The 2027 changes CMS has confirmed
CMS has finalized several Medicare Advantage and Part D policies for 2027. For consumers, the most concrete national figures available now are in the Part D defined standard benefit: a $700 deductible and a $2,400 annual out-of-pocket threshold for covered Part D drugs that count toward that threshold.
CMS also codified the redesigned Part D structure for 2027 and later years, including no enrollee cost sharing for covered Part D drugs in the catastrophic phase. These national rules do not make every plan identical, and they are not a quote of what any one person will pay.
- Defined-standard Part D deductible: $700 for 2027.
- Part D annual out-of-pocket threshold: $2,400 for 2027.
- Negotiated prices for 15 additional selected Part D drugs take effect January 1, 2027.
- The Medicare GLP-1 Bridge demonstration is scheduled to continue through December 31, 2027 for people who meet CMS eligibility rules.
What is not ready for a personal comparison yet
A national rule is not the same as a local plan design. A person’s 2027 premium, deductible, drug list, pharmacy network, provider network, referrals, copayments, coinsurance, supplemental benefits, and prior-authorization rules depend on the coverage available to that individual and the plan documents for 2027.
Medicare.gov was still displaying 2026 Part A and Part B cost figures when this page was reviewed on August 14, 2026. Boyd Financial Group therefore does not publish an estimate for 2027 Part A or Part B premiums, deductibles, or coinsurance.
If a 2027 figure is not in a current CMS, Medicare.gov, or official plan document, treat it as unconfirmed—not as a planning number.
What to watch for this fall
If you are already enrolled in a Medicare health or drug plan, review the Annual Notice of Change and Evidence of Coverage your plan provides in the fall. Those documents explain changes that apply to your plan in January.
Medicare Open Enrollment runs October 15 through December 7. Changes made during that period generally take effect January 1, provided the enrollment request is received by the deadline. Eligibility and other election periods depend on individual circumstances.
- Read the Annual Notice of Change instead of assuming current benefits continue unchanged.
- Check every prescription, dosage, tier, restriction, and pharmacy you use.
- Confirm providers and facilities directly; do not rely on last year’s network.
- Compare total expected costs, not one premium or benefit in isolation.
