CMS has finalized two important 2027 Part D figures: the standard deductible is $700, up from $615 in 2026, and the annual out-of-pocket threshold is $2,400, up from $2,100 in 2026. These figures appear in Table V-2 on printed page 95 of the CMS April 6, 2026 Final Announcement.
Those amounts apply to the Part D prescription drug benefit. The out-of-pocket threshold concerns covered Part D drugs. It is not a cap on premiums, noncovered drugs, or all Medicare medical spending. A plan can use a deductible below the standard amount, and programs such as Extra Help can change what an enrollee pays.

What Has CMS Confirmed for Medicare Part D in 2027?
CMS finalized the 2027 standard Part D benefit parameters in its April 6, 2026 announcement. The standard deductible rises by $85, and the annual out-of-pocket threshold rises by $300. These are national benefit parameters, not a quote for a particular plan.
Plan details still matter. A plan may set a lower deductible, may apply different cost sharing by drug tier, and can have pharmacy networks, prior authorization, step therapy, and quantity limits. Check each medication by exact name and dosage, plus the pharmacy you use.
What Do the Part D Figures Not Cover?
The $2,400 threshold is not a single cap for everything a Medicare beneficiary spends. It does not include the plan premium, drugs the plan does not cover, or medical expenses under Part A, Part B, Medicare Advantage medical benefits, or Medigap. The $700 figure is the standard Part D deductible, but an individual plan can use a lower amount.
What About 2027 Part A, Part B, and IRMAA?
Part A premiums and cost sharing, the Part B premium and deductible, and IRMAA brackets are separate from the confirmed Part D figures above. This article does not state unverified 2027 dollar amounts or predict how much they will change. Use Medicare.gov's official costs page for currently confirmed figures.
What CMS Projects for the 2027 Medicare Advantage and Part D Market
In its September 28, 2026 landscape announcement, CMS said Medicare Advantage and Part D access is expected to remain stable nationally for 2027. Those figures are projections and national summaries, not confirmation that a particular carrier, premium, benefit, formulary, pharmacy, or provider network is available in your ZIP code.

Schedule My Medicare ReviewWhen Can You Review Coverage for January 1, 2027?
Medicare Annual Enrollment runs from October 15 through December 7, 2026. Changes made during this period generally take effect January 1, 2027. Plan availability, premiums, networks, formularies, and benefits are plan-specific, so review actual 2027 materials rather than assuming this year's plan will work the same way.
AEP applies to Medicare Advantage and Part D changes. It does not give everyone a guaranteed-issue right to switch Medigap policies. Outside a protected right or your federal Medigap Open Enrollment Period, medical underwriting may apply.
What Should You Bring to a 2027 Plan Review?
- Your current plan card and Annual Notice of Change.
- Every medication's exact name, dosage, and frequency.
- Your preferred pharmacy and any mail-order preference.
- Your doctors, hospitals, clinics, and other facilities.
- Your priorities for premiums, predictable costs, travel, and provider access.
Compare plan-specific annual costs, drug coverage, pharmacy status, and provider networks. Keeping current coverage can be the right result. A change should happen only when another option is suitable and you are eligible to enroll.
