Benefits Architecture: Understanding Copay Plans

Benefits Architecture: Understanding Copay Plans. Behind every medical decision, there’s a benefits plan quietly working in the background—determining what gets billed, what’s covered, and what the patient ultimately pays. Choosing the right health plan for your people can be challenging, and the best option often depends on your workforce’s healthcare needs and financial situation. While there are many plan types available, Copay Plans remain a popular choice because of their simplicity and predictability—especially during high-stress medical events.

In this edition of our Benefits Architecture series, we break down the anatomy of an emergency appendectomy under a Copay Plan—shedding light on what your employees can expect to pay and when their benefits can kick in.

Where the Copay Begins

When a patient arrives at the hospital with severe abdominal pain, care starts right away. Appendicitis is a medical emergency which requires prompt attention—nurses triage the patient, technicians run imaging tests, and doctors begin treatment. As care is delivered, every service is documented and coded, from facility fees and lab work to physician evaluations and diagnostic testing.

For those enrolled in a Copay Plan, the patient is responsible for a specific, fixed fee, usually due at the time of the emergency room visit.  After the copay is paid, the plan shifts into a coinsurance model, where the patient is responsible for a portion of the remaining costs. This is often structured—but can vary with plan and coverage type—as an 80/20 split, meaning the insurance company covers 80% of the allowed charges, and the patient pays the remaining 20%. Coinsurance may apply to services such as lab tests, imaging, and physician fees.

It’s important to note that the emergency room copay and coinsurance amounts do not count toward the patient’s deductible, as these services are covered under a separate cost-sharing structure. However, they do count toward the out-of-pocket maximum.

Do diagnostic tests count toward the deductible?

Once initial bloodwork and examinations have been completed, a CT scan is often required to confirm appendicitis. Imaging services like CT scans are not always included under the same ER cost-sharing rules and therefore could count towards the deductible. If the deductible is met, coinsurance will kick in once again.

Some patients may expect a specialist copay to count towards the radiologist’s services; however, these copays typically apply only to scheduled outpatient visits with a specialist—not to behind-the-scenes diagnostic reviews in an emergency. 

If the CT confirms appendicitis, the patient will likely undergo surgery. An appendectomy can involve significant costs: the surgeon’s fee, anesthesiologist’s fee, the operating room, recovery in the hospital, and more. With the patient’s deductible met, the patient would continue to pay for their portion of the allowed charges with coinsurance—until they reach the plan’s out-of-pocket maximum.

The patient may receive a prescription for medications post-surgery, such as antibiotics or pain relievers. With a Copay Plan, a predetermined pharmacy copay can apply. These amounts are usually fixed depending on the medication’s formulary tier—for example, $10 for generic or $30 for brand-name formulary drugs.

The costs of an emergency appendectomy can be significant, and a patient’s out-of-pocket expenses could reach several thousand dollars. However, with a Copay Plan, once the patient reaches their total cost-sharing limit—also known as the out-of-pocket maximum—the insurance company will cover 100% of the costs for all covered services for the remainder of the plan year.

Real cost breakdown.

Let’s assume the total billed charges for the appendectomy—including ER, imaging, surgery, and hospitalization—are $30,000. Here’s how the breakdown might look based on a standard plan with a $1,500 deductible, 80/20 coinsurance, a $250 emergency copay, an estimated $3,000 for services done in the ER, and a $4,000 out-of-pocket maximum:

• $250 ER copay and 20% coinsurance of charges for services done in the ER. The patient pays $250 plus $600 (20% of $3,000). The balance becomes $29,150.
• Deductible ($1,500): the patient pays the first $1,500 out of pocket. This could include charges for inpatient hospital stay, a professional and technical charge for the use of the CT scan, as well as surgical fees. Patient pays $1,500 – balance is $27,650
• Coinsurance (20% after deductible and copays): After meeting the copays and deductible, the remaining allowed amount is $27,650. The patient would pay 20% of that amount, which equals $5,530.
• Out-of-Pocket Maximum ($4,000 cap): The out-of-pocket maximum limits the patient’s total payment to $4,000. The patient would then pay $1,650 (to meet the out-of-pocket maximum), and insurance would pay the remaining $26,000.

After the appendectomy.

Several weeks later, the patient will receive an Explanation of Benefits (EOB)—a statement from the insurance carrier that outlines what was billed, what was covered, and what the patient owes. Around the same time, separate bills may arrive from the hospital, surgeon, and radiologist. For patients unfamiliar with the process, this can feel overwhelming, especially while recovering from surgery.

Even after an employee receives a Summary of Benefits and Coverage (SBC) during open enrollment—a document that outlines exactly how an employee’s plan is structured, including their specific deductible, coinsurance, and out-of-pocket maximum—they may still have questions throughout the year, which is why it’s important to discuss their benefits frequently and have a person they can reach out to if needed.

Supporting employees.

A Copay Plan may seem straightforward on paper, but when faced with an emergency, the details can quickly become confusing. By walking through real-life scenarios—like an emergency appendectomy—employees and employers can gain transparency, understand costs, and better identify opportunities to improve the plan.
