Understanding the 2026 Medicare Advantage Rate Announcement
In early April 2025, the Centers for Medicare & Medicaid Services (CMS) released its final 2026 Rate Announcement for Medicare Advantage (MA) and Part D plans [1.7.4]. The headline figure is a projected 5.06% effective increase in payments from the government to private insurance companies that offer MA plans [1.2.1, 1.2.3]. This translates to over $25 billion in additional payments to these plans for the 2026 calendar year [1.2.2].
It is crucial to understand that this is not a direct 5.06% increase in every beneficiary's monthly premium. Instead, it is the average rate change in the capitated payments insurers receive from Medicare to cover the cost of care for each enrollee [1.4.1]. This funding adjustment is influenced by several factors, including the growth in overall Medicare costs and updates to risk adjustment models [1.2.6]. The actual premiums that beneficiaries will see for 2026 plans will be announced in the fall of 2025, just ahead of the Open Enrollment period [1.7.6].
How Are MA Payment Rates Determined?
The process for calculating these rates is complex, revolving around a competitive bidding system against a government-set benchmark [1.4.4].
- Setting the Benchmark: CMS first calculates a benchmark for each county. This benchmark is based on the average cost of care for a beneficiary under Original Medicare (Parts A and B) in that specific area. It represents the maximum amount Medicare will pay an MA plan for an enrollee in that county [1.4.3, 1.4.5].
- Plan Bidding: Each insurance company submits a bid, which is their estimate of how much it will cost to provide Part A and Part B services to an average-health beneficiary in that county [1.4.1].
- Calculating Payments and Rebates:
- If a plan's bid is below the benchmark, the plan receives its bid amount plus a rebate from the savings. This rebate must be used to benefit the enrollee by offering lower premiums, reduced cost-sharing, or extra benefits like dental, vision, or hearing coverage [1.4.2, 1.4.7].
- If a plan's bid is above the benchmark, the plan receives the benchmark amount, and the beneficiary must pay the difference as a monthly premium [1.4.1].
- Risk Adjustment: The payment to the plan is then adjusted based on the health status of each individual enrollee. Plans receive higher payments for beneficiaries with more complex health conditions to cover their anticipated higher costs [1.4.4].
This system encourages insurers to operate efficiently and offer competitive benefit packages to attract enrollees.
Factors That Determine Your Personal MA Costs
While the CMS rate announcement sets the stage, your actual out-of-pocket costs depend on the specific plan you choose. Key variables include:
- Monthly Premium: Many MA plans offer a $0 monthly premium (you still must pay your Part B premium) [1.5.6]. For 2025, the average monthly MA premium was projected to be just $17.00 [1.3.4].
- Deductible: This is the amount you must pay for services before your plan starts to pay.
- Copayments and Coinsurance: These are the fixed amounts or percentages you pay for each service or prescription drug.
- Out-of-Pocket Maximum: All MA plans have an annual limit on your out-of-pocket costs for covered services. Once you reach this limit, the plan pays 100% for covered services for the rest of the year. For 2025, the maximum limit was set at $9,350 for in-network services, though many plans set a lower limit [1.5.2, 1.5.4].
- Provider Network: HMO plans generally require you to use in-network providers, while PPO plans allow out-of-network care, usually at a higher cost [1.5.1].
Comparison: Medicare Advantage vs. Original Medicare
Choosing between MA (Part C) and Original Medicare (Parts A & B) involves weighing costs, coverage, and flexibility. The following table highlights key differences based on 2025 data.
| Feature | Original Medicare | Medicare Advantage (Part C) |
|---|---|---|
| Monthly Premiums | Part A is usually premium-free. Part B premium is $185/month (in 2025) [1.3.7]. Requires separate Part D (drug) & Medigap plans, each with their own premium [1.5.4]. | Often has a $0 plan premium, but you still pay the Part B premium [1.5.6]. The average MA premium in 2025 was $17/month [1.3.4]. |
| Out-of-Pocket Limit | No annual limit on what you could spend, unless you purchase a separate Medigap policy [1.5.5]. | Yes, every plan has a yearly maximum out-of-pocket limit for covered services [1.5.2]. |
| Doctor & Hospital Choice | You can go to any doctor or hospital in the U.S. that accepts Medicare [1.5.6]. | You generally need to use doctors and hospitals in the plan's network (HMO, PPO) [1.5.1]. |
| Prescription Drugs | Not covered. Requires purchasing a separate Part D plan [1.5.5]. | Most plans include prescription drug coverage (these are called MA-PDs) [1.5.5]. |
| Extra Benefits | Does not cover routine dental, vision, or hearing services. | Most plans offer extra benefits like vision, hearing, dental, and fitness programs [1.5.2]. |
Finding Your Best Plan for 2026
With the 2026 payment structures finalized for insurers, they will now design their benefit packages and set premiums. These details will become public in the fall of 2025. The Medicare Open Enrollment Period, running from October 15 to December 7, is your annual opportunity to compare these new plans and make changes to your coverage.
To prepare, you should:
- Review your current coverage and how well it met your needs over the past year.
- Make a list of your doctors and prescription drugs to ensure they are covered by any new plan you consider.
- Use the official Medicare Plan Finder tool on the Medicare website once the 2026 plan information is released. It is the most comprehensive and authoritative resource available for comparing plans in your area.
Conclusion
The announced 5.06% increase in the Medicare Advantage rate for 2026 is a positive indicator of stable funding for the program, which now serves over half of all beneficiaries [1.6.1]. While this government payment rate provides a foundation, the actual cost to you will depend on the specific plan you select this fall. By understanding how the system works and what factors to compare, you can confidently navigate the upcoming Open Enrollment season and choose the best coverage for your health and budget.
