14.2 Dental, Vision, and Limited Benefit Plans

Dental, vision, and limited benefit plans are supplemental coverages that sit beside major medical. The exam tests them on cost-sharing structures, benefit categories, and the sharp line between routine and medical care. Expect questions asking which plan pays and how the deductible, coinsurance, and annual maximum interact.

Dental Insurance Structure

Dental plans group services into three categories, each typically reimbursed at a different coinsurance level. The classic split is 100/80/50.

Orthodontia, when covered, usually carries a separate lifetime maximum distinct from the annual maximum and is often limited to dependent children.

Dental Cost-Sharing (Worked Example)

A plan has a $50 annual deductible, the standard 100/80/50 schedule, and a $1,500 annual maximum. In one year a member receives a $120 cleaning (preventive), a $400 filling (basic), and a $1,000 crown (major).

• Preventive: paid at 100%, no deductible → plan pays $120.
• Basic: apply $50 deductible → $400 − $50 = $350 at 80% → plan pays $280.
• Major: $1,000 at 50% → plan pays $500.
• Total plan payment = 120 + 280 + 500 = $900, well under the $1,500 maximum.

Trap: The annual maximum is the plan's ceiling, not the member's. Once benefits paid hit $1,500, the member pays 100% of further costs.

Dental plans use a UCR (usual, customary, and reasonable) schedule or a table of allowances to cap what the plan recognizes; charges above UCR are the patient's responsibility on non-network claims.

Vision Insurance

Vision plans are benefit-schedule products that cover routine eye care on a frequency basis — they do not cover medical eye disease, which belongs to major medical.

• Vision plan pays: routine exams, refractions, glasses, contact-lens allowance.
• Major medical pays: glaucoma, cataract surgery, diabetic retinopathy, eye injuries.

The classic exam distractor pairs a cataract surgery with a vision plan. Cataract surgery is medical — major medical pays, not the vision plan.

Limited Benefit Plans

Limited benefit (or "named-peril" health) plans cover a narrow scope and are not comprehensive coverage. The exam wants you to recognize that they supplement, never replace, major medical and must disclose their limited nature. Common types:

• Dental and vision (above).
• Hospital indemnity — fixed cash per day of confinement (covered in 14.3).
• Specified disease / dread disease — pays only for a named condition such as cancer (14.3).
• Vision and dental discount cards — not insurance; they negotiate discounts only and must be marketed without using the word "insurance."

Limited benefit plans typically have no coordination with major medical; they pay regardless of other coverage, which makes per-diem hospital indemnity dollars stackable on top of a comprehensive plan.

Managed Dental Plans

Like medical coverage, dental comes in managed forms the exam expects you to distinguish:

• Dental HMO (DHMO): the member picks a network dentist, pays copays, and has no annual maximum but must stay in-network.
• Dental PPO: the member may go out of network at a higher coinsurance; in-network providers accept negotiated fees.
• Indemnity (fee-for-service): the member sees any dentist; the plan pays a UCR percentage and the member absorbs the balance.

Waiting Periods and Missing-Tooth Clauses

Major-category dental services often carry a waiting period (commonly 6 to 12 months) before coverage begins, discouraging applicants from buying coverage only when they already need a crown. A missing-tooth clause excludes replacement of teeth lost before the policy's effective date.

Trap: A bridge to replace a tooth extracted before coverage started is denied under the missing-tooth clause even though the bridge itself is a covered major service.

Dental Coverage Categories and the 100/80/50 Rule

Dental plans typically tier coverage by service category, a structure the exam expects you to recognize:

• Preventive/diagnostic (cleanings, exams, x-rays) — often covered at 100% with no deductible to encourage upkeep.
• Basic (fillings, extractions, simple restorations) — commonly 80% coinsurance.
• Major (crowns, bridges, dentures) — commonly 50% coinsurance.
• Orthodontia — often a separate lifetime maximum and limited to dependent children.

Worked example: a plan has a $50 deductible and the 100/80/50 split with a $1,500 annual maximum. A $200 filling (basic) after the deductible pays 80% of $150 = $120. The annual maximum caps the plan's yearly payout — the opposite of medical, where the out-of-pocket maximum caps the insured's cost. That reversed cap is a classic dental exam trap.

Vision and Limited-Benefit Plans

Vision plans are usually benefit-schedule products: they pay a set allowance toward an annual exam, frames, lenses, or contacts, often on a fixed frequency (e.g., one exam and one pair of lenses per year). They reimburse scheduled amounts, not a percentage of charges.

Limited-benefit (named-peril) plans — including hospital indemnity, dental, vision, and dread-disease policies — pay a fixed cash amount for a defined event rather than comprehensive reimbursement. They are supplements and must not be marketed as substitutes for major medical. Managed dental plans mirror medical managed care: DHMO (capitation, network dentists) and dental PPO (negotiated discounts, out-of-network at higher cost). The exam's recurring point: these products fill narrow gaps and pay scheduled or fixed amounts, so they cannot be sold as comprehensive coverage.
