicare's annual limit. Watch this stage at 4:35. From that point on, your Part D carrier pays 100% of your medication costs for the rest of the calendar year. You pay nothing else for covered drugs until January 1. This is the safety net that protects you from a runaway prescription bill, and it is the single best reason to be enrolled in Part D even if you do not take expensive drugs today. One new diagnosis, one new specialty medication, and you would otherwise be on the hook for tens of thousands of dollars a year."},{"number":6,"title":"Step 6: Know the New 2025 $2,000 Out-of-Pocket Cap","text":"In 2025 the limit that triggers catastrophic coverage drops to $2,000 a year. That is a huge change from 2024, when the out-of-pocket threshold was closer to $8,000. Watch the explanation at 5:04. Once you have spent $2,000 of your own money on covered Part D drugs in a calendar year, you pay nothing for those drugs the rest of the year. If you take an expensive specialty drug, this single change could save you thousands of dollars. Medicare also added a new Part D Payment Plan in 2025 that lets you spread that $2,000 out over the year in monthly installments instead of paying it all up front in January and February."},{"number":7,"title":"Step 7: Forget the Donut Hole","text":"Starting in 2025, the coverage gap (better known as the donut hole) is gone. Watch the wrap-up at 5:43. For years, Part D dropped you into a stretch of higher costs partway through the year, right after you came out of initial coverage and before catastrophic kicked in. You now move from the deductible to the initial coverage stage to catastrophic coverage with no surprise gap in between. If a family member still talks about the donut hole, you can tell them it is officially history. The three-stage structure is now simpler and more predictable than it has been in twenty years."},{"number":8,"title":"Step 8: Check Your Medicare Advantage Plan's Drug Spending Limit","text":"If your drug coverage comes through a Medicare Advantage plan instead of a standalone Part D plan, watch the fine print. Watch this part at 5:20. The plan's overall maximum out-of-pocket limit only covers Part A and Part B services - inpatient care, outpatient care, doctor visits. Your Part D drug costs run on a separate tab with their own $2,000 cap. Treat the two limits as two different budgets, not one combined total. If you are choosing between a standalone Part D plan and an MA plan with built-in drug coverage, the three Part D stages and the $2,000 cap work the same way - the difference is whether you pay one premium or two, and whether your medical and drug coverage come from the same insurance company."}],"recipe":null,"lastUpdated":"2026-05-31T15:20:40.228Z","published":"2026-05-31T15:20:16.195Z","license":"CC BY 4.0.
