What is coinsurance?
Coinsurance is the amount, usually expressed as a fixed percentage, that an insured must pay in the event of a claim after the deductible has been paid. In health insurance, a coinsurance provision is similar to a copayment provision, except that copayment requires the insured to pay a fixed amount at the time of benefit. Some property insurance policies contain coinsurance provisions.
How does coinsurance work?
One of the most common coinsurance breakdowns is the 80/20 split. Under an 80/20 coinsurance plan, the insured pays 20% of the medical costs, while the insurer pays the remaining 80%. However, these conditions only apply once the insured has reached the deductible amount provided for by the states. In addition, most health insurance policies include a coverage cap that limits the total amount the insured pays for care during a given period.
Key points to remember
- Copay plans can make it easier for policyholders to budget for their costs because it is a fixed amount.
- Coinsurance generally shares the prices with the insured at 80/20%.
- The insured must pay the deductible with coinsurance before the company covers 80% of the bill.
Suppose you purchase a health insurance policy with an 80/20 coinsurance clause, a deductible of $1,000, and a maximum of $5,000. Unfortunately, you have to undergo outpatient surgery at the beginning of the year, costing $5,500. Since you haven’t reached your deductible yet, you must pay the first $1,000 of the bill. After spending the $1,000 deductible, you are only responsible for 20% of the remaining $4,500, or $900. Your insurance company will cover 80% of the remaining balance.
Coinsurance also applies to the level of property insurance a homeowner must carry on a structure for loss coverage.
If you need another expensive procedure later in the year, your coinsurance provision kicks in immediately because you’ve already paid your annual deductible. Also, since you have already paid a total of $1,900 out of pocket during the policy term, the maximum amount you will have to pay for services for the remainder of the year is $3,100.
Once you reach the $5,000 limit, your insurance company must pay up to the maximum policy limit or the maximum benefit allowed by a given policy.
Copay versus Coinsurance
Copayment and coinsurance provisions are ways for insurance companies to spread risk among the people they insure. However, both have advantages and disadvantages for consumers. Because coinsurance policies require deductibles before the insurer bears the cost, policyholders absorb more upfront costs.
On the other hand, it is also more likely that the maximum of the costs payable by the insured will be reached earlier in the year, which means that the insurance company must bear all the costs for the rest of the year—term of the policy.
Copay plans spread the cost of care over an entire year and make it easier to predict your medical expenses. A copay plan charges the insured a fixed amount at each benefit.
The number of contributions varies depending on the type of service you receive. For example, a visit to a primary care physician may be charged $20, while an emergency room visit may be charged $100. Other services, such as preventive care and screenings, can be fully paid with no copayments. Under a copay policy, an insured will likely pay for each medical visit.
The coinsurance clause in a property insurance policy requires that a home be insured for a percentage of its total cash value or the replacement value. Typically, this percentage is 80%, but different providers may require varying coverage percentages. If a structure is not insured at this level and the owner needs to file a claim for a covered peril, the supplier may impose a coinsurance penalty on the owner.
For example, if a property has $200,000 and the insurer requires 80% coinsurance, the owner must have property insurance coverage of $160,000.
