The television advertisement is familiar. A recognizable face — a former athlete, a television personality — delivers the promise directly to camera: switch to Medicare Advantage and get dental, vision, hearing, fitness memberships, and transportation, often at no extra premium. The ad runs during daytime programming and local news, in the weeks surrounding the Annual Enrollment Period, targeted at the demographic most likely to be evaluating Medicare options for the first time.
The promise is not false, exactly. Medicare Advantage plans do offer extra benefits that traditional Medicare does not cover. Ninety-eight percent of individual MA plans in 2026 offer some dental coverage, some vision coverage, some hearing benefits. Traditional Medicare covers none of those. For a healthy 65-year-old evaluating coverage options, the dental allowance is real and the premium saving is real.
What is systematically misrepresented — in advertising, in broker pitches, and in plan marketing materials — is what those benefits actually deliver, how long they last, and what the enrollee has traded to receive them.
What the Extra Benefits Actually Cover
The gap between what MA advertising represents and what plans actually deliver is embedded in the structure of extra benefit design — not in outright false claims, but in the framing of benefit scope.
Dental is the primary enrollment driver and the most consequential example. Nearly all MA plans that offer dental coverage include preventive services: cleanings twice per year, examinations, and X-rays. Most also offer some level of comprehensive coverage — fillings, extractions, crowns, and in some plans, dentures and implants. The difference between preventive-only coverage and comprehensive coverage is the difference between a plan that covers a cleaning and one that covers the crown that the cleaning discovers is needed.
Annual dollar limits govern how far comprehensive dental coverage extends. A plan with a $1,000 annual dental benefit limit — a common ceiling in the MA market — covers a cleaning, an examination, and perhaps a filling. A crown costs $800 to $1,500 on average. A set of dentures costs $1,500 to $3,000. An implant costs $3,000 to $5,000. The dental allowance that the advertisement presents as comprehensive coverage may cover a fraction of the dental work an older beneficiary actually needs in a year where significant dental care is required.
Network restrictions compound the dollar limit. The dental providers included in an MA plan’s dental network are not the same as the beneficiary’s current dentist in many cases. A beneficiary whose dentist does not participate in the plan’s dental network either pays out-of-pocket or switches providers — the same network disruption documented for medical providers in Article 09, applied to dental care.
Vision coverage in MA plans typically covers one annual eye examination and a fixed benefit toward eyeglasses or contact lenses — commonly $100 to $200 per year toward frames and lenses. Eyeglasses at a retail optical chain cost $200 to $600 or more for a complete pair with prescription lenses. The vision benefit covers part of one pair, once per year, at an in-network optical provider.
Hearing benefits typically cover hearing examinations and a fixed annual allowance toward hearing aids. Hearing aids cost $1,000 to $7,000 per pair. The hearing benefit allowance may cover a low-end device or contribute toward a higher-quality one. The gap between the advertised benefit and the actual cost of hearing care for a beneficiary with significant hearing loss can be thousands of dollars.
The Enrollment Hook Function
The extra benefits are not designed to provide comprehensive supplemental coverage. They are designed to attract enrollment — specifically, the healthy enrollment that the MA program’s financial structure requires.
A beneficiary managing multiple chronic conditions and frequent specialist visits evaluates an MA plan primarily on its physician and specialist network, its prior authorization requirements, its drug formulary, and its cost-sharing structure. Those are the dimensions of coverage that affect her daily healthcare experience. The dental allowance is secondary.
A healthy 65-year-old retiring from a job that provided dental coverage evaluates an MA plan differently. The dental benefit addresses a real coverage gap at a moment when she is newly eligible for Medicare and has not yet developed the chronic conditions that will eventually make the network and prior authorization features of her MA plan consequential. The dental benefit, the zero-premium structure, and the fitness membership collectively create a package that is genuinely attractive at the point of enrollment.
MA plans design extra benefits with this population in mind. The dental benefits are broad enough to be advertised as comprehensive; the dollar limits that bound their scope are disclosed in the fine print of the plan documents rather than in the television advertisement. The fitness membership is universally available and genuinely useful to a healthy 65-year-old. The transportation benefit is advertised as a feature; what the plan documents specify about its scope and how to access it is disclosed in the evidence of coverage.
KFF research has found that while extra benefits are widely available — 98 percent of plans offer dental, vision, and hearing — data on actual utilization of supplemental benefits is not publicly available. CMS collects utilization data but does not release it to researchers or consumers. The benefit exists in the plan structure. How many enrollees actually use it, to what extent, and what they pay out-of-pocket above the plan’s contribution is not transparent to the market.
Benefit Reductions After Enrollment
The extra benefits that drive enrollment are not guaranteed to remain stable throughout the enrollment period. CMS rules allow plans to reduce or eliminate supplemental benefits from year to year, subject to notification requirements during the Annual Enrollment Period when beneficiaries can switch plans.
The pattern of benefit reduction has accelerated as insurers have faced pressure on Medicare Advantage margins. Between 2025 and 2026, the share of MA plans offering over-the-counter item allowances fell from 73 to 66 percent; the share offering meal benefits fell from 65 to 57 percent; transportation benefits fell from 30 to 24 percent. Dental, vision, and hearing benefits remained near-universal in availability, but the scope and dollar limits of those benefits have been subject to ongoing modification.
More concretely: approximately 1.8 million individual MA enrollees — roughly 9 percent of all non-SNP individual MA members as of 2024 — were required to find a new plan for 2025 because their existing plan exited the market entirely (Oliver Wyman, October 2024). [Editorial note: verify against CMS enrollment data before publication — Oliver Wyman is a credible industry analytics source but a government primary source is preferred for a figure of this specificity.] Those beneficiaries did not face a benefit reduction within their existing plan. Their plan ceased to exist. Their dental network, their physicians, their established coverage arrangements all required replacement during a single Annual Enrollment Period.
The lock-in problem compounds the benefit reduction risk. A beneficiary who enrolled in MA at 65 when she was healthy, attracted by the dental and fitness benefits, and who is now 72 and managing heart disease, faces a different calculation when her plan reduces its dental benefit. She can attempt to switch to a different MA plan with better dental benefits. Or she can return to traditional Medicare — which, as Article 11 documents, may require purchasing a Medigap supplement policy at health-status-rated premiums. The 72-year-old with heart disease may find Medigap expensive or unavailable in her state. The benefit reduction that prompted the switch consideration has revealed the lock-in that the enrollment decision created seven years earlier.
The Trade: What Enrollees Give Up
The extra benefits debate cannot be evaluated in isolation from what MA enrollees trade to receive them. The trade is documented throughout this hub but is worth stating plainly in the context of extra benefits, because the advertising presents one side of it and the fine print documents the other.
A traditional Medicare beneficiary with a Medigap supplement policy has access to any Medicare-participating physician, any Medicare-participating hospital, and any Medicare-participating specialist in the country. No prior authorization for most services. No network restriction. No annual enrollment period risk that her plan exits the market. Her Medigap policy covers the cost-sharing that traditional Medicare does not — deductibles, coinsurance, and copayments — providing comprehensive financial protection against the cost of serious illness.
What she does not have is dental, vision, or hearing coverage. She pays a Medigap premium — which varies substantially by plan type, state, age, and carrier. Plan G, the most popular Medigap plan held by 39 percent of Medigap enrollees, averaged approximately $155 per month in 2025. Across all plan types, premiums range from roughly $30 to $40 per month for high-deductible options with limited coverage to $200 or more per month for the most comprehensive plans — with wide variation by state and age (KFF, 2025). If she purchases a standalone Part D plan for prescription drugs, she pays an additional premium averaging approximately $47 per month in 2025.
An MA enrollee at zero premium (beyond the Part B premium) saves the Medigap and Part D premium costs. Against that saving, she trades: network-restricted provider access; prior authorization requirements for certain services; and the risk of the denial, network gap, and benefit reduction patterns documented in the preceding articles of this hub. The dental, vision, and hearing benefits she receives are real. The coverage she surrenders — unrestricted access to any Medicare provider, without prior authorization, without network boundaries — is also real.
Whether the trade is favorable depends on the enrollee’s current and anticipated health status. For a healthy 65-year-old, the premium savings and dental benefit may represent genuine value, and the prior authorization and network restrictions may be theoretical rather than practical constraints. For a 74-year-old managing cancer, heart failure, or stroke recovery, the restrictions are not theoretical. They are the daily operating conditions of her healthcare experience.
The enrollment advertising presents the trade as one-sided: zero premium, extra benefits, nothing lost. The fine print — the evidence of coverage, the summary of benefits, the network listing — contains the other side of the trade. The fine print is not required to appear in the television advertisement.
OIG and CMS Findings on Marketing Misrepresentation
The gap between what MA advertising represents and what plans deliver has been a recurring subject of OIG findings and CMS enforcement action.
The 2024 CMS final rule on MA marketing included new standards for television and other advertisements, explicitly prohibiting certain misleading claims about benefit scope. CMS reported that it had begun reviewing television commercials for consistency with the new rules and had rejected a substantial number as non-compliant. The volume of rejected advertisements is a measure of the prevalence of non-compliant marketing prior to the rule’s implementation — not a measure of compliance after it.
CMS enforcement capacity — the staff available to review the volume of MA advertising across television, radio, digital, and direct mail channels during and surrounding the Annual Enrollment Period — remains a practical constraint on how completely the marketing rule translates to compliant advertising in the market. OIG has found persistent gaps between what the marketing rules require and what beneficiaries encounter in the enrollment process.
The complaint record at state insurance commissioners reflects the downstream consequences: beneficiaries who enrolled based on advertised benefits and discovered, after enrollment, that the scope, network restrictions, or dollar limits made those benefits substantially less valuable than the advertising represented. The enforcement actions that result from those complaints — plan warnings, corrective action requirements, and in some cases civil monetary penalties — are documented but modest relative to the enrollment revenue that the marketing generated.
The Honest Accounting
The extra benefits that Medicare Advantage advertising promises are not fictional. Dental, vision, and hearing coverage in MA plans provide real value to the beneficiaries who use them, particularly for preventive services and moderate-cost care within the plan’s annual limits.
The honest accounting of those benefits includes what they actually cover — annual dollar limits, network restrictions, and the gap between the advertised promise and the fine-print delivery. It includes what beneficiaries trade to receive them — network-restricted access, prior authorization, and the lock-in that makes returning to traditional Medicare increasingly difficult as health status declines. And it includes the pattern of benefit reduction and plan exit that has characterized the MA market as insurer margins have come under pressure.
A beneficiary evaluating Medicare options who understands both sides of that trade is making an informed decision. A beneficiary evaluating Medicare options whose primary information source is a television advertisement during the Annual Enrollment Period is not.
The advertising is designed to produce the latter. The marketing rules and disclosure requirements CMS has developed are designed to move the balance toward the former. The distance between those two points is what the enforcement record measures.
