Understanding your health insurance policy can be a daunting task, but breaking it down into smaller parts can make it more manageable.
A coinsurance is a percentage of medical expenses that you pay after meeting your deductible. In a 75 coinsurance policy, this percentage is 75%.
You'll typically pay 75% of your medical bills after meeting your deductible, while your insurance company covers the remaining 25%.

Understanding Insurance Terms
Understanding Insurance Terms can be a daunting task, but knowing a few key concepts can make all the difference. Knowing what coinsurance is and how it works can make a huge difference in understanding how your insurance policy is used.
Coinsurance refers to the percentage of medical expenses you're responsible for paying after meeting your deductible. It's essential to review your plan's coinsurance rates and policies before enrolling to avoid surprises on your billing statement.
Carefully reviewing your insurance policy will help you plan for the future of your health and avoid unexpected costs.
What Is Coinsurance?

A coinsurance clause is a provision in an insurance policy that requires the policyholder to pay a percentage of the medical expenses. This clause is often misunderstood, but understanding its basics can help minimize confusion.
A coinsurance clause is designed to share the financial burden of medical expenses between the insurance company and the policyholder.
In the context of an insurance policy, coinsurance is a way to ensure that policyholders take an active role in managing their healthcare costs.
The video "What’s Coinsurance and How Does It Work?" explains that coinsurance, copays, and deductibles work together in an individual health care plan.
Coinsurance is typically expressed as a percentage, such as 75%, which means the policyholder is responsible for paying 75% of the medical expenses.
Calculating Costs
Calculating costs can be a daunting task, especially when dealing with complex insurance policies. To calculate your coinsurance, you'll need to convert your percentage figure into a decimal figure by moving the decimal point two spaces to the left.

For example, a 20% coinsurance rate would be 0.20 as a decimal figure. You then multiply this decimal figure by the network-approved amount for the service you had or will have. This is not the same as the amount that's billed by the medical provider, as insurance companies negotiate lower rates and require their in-network medical providers to write off the portion of their bill above that amount.
A table to help you calculate coinsurance:
For instance, if Antoine's health plan requires 20% cost-sharing and the network-negotiated price for his prescription is $150, he would owe 0.20 x $150 = $30.00 in coinsurance.
Deductible
A deductible is the initial amount you're required to pay before your insurance will help cover a portion of the costs.
This amount can be substantial, and it's essential to consider it when calculating your healthcare expenses. For example, if you have a $2,000 deductible, you're responsible for paying the full $2,000 for the year.
Certain preventive services, such as routine check-ups, vaccines, and screenings, may not be subject to a deductible.
Copay

A copay is a fixed amount you pay for specific services, such as a doctor visit.
This amount is predetermined and doesn't change based on the cost of the service. For example, you might have a $20 copay for a non-preventative doctor visit.
You pay this copay regardless of the total cost of the visit, whether it's $100 or $300.
Calculating Penalties
Calculating penalties can be a complex process, but it's essential to understand how it works to avoid unexpected costs. In some cases, penalties are applied when the value of the insured property is below the specified threshold.
A penalty is applied when the replacement amount is less than the coinsurance percentage. For example, if a policyholder has $600,000 of property insurance and a fire causes $200,000 in damages, the claim is calculated by dividing the amount of insurance purchased ($600,000) by the value at time of loss ($800,000). This factor (75 per cent) is multiplied by the amount of the loss ($200,000 x .75 = $150,000).

The formula to determine the recovery is based on the property's replacement value at the time of loss. If the value is below the specified threshold, the penalty is applied, reducing the claim payment.
Here's an example of how the penalty is applied:
In this example, if the policyholder has a 75% coinsurance percentage, they would receive $150,000 (less any deductible) for a $200,000 claim, but they would also have to pay a penalty of $50,000.
