Original Medicare does not cover routine dental care, routine vision exams, eyeglasses, or hearing aids. That is not a gap that crept in by accident — Medicare Parts A and B were written in 1965 to cover acute hospital and medical care, and these three categories were deliberately excluded. The result is a set of ongoing costs that affect nearly every Medicare beneficiary and compound with age. This guide maps those gaps for Sioux Falls' 39,532 Medicare beneficiaries in Minnehaha County, explains what local Medicare Advantage plans may offer to fill them, and identifies what to compare before you enroll.

Every plan count, premium, and CMS star rating below comes from public federal data — the CMS PY2026 plan landscape and 2026 CMS star ratings for Minnehaha County. Health-condition figures are from CDC PLACES 2023 for Minnehaha County adults. No invented numbers.

What Original Medicare (Parts A & B) Covers — and Doesn't

Before evaluating plan extras, it helps to know precisely where the baseline ends. Most people are surprised at how narrow coverage is for dental, vision, and hearing under the two foundational Medicare parts:

The Sioux Falls Health Picture: Why These Gaps Hit Harder Here

Coverage gaps matter more when the conditions that drive dental, vision, and hearing risk are common in the local population. CDC PLACES 2023 data for Minnehaha County shows four conditions directly linked to dental and vision health risk among local adults:

The connection between these conditions and dental or vision health is direct:

• Diabetes (10%): Poor blood-sugar control impairs the body's ability to fight gum infection, accelerates periodontitis, and slows healing after dental procedures. The diabetes-and-gum-disease relationship is two-directional — each can worsen the other. On the vision side, this is also the group that qualifies for Part B's annual dilated eye exam coverage.
• High blood pressure (31.7%): Several common antihypertensive medications cause dry mouth (xerostomia), which reduces saliva's natural cavity protection and increases cavity risk over time.
• Depression (22.3%): Depression is associated with reduced self-care including dental hygiene, and some antidepressants also cause dry mouth — a compounding risk for dental health.
• Obesity (37.4%): Metabolic conditions linked to obesity, including pre-diabetes, carry elevated gum-disease risk even before a formal diabetes diagnosis is on file.

Dental: The Largest Routine Coverage Gap

Routine dental care — cleanings twice a year, X-rays, fillings as needed — is a standard ongoing expense for most adults that grows more complex with age. Under Original Medicare, none of it is covered. There is no Part A or Part B benefit for outpatient dental cleanings, fillings, crowns, bridges, partial or full dentures, root canals, gum-disease treatment, or dental implants.

The only dental care Part A touches is work performed during a medically necessary inpatient hospital stay — oral surgery tied to a jaw fracture being treated inpatient, for example. That is a real but narrow scenario that leaves the year-in, year-out cost of preventive and restorative dental care entirely unaddressed by Original Medicare.

For the 10% of Minnehaha County adults with diabetes, the stakes are higher: gum disease and blood-sugar control interact in both directions, which means letting dental health slide has downstream effects on a chronic condition they're already managing. An adequate dental benefit in a Medicare Advantage plan is, for this group, a meaningful health investment — not a convenience add-on.

Vision: Narrow Coverage, One Key Exception

Original Medicare Part B does not cover routine eye exams for glasses or contact lenses, and it does not cover glasses, contacts, or the exams to fit them — for most beneficiaries. There are exactly two vision-related benefits in Parts A and B:

1. Annual dilated eye exam for people with diabetes — Part B covers one per year for any beneficiary with a diabetes diagnosis. At 10% prevalence in Minnehaha County, this applies to a meaningful share of local Medicare beneficiaries.
2. One standard pair of frames after cataract surgery — Part B covers standard eyeglass frames (or contact lenses) following cataract surgery where an intraocular lens implant was placed. Upgraded frames above the standard allowance are the beneficiary's cost.

Outside those two scenarios, routine eye care is not covered by Original Medicare. Annual preventive exams that catch glaucoma, macular degeneration, or diabetic retinopathy early — and the glasses or contacts most people use every day — fall entirely to you unless your Medicare Advantage plan includes a routine vision benefit.

Hearing: Covered Diagnostically, Not Practically

Original Medicare takes a narrow approach to hearing care. Part B will pay for a diagnostic hearing and balance exam if your physician orders it to diagnose a medical condition or determine a treatment plan. What Part B will not cover is a hearing exam performed to fit a hearing aid — or the hearing aids themselves.

That practical gap is significant because hearing aids are the primary treatment for age-related hearing loss, and they are substantial durable medical equipment costs. Some Medicare Advantage plans in Sioux Falls may include a hearing benefit that provides an allowance toward hearing aids through an in-network provider. The structure varies: allowance amount per ear, whether it covers one or two aids, the benefit period (how often you can use it), and which hearing aid providers are in the plan's network. The Evidence of Coverage has the actual numbers; the marketing summary often highlights the benefit without specifying the limits.

The 5 Sioux Falls Standard PPOs — What to Compare

Sioux Falls has 11 Medicare Advantage plans in Minnehaha County for 2026. The 5 standard PPOs are open to anyone with Medicare and are the plans most people in the area will evaluate for dental, vision, and hearing extras:

All five standard PPOs sit at 3.5★ from CMS — according to CMS data, that's a functional plan with average stability. Two of them, Aetna Medicare Signature (PPO) and Sanford's Align ChoicePlus (PPO), carry a $0 monthly premium. For someone comparing Original Medicare (which covers no dental, vision, or hearing) against a $0-premium Advantage plan that bundles extras, the premium cost of those extras is literally zero — but the quality and scope of the benefits still need to be evaluated against your actual needs.

How Dental, Vision & Hearing Benefits Are Structured Inside a Plan

Medicare Advantage plans must cover everything Original Medicare covers, and then they may add extra benefits on top. Dental, vision, and hearing are the three most commonly added extras. When comparing the plans we offer in the Sioux Falls area, these are the dimensions that determine real-world value:

The plan's Evidence of Coverage — not the Summary of Benefits one-pager — contains the exact annual limits, copays, and network rules. For dental in particular, the distinction between preventive (cleanings, exams, basic X-rays) and comprehensive coverage (crowns, bridges, root canals, dentures, implants) is where plans diverge most. Many plans offer preventive dental; far fewer provide meaningful comprehensive dental coverage, and those that do often set a separate and lower annual cap on comprehensive procedures.

The Sanford-vs-Avera Network Question Extends to Specialists

Sioux Falls care is organized around two major competing health systems, and that fork extends beyond hospitals and primary-care physicians. If a Medicare Advantage plan's dental, vision, or hearing network ties to a particular system or preferred-provider group, your current dentist, eye doctor, and audiologist need to be confirmed in-network before you enroll.

Sanford USD Medical Center and Avera McKennan are both strong hospital-quality performers — 5★ and 4★ from CMS, respectively. Sanford backs two of the five local standard PPOs (Align ChoicePlus and Align ChoiceElite), so beneficiaries whose dentists, ophthalmologists, or audiologists practice within Sanford-affiliated facilities should check those plans' supplemental provider networks first. Aetna and Wellmark/BCBS PPOs are worth examining for Avera patients and providers.

Where the 2026 Part D Cap Fits Into This Picture

The major 2026 Medicare news — the new $2,100 Part D out-of-pocket cap — applies to covered prescription drug costs only, not to dental, vision, or hearing services. Understanding how these cost buckets are separated helps you plan accurately:

• Drug costs: Capped at $2,100 out-of-pocket per year across all plans carrying Part D. Standard Part D deductible ceiling: $615. This ceiling is genuinely new in 2026 — the first annual drug cost cap in Medicare history.
• Medical/hospital costs: Governed by the plan's annual medical out-of-pocket maximum — a separate figure from the drug cap and varying by plan.
• Dental, vision, hearing: Governed by their own benefit limits within the plan — annual maximums, copays, and network requirements that sit in a third, separate bucket from both drug and medical costs.

A Medicare Advantage plan that bundles all three benefit types gives you a single plan card — but each bucket still has its own cost rules. The $2,100 drug cap makes the drug-cost side of the ledger more predictable than in prior years, which creates more mental bandwidth to focus the comparison on dental, vision, and hearing benefit depth and fit.

What to Watch When Comparing Plans for Dental, Vision & Hearing in 2026

1. Read "preventive" vs. "comprehensive" dental benefit descriptions carefully. A plan marketed as including dental may only cover cleanings and X-rays — not fillings, crowns, or dentures. Ask for the full benefit description from the Evidence of Coverage.
2. Confirm your providers are in-network. A dental benefit only delivers value if your dentist accepts the plan. Same for your eye doctor and audiologist. In-network provider lists can be checked on each carrier's website using your specific provider's name.
3. Compare annual maximums, not just headlines. A dental benefit with a $500 annual maximum is materially different from one with a $2,000 maximum. Get the exact figure from the Evidence of Coverage, not the marketing summary.
4. Check the hearing-aid structure: per ear, per pair, per how many years. Some plans offer a per-ear allowance; others cover both aids together. The benefit period — how frequently it resets — varies and determines how useful the benefit is in practice.
5. Layer the $2,100 Part D drug cap into your total cost model. With drug exposure now capped at $2,100, you have a cleaner picture of the total annual cost of a plan — and can make a more direct comparison of what each plan's dental, vision, and hearing extras are worth in your situation.
