9.14 Dental Insurance

A dental insurance plan must clearly outline the benefits provided, any exclusions, and limitations on coverage. Typically, dental plans specify an annual maximum dollar benefit, rather than limiting the number of appointments or teeth treated.

Dental coverage can be offered on either an individual or group basis. Some plans restrict the choice of dentists, while others may limit the types or amounts of benefits available. Services rendered immediately before the termination of the plan are generally covered, provided they fall within the policy's terms.

Additionally, certain group health and dental plans may use an integrated deductible, meaning that expenses incurred under both plans contribute to a shared deductible amount. Understanding these provisions is essential for accurately evaluating the scope and limitations of a dental plan.

Choice of Providers

Dental coverage offers a variety of options, similar to the range of choices available in health insurance. Common types of dental plans include:

• Conventional insured plans issued by insurance companies
• Dental service plans
• Blue Cross/Blue Shield dental plans
• Managed care or prepaid dental plans

Regardless of the type of plan selected, dental insurance must provide the insured with a choice of dental providers, ensuring access to care is not restricted solely by the plan structure.

Types of Dental Care

The field of dentistry is highly specialized, with different practitioners focusing on specific areas of care. Key dental specialties include:

• Endodontics – Treatment of dental pulp and root canal procedures
• Orthodontics – Correction of teeth alignment and other dental irregularities
• Periodontics – Diagnosis and treatment of gum diseases and related conditions
• Prosthodontics – Fabrication and fitting of dentures, bridges, and other prosthetic devices
• Restorative Care – Restoration of the functional use of natural teeth through fillings, crowns, and other procedures
• Oral Surgery – Surgical management of diseases, injuries, and structural defects of the teeth, gums, and jaw

Dental benefits may be administered under a scheduled plan, a nonscheduled plan, or a combination of both, depending on the terms of the policy. Scheduled plans pay predetermined amounts for specific procedures, whereas nonscheduled plans base payment on usual and customary fees.

Scheduled (Basic) Plan: Under a scheduled plan, benefits are paid according to a predefined schedule of dental procedures. The maximum benefit for each procedure is typically set below the usual, customary, and reasonable (UCR) dental charges, meaning the insured may be responsible for amounts exceeding the schedule.

Nonscheduled (Comprehensive) Plan: In a nonscheduled plan, benefits are determined based on usual, customary, and reasonable (UCR) fees. High-cost procedures, such as dentures, are typically covered under this type of plan, with payment reflecting prevailing dental charges for the procedure.

Combination Plan: A combination plan integrates elements of both scheduled and nonscheduled coverage. Certain procedures are reimbursed according to the schedule of benefits, while others are paid based on usual, customary, and reasonable charges, providing a mix of predictable and flexible coverage.

Benefit Categories

Type of Dental Care	Characteristics
Diagnostic/Preventive	Covers routine dental examinations, cleanings, and diagnostic services such as x-rays.
Basic	Includes essential restorative procedures, such as fillings, periodontal treatments, and root canals.
Major	Encompasses more complex and costly procedures, including crowns, dentures, bridges, and orthodontic treatments.

Deductibles and Coinsurance

Dental plan deductibles typically require the insured to pay an annual amount, often ranging from $50 to $100, before benefits for covered services are payable. After the deductible is satisfied, the plan generally applies a coinsurance requirement, typically 20% to 50% of the cost for basic and major dental services.

Diagnostic and preventive services, such as routine exams, cleanings, and x-rays, are usually exempt from both the deductible and coinsurance, allowing these services to be covered in full.

Exclusions

Common exclusions in dental insurance policies typically include:

• Purely cosmetic procedures, unless required as a result of an accident
• Replacement of existing prosthetic devices
• Duplicate dentures or other prosthetic appliances
• Oral hygiene instruction or training
• Injuries arising from occupational hazards, which are covered under Workers' Compensation
• Services provided by government agencies
• Procedures that were initiated before the effective date of coverage

Limitations (Designed to Control Costs and Eliminate Unnecessary Dental Care)

In most dental plans, deductibles are waived for routine preventive services, including exams and cleanings. These services are more fully covered to encourage preventive care, reflecting a philosophy similar to that of HMOs, which emphasize preventive medicine.

Coinsurance is applied after any deductible is met. Plans typically reimburse for the least expensive treatment option; for example, if a choice exists between a gold or silver filling, the plan will pay only for the cost of the silver filling, even if gold is selected. Additionally, dental plans often impose both annual and lifetime maximum benefit limits to control coverage costs.

Predetermination of Benefits (Precertification or Prior Authorization)

While this procedure is generally optional, it provides both the patient and dentist with a clear understanding of which services will be covered before treatment begins. This advance information allows the insurer to manage the cost of care by discouraging unnecessary or overly expensive procedures. At the same time, it gives the insured the opportunity to consider more cost-effective treatment options if coverage is limited.

Employer Group Dental Expense

Adverse Selection

A key objective in underwriting group dental plans is minimizing adverse selection, which occurs when individuals with higher anticipated dental needs are more likely to enroll. To address this, policies may implement a one-year benefit reduction, often up to 50%, or temporarily exclude certain benefits for enrollees who join after the initial eligibility period.

Allowing frequent open enrollment periods can increase exposure to immediate claims and elevate the risk of adverse selection, as individuals may wait to enroll until they require dental services.

Integrated Deductibles vs. Stand-alone Plans

Group dental insurance may be offered in conjunction with medical expense coverage, often sharing a combined (integrated) deductible across both plans.

In contrast, stand-alone dental plans are issued independently of other group insurance types and require a separate deductible specific to the dental coverage.

Referral Plans

Dental referral plans are not considered insurance and generally provide limited value. These plans, which may be associated with a group or individual health insurance policy or operate independently, often require a monthly membership fee. They primarily offer consumers a directory of dentists willing to accept reduced fees for dental services.

However, common issues with these plans include listings for dentists who no longer offer discounts or are no longer practicing. Individuals without insurance can often negotiate fee reductions independently. Referral plans that are integrated into group or individual health insurance are typically more reliable, as they are more likely to include participating dental providers.

Quiz

1. Which of the following is true regarding deductibles and coinsurance in dental plans?

A. Deductibles apply to all dental services, including preventive care.

B. Coinsurance is applied after the deductible is met, and preventive care is typically exempt.

C. Coinsurance only applies to diagnostic services.

D. Deductibles and coinsurance are not used in dental plans.

Correct Answer: B

Rationale: Most dental plans waive deductibles for preventive services such as cleanings and exams. Coinsurance applies to basic and major services after the deductible is satisfied. This structure encourages preventive care while sharing costs for more extensive procedures.

2. A scheduled (basic) dental plan differs from a nonscheduled plan because:

A. It reimburses for actual expenses up to usual and customary charges.

B. It pays a predetermined amount for each covered procedure, often below usual and customary charges.

C. It covers all procedures at full cost.

D. It only covers preventive care.

Correct Answer: B

Rationale: Scheduled plans set specific benefit amounts for procedures, which may be lower than the actual dental charges. Nonscheduled (comprehensive) plans, in contrast, reimburse based on usual, customary, and reasonable fees.

3. Which of the following is typically excluded from dental insurance coverage?

A. Routine cleanings and exams

B. Replacement of existing prosthetic devices

C. Periodontal treatments

D. Endodontic procedures (root canals)

Correct Answer: B

Rationale: Exclusions commonly include cosmetic procedures, replacement of prosthetic devices, duplicate dentures, oral hygiene instruction, occupational injuries covered by Workers' Compensation, government services, and procedures begun prior to coverage.

4. What is the purpose of predetermination of benefits (precertification or prior authorization) in dental insurance?

A. To automatically approve all procedures requested by the dentist

B. To provide the patient and dentist with an estimate of covered benefits and encourage cost-effective care

C. To eliminate deductibles and coinsurance

D. To limit preventive care coverage

Correct Answer: B

Rationale: Predetermination allows both the insured and the dentist to know which procedures are covered before treatment. This helps control costs and enables the patient to consider less expensive treatment options.

5. Which statement accurately describes adverse selection in group dental plans?

A. It occurs when only low-risk individuals enroll in a plan.

B. It is minimized by limiting enrollment periods and possibly reducing benefits for late enrollees.

C. It ensures all members receive identical benefits regardless of need.

D. It only applies to stand-alone dental plans.

Correct Answer: B

Rationale: Adverse selection arises when individuals with higher anticipated dental needs are more likely to enroll. Plans address this by reducing benefits for late enrollees or temporarily excluding certain services, particularly when open enrollment periods are frequent.
