-
$103,000 or less (individual) / $206,000 or less (joint): No IRMAA
-
$103,001–$129,000 / $206,001–$258,000: +$12.90/month
-
$129,001–$161,000 / $258,001–$322,000: +$33.30/month
-
$161,001–$193,000 / $322,001–$386,000: +$53.80/month
-
$193,001–$499,999 / $386,001–$749,999: +$74.20/month
-
$500,000 and above / $750,000 and above: +$81.00/month
These surcharges are automatically deducted from your Social Security benefit if applicable.
Medicare Part D Plans: Basic vs Enhanced
Key Differences
There are two types of Part D plans:
-
Basic plans – Cover drugs listed in the Medicare formulary at a standard level.
-
Enhanced plans – May include additional coverage for drugs not covered by basic plans, have a lower deductible, or offer reduced copays.
Premium Ranges in 2025
-
Basic plans: Tend to have lower premiums but higher out-of-pocket costs
-
Enhanced plans: Offer broader coverage and cost more monthly
In 2025, enhanced plans are expected to average $75–$120 per month.
Changes in 2025 Medicare Part D Coverage Phases
Initial Coverage Phase
You pay your deductible, then share drug costs with your plan. This continues until your total drug costs reach $5,030.
Coverage Gap (Donut Hole)
In 2025, the coverage gap will have been effectively eliminated, thanks to the IRA. You will no longer be responsible for the 25% coinsurance for brand-name and generic drugs beyond the initial threshold.
Catastrophic Coverage Phase
In 2025, catastrophic coverage is replaced by a $2,000 annual out-of-pocket cap. After reaching this limit, you pay nothing for the rest of the year, a major change from prior years when you had to continue paying 5% of drug costs.
What Impacts Your Medicare Part D Premium?
Location
Premiums vary by state and even ZIP code due to regional differences in plan availability and competition.
Plan Selection
Each insurance provider sets its own premium. Plans with broader formularies, fewer restrictions, and more pharmacy options tend to cost more.
Income and Subsidies
As mentioned, higher incomes mean IRMAA surcharges. Conversely, low-income subsidies (Extra Help) can reduce or even eliminate premiums and deductibles.
