Medicare has released the standard prescription-drug cost limits for 2027, and both headline numbers are going up. The maximum standard Part D deductible will rise to $700, while the annual out-of-pocket threshold for covered Part D drugs will increase to $2,400.
Those figures are useful planning markers, but they do not tell you what a specific plan will charge or whether it will cover your prescriptions at your preferred pharmacy. Final 2027 plan offerings and average premiums are due in September. For Michigan beneficiaries, August is the right time to organize a drug list so the fall comparison is based on real medication needs.
The 2027 Medicare Part D numbers
The Centers for Medicare & Medicaid Services’ 2027 rate announcement sets these parameters for the defined standard Part D benefit:
- Maximum standard deductible: $700, up from $615 in 2026.
- Annual out-of-pocket threshold: $2,400, up from $2,100 in 2026.
- Catastrophic phase cost sharing: $0 for covered Part D drugs after the threshold is reached.
A plan may set a deductible below the standard maximum, including no deductible, and cost sharing varies by medication and plan design. Premiums do not count toward the $2,400 out-of-pocket threshold.
The $41.33 figure is not your final premium
CMS also announced a 2027 national base beneficiary premium of $41.33. That number feeds a federal formula; it is not a promise that every Part D plan will cost $41.33 per month. Your actual premium can differ by plan and may also include an income-related adjustment or a late-enrollment penalty.
CMS said in its July 28 Part D update that final average premiums and plan information will arrive in September. Comparing plans before those details appear would mean working with incomplete information.
Why an annual Part D review still matters
Each Medicare drug plan has its own formulary, pharmacy network, tiers, and coverage rules. A plan that worked well in 2026 can change its premium, move a medication to another tier, add prior authorization, or change which pharmacies offer preferred pricing for 2027.
Your own prescriptions can change too. A fair comparison should use the exact drug name, dosage, quantity, and refill schedule for every medication you expect to take next year. Then compare the estimated annual cost, not the premium alone.
What to collect before open enrollment
- Your current plan’s Annual Notice of Change, which usually arrives before the fall enrollment period.
- A current prescription list with drug names, dosages, quantities, and refill frequency.
- The retail and mail-order pharmacies you would realistically use.
- Any recent notice about prior authorization, step therapy, quantity limits, or a drug leaving the formulary.
- Your expected 2027 medical coverage, including whether you plan to keep Original Medicare with a supplement or use another Medicare option.
Part D and Medicare supplements handle different costs
Medicare supplement insurance helps with certain out-of-pocket costs under Original Medicare Parts A and B. It does not replace Part D drug coverage. Medicare.gov notes that supplement policies sold after 2005 do not include prescription-drug coverage, so many people with Original Medicare pair a supplement with a separate Part D plan.
That distinction matters during a review. Changing a drug plan is different from changing a Medicare supplement, and the enrollment protections and underwriting rules may differ. Do not cancel an existing policy until you understand the replacement coverage and effective date.
Mark October 15 through December 7
Medicare’s annual open enrollment period runs from October 15 through December 7. During that window, beneficiaries can review and change Medicare Advantage or Part D coverage for January 1. The Michigan Department of Insurance and Financial Services also recommends reviewing plan changes and available options each year.
