CMS Finalizes 2.48% Medicare Advantage Rate Hike for 2027, Easing Insurer Concerns

CMS has finalized a 2.48% net payment increase for 2027 Medicare Advantage plans, a significant upward revision from the initial 0.09% proposal, providing relief to insurers.

The increase was primarily driven by a higher Effective Growth Rate (EGR) based on updated data and a more favorable risk score normalization adjustment, which together added over 2.5 percentage points compared to the draft.

Despite the rate hike, CMS is tightening payment accuracy by excluding certain chart-review diagnoses from risk scores, aiming to balance insurer stability with long-term program sustainability.

The U.S. government has finalized a significant payment increase for private Medicare plans, offering a dose of relief to health insurers.

The Centers for Medicare & Medicaid Services (CMS) announced a final average payment increase of 2.48% for Medicare Advantage (MA) plans in 2027. This figure is a notable improvement from the minimal 0.09% increase proposed in January, a change that sent health insurance stocks like Humana and UnitedHealth rallying as it eased concerns about financial pressure on the industry.

So, what caused this significant shift? The decision was driven by two main technical factors. First, the Effective Growth Rate (EGR), which predicts per-person Medicare spending, was revised upward to 5.33% based on more recent healthcare cost data. Second, the adjustment for risk score normalization was less severe than initially projected. This factor accounts for differences in coding practices between MA plans and traditional Medicare, and the gentler adjustment gave insurers more breathing room. Together, these changes turned a near-freeze into a meaningful increase.

This final decision didn't happen in a vacuum, of course. Back in January 2026, CMS's initial proposal of a 0.09% increase caused a sharp market selloff and drew intense pushback from the insurance industry. They warned that such a low rate would force them to cut benefits, raise premiums, or even exit certain markets, potentially disrupting care for millions of seniors. This pressure, combined with updated economic data, likely encouraged CMS to find a middle ground.

However, this isn't just a win for insurers. CMS is playing a careful balancing act. While providing short-term stability with the rate hike, it is also pushing forward with long-term goals of ensuring 'payment accuracy' and program sustainability. A key part of this is a new rule that excludes diagnoses sourced only from chart reviews without a corresponding clinical encounter from risk calculations. This move, supported by research from groups like MedPAC highlighting billions in overpayments, aims to curb the practice of 'upcoding' where plans might make beneficiaries appear sicker on paper to receive higher payments.

In essence, the 2027 rate announcement reflects a compromise. It provides enough funding to maintain stability in the MA market for the upcoming year while simultaneously implementing stricter rules to protect taxpayer money and ensure the long-term health of the Medicare program.

Medicare Advantage (MA): Private health insurance plans approved by Medicare that are run by private companies. They provide Medicare Part A (Hospital Insurance) and Part B (Medical Insurance) coverage.
CMS (Centers for Medicare & Medicaid Services): The U.S. federal agency that administers the Medicare program and works in partnership with state governments to administer Medicaid.
Risk Score Normalization: An adjustment made to account for the fact that MA plans tend to record more diagnoses than traditional Medicare, which can inflate payments. The normalization factor aims to align payments with what costs would have been in the traditional system.
