What Is Coinsurance in Dental Insurance?

Dental insurance helps manage oral healthcare costs. Understanding plan terms, like coinsurance, is important for maximizing benefits. Coinsurance is a fundamental component of how dental insurance policies share expenses with the insured individual, defining the patient’s financial contribution after initial requirements are met.

Understanding Coinsurance in Dental Insurance

Coinsurance in dental insurance represents a percentage of a dental service’s cost that the patient pays. This obligation typically begins after the patient has met their annual deductible. The dental insurance plan then covers the remaining percentage of the approved cost.

For example, if a plan has an 80%/20% coinsurance structure, the insurance company pays 80% of the covered cost, and the patient pays the remaining 20%. This percentage-based arrangement differs from fixed fees and is a common feature in many dental benefit plans.

How Coinsurance Works with Your Dental Plan

Coinsurance becomes active once your annual deductible is paid. This deductible is a set dollar amount you pay out-of-pocket for covered dental services before your insurance plan contributes to costs. Once satisfied, coinsurance percentages apply to eligible dental procedures for the remainder of the plan year.

Different dental services often have varying coinsurance percentages. Preventive care, such as routine cleanings and exams, is frequently covered at 100% by many plans, meaning no coinsurance is applied. Basic services, like fillings or simple extractions, might have coinsurance rates where the plan covers 80% and the patient pays 20%. Major services, such as crowns, bridges, or root canals, often have higher patient coinsurance, requiring the patient to pay 50% of the cost.

Consider an example: if you have a $100 deductible and a dental filling costs $300, with your plan covering 80% (20% coinsurance) after the deductible. You would first pay the $100 deductible, leaving $200 of the service cost remaining. Your coinsurance would then be 20% of $200, which is $40. In this scenario, your total out-of-pocket cost for that filling would be $140 ($100 deductible + $40 coinsurance), while your insurance would pay $160. These coinsurance payments contribute to your annual out-of-pocket maximum.

Distinguishing Coinsurance from Other Dental Costs

Distinguishing between coinsurance, deductibles, and copayments helps navigate dental insurance benefits. A deductible is a fixed dollar amount a patient pays before their dental insurance plan covers costs for non-preventive services, typically paid once per plan year.

Coinsurance is a percentage of the cost for covered dental services that the patient pays after the deductible has been met. Copayments are fixed dollar amounts paid for a covered service at the time of the visit, regardless of the total cost. Unlike coinsurance, copayments do not count toward meeting your deductible.
