Medicare beneficiaries face a critical decision regarding their healthcare coverage, choosing between the federally administered Traditional Medicare program and private Medicare Advantage (MA) plans, such as Health Maintenance Organizations (HMOs) or Preferred Provider Organizations (PPOs). These private plans operate under contracts with the federal government to deliver Medicare benefits to their enrolled members. The compensation received by insurers from Medicare is a fixed monthly sum per enrollee, which fluctuates based on factors like the county where the plan is offered, the health profile of its members, its quality star rating, and the projected expenses for covering Medicare Part A and Part B services.

The Financial Framework of Medicare Advantage

These private insurance entities utilize federal payments to cover Medicare-approved services, frequently extending their use to provide additional supplemental benefits and reduce cost-sharing for enrollees, features that significantly attract individuals. A key mechanism enabling plans to offer these extra advantages, often without imposing additional premiums for Part D prescription drugs or other supplemental benefits, is the "rebate" system. According to the Medicare Payment Advisory Commission (MedPAC), in 2026, plans receive an additional $2,664 per enrollee beyond their estimated expenditures for delivering Medicare-covered services. This rebate amount has witnessed substantial growth in recent years, more than doubling since 2018.

To further manage expenditures and fund these attractive supplemental benefits, plans employ various cost containment strategies, including prior authorization requirements and the establishment of provider networks. While prior authorization serves to verify the medical necessity of services before coverage, thereby mitigating unnecessary costs, it can also inadvertently create hurdles for beneficiaries seeking timely care. Furthermore, many Medicare Advantage plans feature restricted provider networks, which can limit an enrollee's selection of doctors and hospitals. A majority of Medicare Advantage participants, specifically over half, are enrolled in HMO plans that typically do not cover services rendered outside their approved network.

This analysis delves into the specifics of Medicare Advantage plans for 2026, examining aspects like premiums, out-of-pocket expenditure caps, supplementary benefits, and the role of prior authorization, alongside relevant historical trends.

Noteworthy Developments for 2026 Enrollment

For 2026, a significant three-quarters (75%) of individuals enrolled in individual Medicare Advantage plans that include prescription drug coverage are not required to pay any premium beyond their standard Medicare Part B premium. This zero-additional-premium offer stands as a compelling feature, particularly for those on fixed or modest incomes. The overall average supplemental premium, encompassing those plans with no additional cost, is $15 per month. Individual Medicare Advantage plans are broadly available to all beneficiaries with both Medicare Part A and Part B, differing from specialized plans like Special Needs Plans (SNPs) or group plans provided through employers or unions.

Regarding plan types, more than six out of ten individual Medicare Advantage enrollees with prescription drug coverage (61%) are in HMOs in 2026. Local PPOs account for 38% of enrollees, while regional PPOs represent less than 1%. HMOs typically restrict coverage to in-network services but generally feature lower supplemental premiums, averaging $12 per month in 2026. Conversely, PPOs offer coverage for out-of-network services, usually at a higher cost-sharing rate, and tend to have higher supplemental premiums, which averaged $18 per month in 2026.

Out-of-Pocket Spending Safeguards

For 2026, the average out-of-pocket spending limit for Medicare Advantage enrollees stands at $5,421 for in-network services. When considering both in-network and out-of-network services combined, primarily applicable to PPOs, this average rises to $9,825. PPOs generally have a higher average out-of-pocket limit for in-network services ($6,592) compared to HMOs ($4,636). A key distinction from Traditional Medicare, which lacks an out-of-pocket maximum, is the regulatory requirement for all Medicare Advantage plans to cap patient expenditures.

Expanding Beyond Traditional Coverage: Supplemental Benefits

Most Medicare Advantage enrollees are in plans that furnish supplemental benefits not covered by Traditional Medicare, such as vision, hearing, and dental care. From 2025 to 2026, the availability of these particular benefits for Medicare Advantage enrollees remained consistent. However, there was a noticeable decline in the proportion of individual plan enrollees whose plans offered over-the-counter benefits, meal benefits, remote access technologies, transportation benefits, and devices for bathroom safety. For SNP enrollees, the percentage in plans offering in-home support services increased, while those with transportation benefits, bathroom safety devices, and remote access technologies saw a decrease.

Additionally, about one-third of enrollees (31%) are in plans that provide a reduction in their Medicare Part B premium, which is $202.90 per month in 2026. Most frequently, these reductions amount to less than $10 monthly. Among those in individual Medicare Advantage plans, nearly one-third (32%) received a Part B premium reduction in 2026, mirroring the figure from 2025. Of individual plan enrollees benefiting from reduced Part B premiums as a supplemental feature, 39% experienced reductions of less than $10 per month, while approximately 32% saw reductions of $100 or more per month.

The Pervasive Role of Prior Authorization

Nearly all Medicare Advantage enrollees (99%) are part of plans that mandate prior authorization for certain services, a practice rarely seen in Traditional Medicare. Prior authorization is most commonly required for high-cost services, including inpatient hospital stays (97% for acute, 93% for psychiatric), skilled nursing facility stays (95%), Part B drugs (94%), and home health services (90%). Conversely, it is infrequently required for preventive services, affecting only 6% of such cases.

Premium Dynamics: Zero-Premium Plans and Rebate Impact

As noted, 75% of Medicare Advantage enrollees in 2026 are in plans that require no premium beyond the Part B premium. In 2026, the majority (75%) of individuals enrolled in individual Medicare Advantage plans with prescription drug coverage (MA-PDs) pay only their Medicare Part B premium ($202.90). The MA-PD supplemental premium encompasses costs for both Medicare-covered Part A and Part B benefits, as well as Part D prescription drug coverage. In 2026, an impressive 96% of Medicare Advantage enrollees in individual plans open for general enrollment are in plans that offer prescription drug coverage.

When accounting for all enrollees, including those paying no supplemental premium, the enrollment-weighted average supplemental premium for 2026 is $15 per month. The portion specifically for Part D benefits averages $8 per month, a figure substantially lower than the average $36 premium for stand-alone prescription drug plans (PDPs) in 2026. This disparity in Part D premiums largely stems from MA-PD sponsors' ability to leverage rebate dollars from Medicare payments to reduce their Part D premiums. When a plan's estimated costs for Medicare-covered services (the “bid”) fall below the maximum payment allowed by the federal government in a given area (the “benchmark”), the plan retains a portion of this difference as a “rebate.” According to MedPAC, these rebates average nearly $2,400 per enrollee in 2026 for individual plans, with individual plans allocating $600, or 26%, of these rebates toward Part D benefits, including premium reductions.

For the 25% of beneficiaries (5.0 million individuals) whose plans do charge an MA-PD premium, the average monthly premium is $59, with an average of $40 attributed to the Part D component of covered benefits.

Premium Trends Over Time

Supplemental premiums paid by Medicare Advantage enrollees consistently declined between 2015 and 2025 but experienced a slight increase in 2026. The average supplemental MA-PD premiums decreased from $36 per month in 2015 to $13 per month in 2025, before rising to $15 per month in 2026. Local PPOs saw significant premium reductions, falling from $65 per month in 2015 to $15 per month in 2025, then increasing to $18 per month in 2026. Similarly, HMO supplemental premiums steadily decreased from $28 per month in 2015 to $11 per month in 2025, with a minor increase to $12 per month in 2026. Only regional PPOs, which constitute a very small and shrinking segment of enrollment, observed an increase in their plan premiums over this period, rising from $36 per month in 2015 to $75 in 2025, and further to $89 per month in 2026.

In 2026, HMOs continue to dominate, enrolling over six out of ten individual Medicare Advantage members with prescription drug coverage (61%), while local PPOs account for 38%, and regional PPOs less than 1%. The overall reduction in supplemental premiums across nearly all plans is partly attributable to the decline in premiums for local PPOs and HMOs, which have seen their enrollment share increase over this period, coupled with the growth in Medicare rebates to these plans.

Since 2015, a growing number of plans have estimated their cost of providing Medicare Part A and Part B services (the “bid”) to be below the benchmark. As plan bids have decreased, the rebate portion of plan payments has consequently risen. Additionally, because rebates are adjusted based on enrollees' health status, rebates have increased in tandem with rising risk scores. (A risk score is a metric reflecting an enrollee’s anticipated healthcare costs, based on their health status and demographic characteristics; higher scores translate to increased payments to plans.) As previously mentioned, plans are dedicating some of these rebate funds to reduce the Part D portion of the MA-PD premium. According to MedPAC, rebates for individual plans have climbed from an average of approximately $924 per enrollee in 2015 to nearly $2,400 per enrollee in 2026. This trend significantly contributes to the increased availability of zero-premium plans, thereby driving down overall average premiums.

Detailed Look at Out-of-Pocket Limits

The average out-of-pocket limit for Medicare Advantage enrollees is $5,421 for in-network services and $9,825 for both in-network and out-of-network services (for PPOs) in 2026. Federal regulations, in effect since 2011, mandate that Medicare Advantage plans establish an out-of-pocket limit for services covered under Parts A and B. In contrast, Traditional Medicare does not impose an out-of-pocket limit for covered services.

For 2026, the maximum permissible out-of-pocket limit for Medicare Advantage plans is $9,250 for in-network services and $13,900 for combined in-network and out-of-network services, though plans have the option to offer lower limits. These out-of-pocket caps apply solely to Part A and B services and do not include Part D spending, which has a distinct out-of-pocket limit of $2,100 in 2026. The size and scope of Medicare Advantage provider networks vary considerably by county and across different plans within the same county. On average, beneficiaries typically have access to about half the number of physicians available to Traditional Medicare beneficiaries in their area.

In 2026, the average out-of-pocket limit for Medicare Advantage enrollees stands at $5,421 for in-network services, encompassing both HMO and PPO participants. The average out-of-pocket limit for combined in-network and out-of-network services, which specifically applies to PPOs, is $9,825.

HMOs generally provide coverage exclusively for services rendered by in-network providers, with an average in-network out-of-pocket limit of $4,636. Enrollees in HMOs are typically responsible for 100% of the costs incurred for out-of-network care, meaning there is usually no specified limit for such services. These figures also include approximately 6 million Medicare Advantage enrollees participating in HMO Point-of-Service plans (HMO-POS), which largely function like standard HMOs but afford enrollees the option to receive certain services outside the HMO’s provider network, albeit often at a higher cost and potentially requiring prior approval.
