15.3 Dental, Vision, and Limited/Supplemental Health Policies
Key Takeaways
- Dental plans are low-limit and prevention-focused: annual maximums of $1,000-$2,500, low deductibles, and 100% preventive coverage; the annual maximum does not roll over.
- Dental service classes carry different coinsurance: Preventive 100%, Basic 70-80%, Major 50%, with orthodontia under a separate lifetime maximum.
- Discount dental plans are NOT insurance; members pay reduced fees directly with no claims, deductibles, or annual maximums.
- Vision plans cover routine exams plus a dollar allowance for lenses and frames; medical eye conditions go through major medical instead.
- Limited/supplemental policies (critical illness, hospital indemnity, AD&D, specified-disease) pay fixed cash regardless of other coverage and never replace comprehensive insurance.
Dental Insurance
Dental insurance is a low-limit health coverage focused on prevention. Compared with major medical, it has small annual maximums (typically $1,000 to $2,500 per person per year), low deductibles (about $25 to $100), and pays preventive care generously to head off costly problems.
Dental coverage may be sold as a standalone policy, an employer group benefit, or a rider, and unlike major medical it usually applies waiting periods - often 6 to 12 months for Basic and Major services - to discourage buying coverage only when expensive work is already needed. Preventive care is generally available immediately to encourage early visits.
Dental plans group covered services into classes, each reimbursed at a different coinsurance level:
| Class | Services | Typical plan pays |
|---|---|---|
| Class I - Preventive | Cleanings, exams, X-rays, fluoride | 100%, deductible usually waived |
| Class II - Basic | Fillings, extractions, simple root canals | 70-80% |
| Class III - Major | Crowns, bridges, dentures, implants | 50% |
| Class IV - Orthodontia | Braces, aligners, retainers | 50%, separate lifetime maximum |
Delivery models mirror medical plans: Dental PPO (discounts in network, reduced out-of-network coverage), Dental HMO/prepaid (assigned dentist, lowest premium, copays), and indemnity (any dentist, usual-and-customary reimbursement, highest premium). A discount dental plan is not insurance - members simply pay reduced fees directly to participating dentists, with no claims, deductibles, or annual maximums.
Worked Example: Dental Coinsurance and Annual Maximum
Ava's dental PPO has a $50 deductible, a $1,500 annual maximum, Basic at 80%, and Major at 50%. This year she has a $200 filling (Basic) and a $1,400 crown (Major), both in network. Preventive visits were 100% with no deductible.
- The deductible applies once: she pays the first $50.
- Filling: $200 - $50 deductible = $150 subject to 80%. Plan pays $150 x 80% = $120; Ava pays $80 (incl. deductible).
- Crown (Major, 50%): plan pays $1,400 x 50% = $700; Ava pays $700.
- Total plan payout: $120 + $700 = $820, well under the $1,500 annual maximum, so the cap is not yet reached.
Exam trap: The annual maximum does not carry over to next year. Orthodontia is capped by a separate lifetime maximum, not the annual maximum.
Vision Insurance
Vision insurance is typically a routine-care benefit, not a major-medical product. It covers periodic eye exams, plus an allowance toward lenses, frames, or contact lenses, on a defined schedule. A common structure pays a covered exam, new lenses every 12 months, and new frames every 12 to 24 months, with a fixed dollar allowance and a copay.
- Allowance model: the plan pays up to a set dollar amount (e.g., $150 toward frames); the member pays any excess.
- Medical eye conditions (cataract surgery, glaucoma treatment, eye injury) are handled by major medical, not the vision plan.
- Vision plans are frequently sold as voluntary employee benefits alongside dental.
Limited and Supplemental Health Policies
Limited benefit (also called supplemental or specified-disease) policies cover narrow events and pay fixed cash benefits directly to the insured, regardless of other coverage. The insured decides how to spend the cash. They are not substitutes for comprehensive coverage.
Common Limited/Supplemental Forms
| Policy | What it pays | Trigger |
|---|---|---|
| Critical illness | Lump-sum cash (e.g., $25,000) | Diagnosis of a covered condition: heart attack, stroke, cancer, kidney failure |
| Cancer / specified-disease (dread disease) | Scheduled cash benefits | Diagnosis and treatment of the named disease |
| Hospital indemnity | Fixed amount per day/admission | Each covered hospital confinement |
| Accident-only | Cash for injury, accidental death/dismemberment | Covered accidental injury |
| Accidental Death & Dismemberment (AD&D) | Principal sum for death; capital sum % for loss of limb/sight | Accidental death or dismemberment only |
AD&D worked example: A policy with a $100,000 principal sum pays the full $100,000 for accidental death. Loss of one hand or one eye usually pays the capital sum, often 50% = $50,000; loss of two limbs typically pays the full principal sum.
Hospital indemnity example: A plan paying $300/day for a covered stay pays $300 x 4 = $1,200 for a 4-day admission, in cash, even if other insurance also pays the hospital bill - because limited benefit plans do not coordinate with other coverage.
Ava's dental PPO has a $50 annual deductible, an $1,800 annual maximum, and pays Major services at 50%. She needs a $2,000 crown (Major) with no other claims this year and the deductible applies. How much does the plan pay?
