Coinsurance

If you’re a small business owner trying to navigate the world of health benefits, you’ve probably come across the term "coinsurance." But what does it really mean, and how does it impact your employees' healthcare costs? Understanding coinsurance is crucial for offering affordable, flexible health benefits without breaking the bank. Let’s break down what coinsurance is, how it works, and how it fits into health reimbursement arrangements like ICHRA.
What is Coinsurance?
Coinsurance is the percentage of healthcare costs that an insured person is responsible for paying after meeting their deductible. Unlike a copay, which is a fixed amount, coinsurance is calculated as a percentage of the total cost of a healthcare service.
Example: If your employee’s health plan has a 20% coinsurance rate and they receive a $1,000 medical bill after meeting their deductible, they would pay $200, and the insurance company would cover the remaining $800.
How Does Coinsurance Work?
Coinsurance kicks in after the insured person meets their deductible. Here’s a step-by-step look at how it works:
- Meet the Deductible: Employees must first pay their full deductible amount before coinsurance applies. For example, if the deductible is $1,500, they pay out-of-pocket until they reach that amount.
- Pay Coinsurance: Once the deductible is met, the employee pays a percentage of the medical bills. If the coinsurance rate is 20%, they cover 20% of the cost, and the insurer pays the rest.
- Reach the Out-of-Pocket Maximum: After reaching this limit, the insurance company pays 100% of the remaining costs for covered services for the rest of the year.
Example Scenario:
- Deductible: $1,500
- Coinsurance: 20%
- Out-of-Pocket Maximum: $6,000
- Medical Bill: $10,000
- Employee pays $1,500 to meet the deductible.
- The remaining $8,500 is split as follows:
- Employee pays 20% ($1,700)
- Insurance covers 80% ($6,800)
- Total paid by the employee: $3,200 ($1,500 + $1,700)
Coinsurance vs. Copay: What’s the Difference?
Many people confuse coinsurance with copays, but they work differently:
- Coinsurance: A percentage of the total cost of a service.
- Copay: A fixed amount paid for a specific service (e.g., $30 for a doctor visit).
Example Comparison:
- Coinsurance: 20% of a $200 specialist visit = $40
- Copay: Flat $30 for the same visit, regardless of the total cost
Coinsurance generally involves more out-of-pocket variability, while copays are predictable and consistent.
Why Coinsurance Matters for Small Businesses
For small businesses, coinsurance can influence the overall cost of providing health benefits. It impacts:
- Premium Costs: Plans with higher coinsurance often come with lower monthly premiums, which can save your business money.
- Employee Cost Sharing: Employees share a portion of healthcare expenses, promoting more cost-conscious healthcare decisions.
- Budget Predictability: Knowing the coinsurance rate helps predict potential out-of-pocket costs, making budgeting easier for both employers and employees.
Coinsurance and ICHRA: A Perfect Match
An Individual Coverage Health Reimbursement Arrangement (ICHRA) allows employers to reimburse employees for health insurance premiums and other qualified medical expenses tax-free. Here’s how coinsurance fits in:
- Flexibility: Employees can choose their own health plans with coinsurance levels that match their healthcare needs and financial situations.
- Cost Control: Employers set a fixed reimbursement amount, avoiding the unpredictability of traditional group health plans.
- Tax Advantages: Reimbursements for coinsurance payments are tax-free, benefiting both employers and employees.
Example: Your business offers $300 per month through ICHRA. An employee picks a plan with 20% coinsurance and uses the reimbursement to cover both premiums and coinsurance expenses, keeping their out-of-pocket costs manageable.
How to Choose the Right Coinsurance for Your Business
When selecting health benefits, consider the following:
- Employee Demographics: Younger, healthier employees may prefer lower premiums with higher coinsurance, while those with ongoing medical needs might favor lower coinsurance and higher premiums.
- Budget Constraints: Opting for higher coinsurance can reduce premium costs for your business.
- Competitiveness: Offering competitive benefits with reasonable coinsurance rates can help attract and retain top talent.
Pros and Cons of Coinsurance
Pros:
- Lower premiums for employers and employees
- Encourages smart healthcare spending
- Flexible with ICHRA for personalized employee choices
Cons:
- Unpredictable out-of-pocket expenses for employees
- Can be costly for major medical events
- Requires employees to understand healthcare costs better
Is Coinsurance Right for Your Small Business?
Coinsurance can be a great way to provide affordable health benefits while sharing costs with employees. It encourages smarter healthcare spending and gives employees more flexibility in choosing plans that meet their needs. However, it’s essential to balance premium savings with potential out-of-pocket costs for employees.
If you’re considering coinsurance as part of your health benefits package, combining it with an ICHRA could be the perfect solution. ICHRA allows you to control costs while giving employees the freedom to select a plan that suits their health and financial needs.

Frequently Asked Questions (FAQs) about Coinsurance:
Q: How is coinsurance different from a deductible?
A: A deductible is the amount you pay out-of-pocket before your insurance starts covering medical expenses. Coinsurance, on the other hand, is the percentage of the cost you share with your insurer after meeting your deductible. For example, with a 20% coinsurance rate, you pay 20% of the medical bill while your insurer covers the remaining 80%.
Q: Does coinsurance apply to all medical expenses?
A: No, coinsurance typically applies to covered services after you’ve met your deductible. Some preventive services, like annual check-ups, may be fully covered without coinsurance, depending on your plan.
Q: Is coinsurance the same for in-network and out-of-network care?
A: No, coinsurance rates are often lower for in-network care and higher for out-of-network services. In some cases, out-of-network services might not be covered at all, leading to higher out-of-pocket costs.
Q: Can I use an HRA or ICHRA to pay for coinsurance costs?
A: Yes, with an Individual Coverage Health Reimbursement Arrangement (ICHRA), you can reimburse employees tax-free for coinsurance payments, giving them more flexibility and reducing their out-of-pocket expenses.
Q: How does coinsurance impact my out-of-pocket maximum?
A: Coinsurance payments count toward your out-of-pocket maximum. Once this maximum is reached, your insurance will cover 100% of eligible medical expenses for the remainder of the plan year.
Q: What happens if I receive multiple medical bills in one year?
A: Each bill is subject to coinsurance after you’ve met your deductible. However, once your out-of-pocket maximum is met, you won’t pay any more coinsurance for the rest of the year.
Q: Can I negotiate coinsurance rates?
A: Coinsurance rates are set by your insurance plan and cannot be negotiated. However, choosing in-network providers and using cost-effective healthcare services can help minimize your out-of-pocket costs.
Q: Does coinsurance reset each year?
A: Yes, coinsurance resets at the start of each new plan year, along with your deductible and out-of-pocket maximum. It’s important to budget for these expenses annually.
Q: How do I explain coinsurance to my employees?
A: Use simple language and real-life examples. Explain that coinsurance is their share of medical costs after meeting the deductible. Providing examples like, “If your coinsurance is 20% and the bill is $100, you pay $20,” can help employees understand their financial responsibility.
Q: What should I consider when choosing a coinsurance rate for my small business health plan?
A: Consider your budget, employee needs, and the type of medical expenses your team is likely to encounter. Higher coinsurance rates lower premium costs but increase out-of-pocket expenses for employees, so finding a balance is key.
