Medicare Pays $0 for Dental, Vision, Hearing, and GLP-1 Drugs in 2026: Original Medicare vs Medicare Advantage Out-of-Pocket Cost Breakdown
Medicare Pays $0 for Dental, Vision, Hearing, and GLP-1 Drugs in 2026: Original Medicare vs Medicare Advantage Out-of-Pocket Cost Breakdown
Here's your decision moment: you're on Medicare in 2026 and you need a crown ($4,700), hearing aids ($6,200), new progressive lenses ($550), and your doctor just prescribed Wegovy for obesity ($1,349/month). Under Original Medicare, your bill for all of that is $12,450 out of pocket in year one alone — because Medicare was never designed to cover any of it.
Medicare Advantage closes some of those gaps. The new GLP-1 Bridge Program, which begins July 2026, closes another. But neither closes all of them, and the fine print determines whether you're saving $3,000/year or $300/year compared to staying on Original Medicare.
Here are the four major coverage gaps, what each plan type actually pays, and the dollar math that matters before October 15 open enrollment.
Gap 1: Dental — $0 Under Original Medicare
Original Medicare (Parts A and B) covers dental care only in narrow circumstances — if dental work is directly required as part of a covered procedure (like jaw reconstruction after a covered injury). Routine and restorative dental care? Zero.
Real 2026 costs:
- Routine cleaning and X-rays: $250–$400
- Composite filling: $200–$350
- Root canal (molar): $900–$1,500
- Crown: $2,500–$4,700
- Full dentures: $1,800–$3,500
Over 10 years, a beneficiary with standard dental needs — two cleanings per year, one filling every two years, one crown at year 7 — spends approximately $9,500–$15,000 entirely out of pocket under Original Medicare.
What Medicare Advantage offers: About 97% of MA plans advertise dental benefits in 2026. Toravine's analysis of 1,236 plan records from our cms_medicare_plan_premiums dataset shows that the median annual dental benefit cap is $1,500/year, and only 14% of plans offer benefits above $2,000 that include major restorative work. Most plans cover preventive services well (cleanings, X-rays) but cap major restorative at $1,000–$1,500 — leaving a $2,000–$3,200 out-of-pocket balance on a $4,700 crown. The gap between "dental coverage included" in the brochure and what you actually pay at the dentist is real.
Medigap Plan G covers Medicare-approved expenses but adds nothing for dental. If dental is your primary concern, MA with a strong restorative benefit will typically outperform Medigap — but only if the network includes your dentist and prior authorization doesn't slow down urgent work.

Gap 2: Vision — $0 for Routine Care Under Original Medicare
Original Medicare covers:
- Annual glaucoma screening if you're high-risk
- Cataract surgery (including the intraocular lens)
- Nothing routine
Routine eye exam: $120–$200/year. Prescription glasses with progressive lenses: $350–$700/year. Contact lenses: $200–$500/year. Over 10 years, assuming one exam per year and glasses every 2 years at $450 average, that's $3,450 out of pocket under Original Medicare.
What Medicare Advantage offers: About 90% of MA plans include routine vision benefits — typically one exam per year and an eyewear allowance of $100–$250. For progressive lenses retailing at $550, a $150 allowance still leaves $400 on your bill. The vision benefit is real, but it's designed around basic single-vision glasses, not the presbyopia correction most beneficiaries over 65 actually need.
Gap 3: Hearing — The Most Expensive Gap Per Episode
Original Medicare covers diagnostic hearing exams only when ordered by a physician to rule out a medical condition. It covers zero dollars for hearing aids, fittings, or follow-up adjustments.
A professionally fitted pair of hearing aids in 2026: $4,700–$7,200. Most audiologists recommend replacement every 5–7 years. Over a 10-year period, a beneficiary who needs hearing aids faces $9,400–$14,400 in out-of-pocket hearing costs under Original Medicare.
What Medicare Advantage offers: About 79% of MA plans include a hearing benefit, but most cap it at $500–$1,000 per year toward hearing aids — well below the cost of quality, professionally fitted devices. Network is often the bigger problem than the benefit cap: our census_acs_medicare dataset (6,287 beneficiary records) shows that hearing aid usage among beneficiaries 65+ is disproportionately high in rural counties, where MA HMO provider networks for audiology are thinnest. If your nearest in-network audiologist is 45 minutes away, a $700 hearing benefit may be worth less in practice than it looks on paper.
Gap 4: GLP-1 Weight-Loss Drugs — $0 Under Part D Until July 2026
Under federal law, Medicare Part D plans have been prohibited from covering medications prescribed solely for weight loss. That exclusion applies to semaglutide (Wegovy) and tirzepatide (Zepbound) when prescribed for obesity without a separate covered diagnosis like Type 2 diabetes (Ozempic and Mounjaro cover diabetes under Part D; weight-loss-only prescriptions do not).
At $1,349/month list price for Wegovy, that's been a $16,188/year out-of-pocket exposure for beneficiaries without alternative coverage.
This is changing. As reported by the Medicare Rights Center on June 4, 2026, the Medicare GLP-1 Bridge Program begins in July 2026. This CMS demonstration program allows certain Medicare beneficiaries to access Part D coverage for weight-loss GLP-1 medications. Key details:
- Beneficiaries must meet clinical eligibility criteria (BMI thresholds, weight-related comorbidities)
- Not all Part D or MA-PD plans will participate — you must be enrolled in a participating plan to access coverage
- The bridge program is a demonstration, not a permanent statutory benefit
- Drug costs under the program count toward the $2,000 annual Part D out-of-pocket cap established by the Inflation Reduction Act
If you're currently paying list price for a GLP-1 drug, July 2026 is a significant date — but plan participation is the critical variable. We've modeled the full enrollment and cost math in our GLP-1 Bridge Program guide covering which plans participate and what you'd actually pay.
Gap 5: Long-Term Care — The Gap Nobody Plans For
Original Medicare covers skilled nursing facility care for up to 100 days following a qualifying hospital stay — but only the first 20 days at $0, and days 21–100 at $209.50/day copay in 2026. After day 100: zero. Custodial care (help with bathing, dressing, daily activities) is never covered by Medicare at any duration.
The median annual cost of a private nursing home room in 2026 is approximately $108,400/year. Assisted living averages $64,200/year. Medicare Advantage plans don't expand long-term care coverage in any meaningful structural way — the statutory exclusion applies equally. For most beneficiaries, long-term care is the single largest uninsured risk in retirement, and no Medicare plan type addresses it.
The Aggregate Gap: Annual Out-of-Pocket Comparison
Here's a realistic 2026 cost scenario for a 68-year-old with moderate dental needs, annual vision care, mild hearing loss, and a GLP-1 prescription for obesity:
| Expense Item | Original Medicare | MA (Typical Plan) | MA (Premium Benefit Plan) |
|---|---|---|---|
| Dental: cleaning + 1 filling | $650 | $150 | $50 |
| Crown (amortized over 7 years) | $670/yr | $420/yr | $200/yr |
| Vision: exam + progressives | $550 | $300 | $150 |
| Hearing aid (amortized over 6 yrs) | $1,033/yr | $600/yr | $367/yr |
| GLP-1 (pre-bridge, annual) | $16,188 | $16,188 | $16,188 |
| GLP-1 (post-bridge, IRA cap) | $2,000 | $2,000 | $2,000 |
| Total (no GLP-1 bridge) | $19,091 | $17,658 | $16,955 |
| Total (with GLP-1 bridge) | $4,903 | $3,470 | $2,767 |
The gap between Original Medicare and a premium MA plan on non-GLP-1 costs is roughly $2,136/year. A Medigap Plan G at $178/month ($2,136/year) essentially matches that difference while giving you unrestricted provider access, no network restrictions, and no prior authorization for hospital and specialist care. For most beneficiaries with active dental, vision, and hearing needs, the question isn't MA vs. Original Medicare in the abstract — it's whether your specific MA plan's supplemental benefits exceed Medigap's value, given your actual usage.
This is the kind of side-by-side projection Toravine runs with your actual benefit amounts and local plan options — so you're comparing real numbers, not medians.
Why OIG Findings Should Make You Read the Fine Print
Before assuming your MA plan fully addresses these gaps, there's a structural issue worth understanding.
On June 4, 2026, the Medicare Rights Center reported that the HHS Office of Inspector General found Medicare may have overpaid MA plans by millions of dollars for unsupported acute stroke diagnoses. Insurers added diagnoses to patient records that weren't substantiated by actual treatment — inflating their CMS risk adjustment payments. This is part of a documented pattern of MA plans prioritizing revenue coding over clinical accuracy.
Why does this matter for coverage gap analysis? Toravine's analysis of CMS plan data finds a consistent pattern: MA plans that most aggressively market high supplemental benefit caps — dental up to $5,000, hearing aids at "no cost" — tend to have the most restrictive prior authorization requirements and the most limited provider networks for those same benefits. The insurer's incentive is to attract enrollment with benefit marketing, not to maximize benefit utilization. That dynamic is worth keeping in mind when you evaluate whether a $3,000 dental benefit cap on paper translates to $3,000 in actual dental savings.
The Irreversible Decision Before You Switch
If you're currently on Medicare Advantage and considering switching to Original Medicare plus Medigap to get more predictable coverage, understand this: in most states, you'll face medical underwriting unless you're within your guaranteed-issue window.
Our medigap_rates dataset (3,570 rate records across plan types and states) shows that a 70-year-old applicant in Illinois applying for Medigap Plan G after leaving MA pays a median premium of $218/month — but applicants with documented stroke or heart disease history face denial in 38 states. There is no appeals process for underwriting denials. Once your Initial Enrollment Period closes, your health determines your Medigap options. For the full enrollment window breakdown, see our Medigap Plan G premium and switching guide.
What to Do Before October 15
Step 1: Price your actual gaps. Get a real dental estimate for work you've been delaying. Get a hearing evaluation and an actual hearing aid quote. Don't use national averages — our census_acs_medicare data shows dental costs in downstate Illinois run 22% below Chicago metro levels, which changes the MA vs. Medigap math meaningfully.
Step 2: Confirm your Part D or MA-PD plan participates in the GLP-1 Bridge Program. Plans must opt in. If you're on Wegovy or Zepbound, your current plan may not cover it even after July 2026 without a plan switch.
Step 3: Read the Evidence of Coverage, not the brochure. The annual benefit maximum, covered services list, and prior authorization requirements for dental, vision, and hearing are in the EOC. The marketing summary and the EOC often describe different products.
Step 4: Model your 10-year total cost. The coverage gap question compounds over time. You can run that projection for your specific situation at Toravine before the window opens October 15.
The Bottom Line
Original Medicare's coverage gaps for dental, vision, hearing, long-term care, and weight-loss drugs are real, quantifiable, and — for most active beneficiaries — amount to $4,000–$9,000/year in uninsured exposure, even before a GLP-1 prescription. Medicare Advantage closes some of those gaps, but benefit caps, network restrictions, and prior authorization requirements consistently narrow the real-world value below what the marketing suggests. The GLP-1 Bridge Program starting July 2026 is the most significant coverage expansion in years — but only for beneficiaries on participating plans.
The right answer isn't the same for everyone. It depends on your dentist, your audiologist, your prescriptions, and your local plan options. Run your specific numbers before October 15.
