2027 Medicare Numbers
2027 Medicare numbers: every figure, and whether it is final
Medicare's 2027 figures do not arrive all at once: they land across roughly seven months, from a rate announcement in April to a premium announcement in November. This page tracks every one of them, tagged by how certain it actually is, updated on every CMS and SSA release.
In short: Many figures below are tagged FINAL: a federal agency has already published them, including the Part D deductible, the Part D out-of-pocket cap, the Part D base premium, the Social Security COLA, and the Medigap high-deductible amount. The Part B premium and deductible, and every Part A figure, are PROJECTED from the June 2026 Trustees Report, since CMS has not announced them. The IRMAA income thresholds are determined by formula; CMS confirms them with the Part B announcement in November.
Every figure on this page carries one of four states: FINAL (a federal agency has published it), LOCKED BY FORMULA (determined by a calculation with published inputs, not yet formally announced), PROJECTED (a forecast, attributed to its source, subject to change), or AWAITING (not yet knowable, the expected date is given).
Part D: final
In short: Part D is the one part of 2027 that is genuinely settled. All three headline numbers are published.
| Figure | 2026 | 2027 | State | Source |
|---|---|---|---|---|
| Standard annual deductible | $615 | $700 | FINAL | CMS CY2027 Rate Announcement |
| Annual out-of-pocket cap | $2,100 | $2,400 | FINAL | CMS CY2027 Rate Announcement |
| National base beneficiary premium | $38.99 | $41.33 | FINAL | CMS Part D 2027 NAMBA fact sheet |
| National average monthly bid (NAMBA) | $239.27 | $296.05 | FINAL | CMS Part D 2027 NAMBA fact sheet |
| Premium Stabilization Demonstration | active | ends after CY2026 | FINAL | CMS Part D 2027 NAMBA fact sheet |
The base beneficiary premium at $41.33 is not a coincidence. It is $38.99 multiplied by 1.06, which rounds to $41.33, since the Inflation Reduction Act caps annual growth in that figure at 6% through 2029, and 2027 lands precisely on the cap. The NAMBA jump of 23.7% is the number to watch, because the base premium was held to 6% by statute while the underlying bid rose almost four times that fast. That gap has to show up somewhere, and where it shows up is plan-level premiums (see 2027 Part D premium changes).
Part B: projected
In short: Two numbers from the Trustees Report, neither announced by CMS.
| Figure | 2026 | 2027 | State |
|---|---|---|---|
| Standard monthly premium | $202.90/mo | $209.50/mo | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Annual deductible | $283 | $292 | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
CMS announces the final figures in the fall. The recent record: November 14, 2025 for the 2026 numbers, November 8, 2024 for 2025, October 12, 2023 for 2024, and September 27, 2022 for 2023. Full detail, including the hold-harmless mechanics and a competing higher figure in circulation: the 2027 Part B premium page.
IRMAA: projected, locked by formula on September 11
In short: The thresholds are a calculation, and eleven of the twelve inputs are published.
| Threshold | Single filer | Married filing jointly | State |
|---|---|---|---|
| Standard premium, no surcharge | up to $112,000 | up to $224,000 | PROJECTEDper Internal calculation (BLS CPI-U + statutory formula), Aug 12, 2026 |
| Tier 2 begins | $141,000 | $282,000 | LOCKED BY FORMULAexpected Nov 30, 2026 |
| Tier 3 begins | $176,000 | $352,000 | LOCKED BY FORMULAexpected Nov 30, 2026 |
| Tier 4 begins | $212,000 | $424,000 | LOCKED BY FORMULAexpected Nov 30, 2026 |
| Top tier begins | $500,000 | $750,000 | FINAL |
Based on your 2025 tax return. The last inflation input publishes September 11, 2026, after which every threshold is arithmetic. Method, flip points, and the SSA-44 reduction path: the 2027 IRMAA brackets page.
Part A: projected, not announced
In short: CMS has announced nothing, but the Trustees Report carries a full projected set that almost nobody is publishing.
| Figure | 2026 (final) | 2027 (projected) | State |
|---|---|---|---|
| Inpatient hospital deductible, per benefit period | $1,736 | $1,788 | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Daily coinsurance, days 61 to 90 | $434/day | $447/day | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Lifetime reserve day coinsurance | $868/day | $894/day | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Skilled nursing coinsurance, days 21 to 100 | $217/day | $223.50/day | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Part A premium, fewer than 30 quarters | $565/mo | $600/mo | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
| Part A premium, 30 to 39 quarters | $311/mo | $330/mo | PROJECTEDper Medicare Trustees Report, Jun 9, 2026 |
Source: 2026 Medicare Trustees Report, Table V.E1, intermediate estimates. The report states plainly that "the values listed in the table for future years are estimates, and the actual amounts are likely to be somewhat different as experience emerges." Three of these are statutory fractions of the inpatient deductible: days 61 through 90 cost one quarter of the deductible, lifetime reserve days cost one half, and skilled nursing days 21 through 100 cost one eighth.
Medicare Advantage: final, on the payment side
In short: What CMS pays plans for 2027 is settled. Each plan's 2027 premium and benefits are on Medicare.gov.
| Figure | 2027 | State |
|---|---|---|
| Effective growth rate | 5.33% | FINAL |
| Expected average payment change | +2.48% | FINAL |
| Plan premiums and benefits | set by each plan | FINAL |
The Advance Notice on January 26, 2026 proposed an average payment change of just 0.09%. The final on April 6 came in at 2.48%. Nearly the entire swing came from one line, the risk model revision and normalization adjustment moving from down 3.32% to down 1.12%.
Medigap and Social Security COLA: final
In short: Both were published in October 2026.
| Figure | 2026 | 2027 | State |
|---|---|---|---|
| Medigap high-deductible Plan F/G/J deductible | $2,950 | $3,050 | FINAL |
| Social Security cost-of-living adjustment | 2.8% | 3.6% | FINAL |
SSA announced the 2027 COLA on October 14, 2026. Social Security checks go up starting in January 2027. CMS announced the Medigap high-deductible amount in October 2026; it applies to high-deductible Plans F, G, and J starting January 1, 2027. COLA detail: the 2027 COLA and your Medicare page.
Drug prices: final
In short: Negotiated prices for 15 drugs take effect January 1, 2027.
The second cycle of the Medicare Drug Price Negotiation Program covers 15 Part D drugs, with maximum fair prices announced November 25, 2025 and effective FINAL. CMS figures: about 5.3 million Part D enrollees used these drugs during 2024, accounting for $42.5 billion, roughly 15% of gross covered Part D drug costs.
