Seniors enrolled in Medicare Advantage plans are absorbing sharply higher potential costs at the worst possible moment: out-of-pocket maximums have risen by roughly $900 over two years, and supplemental benefits in categories such as dental, vision, transportation, and meals have thinned out across plan offerings heading into 2026. The shift is visible in federal data covering contract years 2024 through 2027, and it coincides with the end of a federal model that had given plans extra flexibility to target cost-sharing relief to the sickest enrollees.
Rising MOOP ceilings and shrinking extras hit beneficiaries at once
The financial exposure facing Medicare Advantage enrollees has grown measurably. CMS publishes official MOOP calculations for each contract year, and the agency’s downloads covering CY 2024 through CY 2027 show the allowable ceiling climbing steadily. That upward drift means a beneficiary who hits the maximum in a high-cost year could owe hundreds of dollars more than a similarly situated enrollee would have paid just two plan years earlier.
The increase does not exist in isolation. Plan Benefit Package data maintained by CMS, available through the agency’s benefits files, allows year-over-year comparison of what plans actually offer. Comparing the 2024 Q1 benefits file with the 2026 file reveals fewer plans packaging supplemental benefits in dental, vision, transportation, and meal categories. Those extras had been a major selling point that distinguished Medicare Advantage from traditional fee-for-service Medicare, so their pullback changes the value calculation for millions of enrollees.
The 2026 Plan Benefit Package release, accessible through CMS’s dedicated 2026 benefits dataset, underscores how the mix of offerings is shifting. While some plans still advertise rich supplemental packages, others have pared back coverage limits, tightened eligibility criteria, or dropped certain extras entirely. For beneficiaries, the headline promise of “dental and vision included” increasingly masks a patchwork of narrower networks, lower annual caps, and fewer covered services.
One structural question is whether plans are raising MOOP levels primarily because medical costs are rising or because higher ceilings give insurers room to stay compliant with medical-loss-ratio rules while trimming the benefits that cost them the most. Under CMS rules, when a plan bids below the benchmark payment rate, the resulting rebate dollars must be used to offer supplemental benefits, reduce cost sharing, reduce Part D premiums, or reduce Part B premiums, according to a CMS fact sheet on 2025 program stability. Plans that shift rebate spending away from generous supplemental packages and toward slightly lower premiums or narrower cost-sharing reductions can still meet the letter of the requirement while exposing enrollees to higher out-of-pocket risk through elevated MOOPs.
The combined effect is that beneficiaries face a more volatile cost landscape. A plan that looks affordable on monthly premiums may now carry a higher downside if an enrollee experiences a hospitalization, intensive post-acute care episode, or a year of expensive specialist visits. At the same time, the erosion of supplemental benefits means that services many seniors have come to rely on for routine needs – cleanings and fillings, eyeglasses, rides to appointments, or post-discharge meals – may no longer be as robustly covered as they were in earlier years.
VBID termination and federal data gaps cloud the 2026 outlook
The end of the Medicare Advantage Value-Based Insurance Design Model adds another variable. CMS confirmed that the VBID model terminated at the end of 2025, removing a testing framework that had allowed participating plans to tailor cost-sharing reductions and supplemental benefits to enrollees with specific chronic conditions. Without that flexibility, plans entering 2026 lost one tool for directing savings toward the enrollees most likely to incur high costs or face barriers to care.
VBID had encouraged insurers to experiment with targeted incentives: lowering copays for high-value medications, waiving cost sharing for particular specialists, or expanding supplemental services for people with conditions such as diabetes or congestive heart failure. Its conclusion means those customized arrangements now have to fit within standard Medicare Advantage benefit rules, potentially making them more expensive or administratively complex for plans to sustain. Some insurers may respond by scaling back the very targeted benefits that helped the sickest members stay stable and avoid hospitalizations.
At the same time, federal data releases offer only a partial window into how these changes will affect real-world spending for enrollees. The MOOP files show the maximum exposure, and the Plan Benefit Package datasets outline which services are covered and at what nominal cost sharing. But they do not capture how often beneficiaries actually hit those limits, how frequently they use supplemental benefits, or how changes in network design and utilization management might compound the impact of higher ceilings and thinner extras.
For policymakers, the convergence of higher MOOPs, leaner supplemental benefits, and the sunset of VBID raises questions about whether Medicare Advantage is delivering on its promise of predictable, comprehensive coverage. For beneficiaries and advocates, the near-term task is more practical: scrutinizing 2026 plan documents, comparing not just premiums but worst-case out-of-pocket exposure, and paying close attention to what has quietly disappeared from the list of “extras” that once set these plans apart.
