The monthly premium is rounded to the nearest $0.10 and added to your monthly Part D premium.

Deductible<\/span><\/h2>\n

How much do you have to pay out of pocket before Medicare Part D coverage starts?<\/b><\/p>\n

The cost of your Medicare Part D deductible varies depending on your drug plan. In 2026, the highest deductible price was $615, an increase from $590 in 2025. However, not all plans have a deductible.<\/span><\/p>\n

Premiums<\/span><\/h2>\n

How much does Medicare Part D cost per month?<\/b><\/p>\n

Since not everyone needs prescription drugs, Medicare prescription drug coverage is optional.\u00a0<\/span><\/p>\n

For those with a Part D plan, you may have to pay a monthly premium.\u00a0<\/span><\/p>\n

The Part D national base beneficiary premium (or the amount Part D plans start at) can change yearly. In 2026, the national base beneficiary premium is $38.99 per month for each Part D beneficiary.\u00a0<\/span><\/p>\n

There is also a Part D income-related monthly adjustment amount, or IRMAA, meaning that people with higher incomes may have to<\/span> pay more<\/span><\/a> according to their most recent tax return.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Copays and coinsurance<\/span><\/h2>\n

How much does Medicare Part D cost per drug?<\/b><\/p>\n

A copayment, or copay,<\/span><\/a> is a set amount (for instance, $10) that you pay for a prescription each time you get it filled, while your Part D plan pays for the rest.\u00a0<\/span><\/p>\n

Coinsurance means that you pay a percentage of the cost (for instance, 25%) of the drug each time you fill it, while the plan pays the rest.\u00a0<\/span><\/p>\n

Cost-sharing is set by each plan, and some plans have different copays or coinsurance for generic drugs and brand-name drugs. Each drug is assigned a tier on <\/span>your plan\u2019s drug formulary<\/span><\/a>. The lower the tier, the cheaper the copay or coinsurance will be. Brand-name drugs are often included in more expensive, higher tiers.<\/span><\/p>\n

Once you spend $2,100 on out-of-pocket costs, you\u2019ll enter the<\/span> catastrophic coverage stage<\/span><\/a>, and you\u2019ll pay no further cost-sharing.<\/span><\/p>\n

Late enrollment penalties<\/span><\/h3>\n

A less obvious plan cost that some people get stuck with is the <\/span>late enrollment penalty<\/span><\/a>, which affects anyone who doesn\u2019t opt for a Medicare Part D plan within their seven-month initial <\/span>Open Enrollment Period<\/span><\/a> but then decides to enroll in Part D later. The penalty, which is a percentage of the Part D national base beneficiary premium, goes up for each month you go without prescription drug coverage, and you will have to pay it for the life of your Part D drug plan, except for the following reasons:\u00a0<\/span><\/p>\n
