What is Coinsurance

Written by   Updated June 25, 2024

Regarding health insurance plans, it is easy to need clarification. Some terms you will hear include copay, deductible, and coinsurance, which require explanations to understand what exactly you are responsible for. For over ten years, WeCare Billing LLC has been a reliable name in Healthcare Revenue Management and billing, educating patients about their rights. Today, we’ll talk about coinsurance as one of the main factors in estimating out-of-pocket medical costs.

Coinsurance Explained:

After meeting your annual deductible, you have to pay a certain percentage of the approved charge for medical service as a patient. Allow us to expound on this:

  • Deductible: This is the fixed amount you pay yearly for medical services covered by your insurance before the company pays part.
  • Allowed amount: This is agreed upon with the health insurer as payment for a particular service; it may not concur with billings (the whole charge from a health care provider to the patient).
  • Coinsurance percentage: This will be the amount of allowable charges left for you as an individual after the deductible limit has been crossed. 20%, 30%, or 80/20 are common coinsurances (meaning that there would be eighty per cent insurance coverage and the patient responsible for twenty per cent).

Here’s an example to illustrate:

See yourself in a health insurance policy with a 20% coinsurance and $2,000 deductible. You go to the doctor for an examination that costs $500. Below is how your expenses would have been:

  • You pay the deductible first. If you still have to satisfy your deductible on this, you would be responsible for the $500 bill.
  • After meeting the deductible: If other medical bills came up throughout the year and all reached your $2,000 deductible.
  • Calculating: If you visit another physician for a service worth $1,000, they may agree with insurance to pay an allowed amount of $800 (depending on their negotiated rates). Thus, as a patient, you will be charged only 20% of the amount that was allowed by insurance companies, which is equal to $160(20% multiplied by $800).

Coinsurance vs. Deductible

Coinsurance and deductibles are expenses you pay out of your pocket in partnership with your insurer. Here’s a critical difference:

  • Deductible: This is any set amount you pay before insurance affects anything. Deductibles are usually paid annually once (except if you have separate in-network and out-of-network deductibles).
  • Coinsurance is a ratio you pay after the deductible is met. It applies only to a certain amount comprising of covered services. Depending on healthcare requirements, coinsurance costs will be incurred several times yearly.

Calculating Your Coinsurance Costs: A Step-by-Step Guide

Knowing how to compute one’s coinsurance will enable you to set out a budget for health care expenses. Here is how:

  1. Understand your plan details: Look for your plan documents or contact your insurer to know your deductible and the percentage of the coinsurance.
  2. Check your Explanation of Benefits. This coversheet, which comes after a covered service, provides information about changes, including the amount allowed.
  3. Compute your coinsurance: Multiply the allowed amount by the coinsurance percentage. For example, if $800 was allowed and your coinsurance is 20%, then 20% x $800 = $160 will be used as coinsurance cost.

Maximizing Your Health Insurance Benefits: Understanding Coinsurance

To make the most of your health insurance, follow these tips on how to understand what is coinsurance:

  • Review different options: When picking an insurer, look into their deductibles and percentages paid in coinsurance. A higher deductible often accompanies a lower percentage paid in coinsurance. On the other hand, lower deductible amounts may mean higher percentages paid by insurers as coinsurance.
  • Take preventive measures: Some plans pay for annual check-ups or screenings without asking policyholders to pay any amount towards deductibles or coinsurances. Such services help identify illnesses before they worsen, thus avoiding expensive treatments.
  • In-network versus out-of-network providers: Normally, medical practitioners on a given health care provider’s list charge less money because their charges are negotiated downwards with insurers. Therefore, using such doctors attracts reduced amounts of allowed care and sometimes minimal costs that come with coinsurance payments.

Coinsurance: A Transparent Look at Your Out-of-Pocket Healthcare Expenses

We are advocates of transparency in healthcare costs. Knowing what coinsurance means can help you:

  • Plan your finances effectively: Being aware of the amount you may have to contribute in terms of coinsurance enables you to prepare for it as part of your expenses.
  • Make decisions based on facts: Compare various medical services, considering their cost implications vis-à-vis the benefits expected from them and copayments required.
  • Stand up for yourself: Once everything is clear, you have every right to demand explanations concerning any billing matters or even bargain with doctors where need be.
