The Centers for Medicare & Medicaid Services (CMS) released the on January 26, 2026. The Advance Notice begins CMS鈥檚 annual rate-setting cycle and describes proposed updates to Medicare Advantage (MA) growth rates, benchmark rebasing, risk adjustment, Star Ratings, and Part D payment parameters. CMS previously released a鈥痠n November 2025 that included policy changes to the Star Ratings system and enrollment policies for MA and Part D starting in contract year 2027. (Read the 红领巾瓜报 (红领巾瓜报) summary here.)
Comments on听the Advance Notice are due February 25, 2026, and听CMS will publish the final CY 2027 rate announcement no later than April 6, 2026.听听
This article provides an early look at the proposed methodological updates and draft capitation rates. Wakely, an 红领巾瓜报 Company, will publish a detailed analysis of the Advance Notice in early February.
Payment Impact on Medicare Advantage Organizations
CMS estimates a national per capita MA growth rate of 5.10 percent from 2026 to 2027, with fee-for-service (FFS) non-end-stage renal disease (non-ESRD) growth of 5.10 percent and FFS dialysis end-stage renal disease (ESRD) growth of 6.17 percent.
The听5.10听percent growth rate reflects projected increases in per听capita听FFS听Medicare spending for beneficiaries who are听aged/have听disabilities听and serves as the primary driver of 2027 benchmark updates, interacting with rebasing and risk adjustment changes to听determine听final capitation payments.听The growth rate听reflects听updates听to听how CMS pays for skin substitutes听in the 2026 Medicare Physician听Fee听Schedule. These updates resulted in significantly lower projected costs听and materially reduced听the growth听rate.听
These preliminary estimates inform the development of MA benchmarks and may change in the final rate announcement.听

Medicare Advantage Benchmarks, Rebasing, and Risk Adjustment
The Advance Notice describes CMS鈥檚 approach and changes that will affect payment to plans, including:
- Excluding from the risk adjustment process diagnoses submitted from chart reviews with unlinked claim records. In the Fact Sheet, CMS estimates this change will reduce Part C payments by 1.53 percent.听
- Rebasing听county听FFS听rates for 2027 using 2020鈥2024 claims data, continuing听CMS鈥檚听practice of updating benchmarks annually to reflect the most current FFS experience. The Advance Notice also reiterates the statutory framework for calculating benchmarks, including applicable and specified amounts, benchmark caps, and quality bonus payments.听
- Updating听the CMS Hierarchical Condition Category (CMS-HCC) and Prescription Drug Hierarchical Condition Category (RxHCC) risk adjustment models and associated normalization factors for CY 2027 and听continuing听to apply the statutory MA coding pattern difference adjustment to account for systematic differences in diagnosis coding between MA and FFS.听
Quality Bonus Payments, Star Ratings, and Part D Updates
CMS states that contracts with 4 or more Stars receive a 5 percentage-point quality bonus, while new and low-enrollment contracts receive a 3.5percentage-point bonus. The Advance Notice also includes updates related to Part C and Part D Star Ratings measures and methodological refinements.
For Part D, CMS outlines proposed updates to the defined standard benefit parameters for CY 2027, as well as changes to Part D risk adjustment, normalization, premium stabilization, reinsurance, and risk-sharing, with additional policy context provided in the Contract Year 2027 Medicare Advantage and Part D proposed rule.
