What is the Part D deductible?
The amount you pay before the plan starts sharing costs, and why the tiers it applies to matter more than the number itself.
The Part D deductible is what you pay out of pocket for prescriptions before the plan begins sharing costs. It resets every January 1.
There is a federal maximum, not a fixed amount
Medicare sets a maximum deductible each year that no plan may exceed. Plans can charge less, and many do.
- Some plans charge the full allowable deductible and offer lower premiums in exchange
- Some charge a partial deductible
- Some charge none at all
The current year's maximum is set each January. Check Medicare.gov for the figure, or call and we will look it up.
The detail that matters more than the number
Many plans apply the deductible only to certain tiers. Generics on tiers 1 and 2 are often excluded, meaning those drugs are covered at their copay from January 1 while brand names wait until the deductible is met.
So a plan with a full deductible that exempts generics may cost you less than a plan with no deductible but higher copays, if all your medications are generic. Read which tiers the deductible applies to, not just the dollar amount.
Why January feels expensive
Your first fills of the year come while you are still paying toward the deductible, so a medication that costs a small copay in June can cost the full negotiated price in January.
This is normal and it is not an error. It is also why an expensive drug can produce a large bill in the first weeks of the year.
There is now an option to spread your out of pocket drug costs into level monthly payments across the year rather than paying them as they occur. It does not reduce the total, it smooths it. Ask your plan to opt in if a large January bill would be difficult.
How the deductible fits the whole year
- You pay the negotiated price until the deductible is met, on whichever tiers it applies to.
- Then you pay copays or coinsurance by tier.
- Once your out of pocket spending reaches the annual cap, covered drugs cost you nothing for the rest of the year.
See the annual cap and how tiers work.
If you qualify for Extra Help
Extra Help reduces or eliminates the deductible along with premiums and copays. If your income is limited it is worth applying before choosing a plan on deductible grounds.
See Extra Help.
How to compare plans on this
Do not compare deductibles directly. Run your actual medication list through the Plan Finder and sort by total estimated annual cost. That figure already accounts for the deductible, the tiers and the pharmacy, which is why it is the only comparison worth making.
Common follow-up questions
Does every plan have a deductible?
No. Plans can charge anywhere from nothing up to the federal maximum, and many charge less than the maximum.
Does the deductible apply to all my drugs?
Often not. Many plans exempt generic tiers, so those are covered at their copay from January 1.
Why did my January prescription cost so much?
You were likely paying toward the deductible. Ask your plan about spreading your out of pocket costs into level monthly payments.
