When it comes to health insurance, copays and coinsurance are two terms that confuse a lot of people. They both involve out-of-pocket costs, but they work very differently—and understanding the difference could save you hundreds or even thousands on medical bills.
Let’s clear up some common myths and misconceptions about copays and coinsurance so you can make smarter financial choices when using your health insurance.
Myth #1: Copays and Coinsurance Are the Same Thing
❌ False! Copays and coinsurance are two completely different ways you pay for medical care.
✔ Copay = A fixed fee you pay upfront for certain healthcare services (e.g., $30 for a doctor’s visit).
✔ Coinsurance = A percentage of the total cost of a service you pay after your deductible is met (e.g., 20% of a hospital bill).
Example:
- If your doctor’s visit has a $25 copay, you only pay $25 at the time of the visit, no matter the full cost of the service.
- If your plan has 20% coinsurance and the total bill is $1,000, you’ll owe $200 (after you’ve met your deductible).
Myth #2: Copays Count Toward Your Deductible
❌❌ Not exactly! Many people assume that copays help chip away at their deductible—but in most cases, they don’t.
How it actually works:
✔ Until you meet your deductible, you’re responsible for 100% of medical costs (except for certain covered preventive services).
✔ Your copay doesn’t apply until after you’ve met your deductible—meaning for most major medical expenses, you’re on the hook for the full amount until that threshold is reached.
✔ Once your deductible is met, copays kick in, allowing you to pay a fixed amount per visit instead of the full cost.
Example:
- If you have a $1,500 deductible, you’ll pay full price for doctor visits, tests, and procedures until you’ve spent $1,500 out of pocket.
- After that, your copay applies—so instead of paying $200 for a visit, you might only owe a $30 copay.
Why this matters: Many people think that paying copays means they’re working toward their deductible—but if you haven’t met it yet, those payments don’t count toward it at all.
Action Tip: Check your plan details to understand when your copays apply and how much you’ll owe before your deductible is met.
Myth #3: Once You Pay Your Deductible, You Don’t Have to Pay Coinsurance
❌ False! Even after meeting your deductible, you still owe coinsurance until you reach your out-of-pocket maximum.
Breakdown:
1️⃣ Before your deductible is met: You pay 100% of your medical costs (except for services with copays).
2️⃣ After you meet your deductible: You pay coinsurance (e.g., 20%) while insurance covers the rest.
3️⃣ Once you hit your out-of-pocket maximum: Insurance covers 100% of costs for the rest of the year.
Why this matters: If you have a high deductible health plan (HDHP), you might have to pay thousands in coinsurance before your insurance fully kicks in.
Myth #4: If You Have a Copay, You Don’t Have to Worry About Other Charges
❌ Not always true. A copay only covers the office visit itself. You might still owe extra for tests, procedures, or out-of-network charges.
Example:
- You pay a $40 copay for a specialist visit.
- The doctor orders bloodwork and an X-ray.
- If your insurance requires coinsurance for lab tests and imaging, you could owe 20% or more of those costs.
Pro Tip: Always ask, “Will there be additional charges beyond my copay?” before agreeing to tests or treatments.
Myth #5: You Always Have to Pay a Copay for Every Doctor Visit
❌ False! Some types of visits don’t require a copay, depending on your plan.
When you might NOT owe a copay:
✔ Preventative care (like annual physicals & vaccines) – Often covered 100% under ACA-compliant plans.
✔ Visits to an in-network provider after meeting your out-of-pocket max – Once you’ve hit your max, insurance pays 100%.
✔ Certain telehealth visits – Some plans waive copays for virtual consultations.
Always double-check your insurance benefits! Even if a visit is covered without a copay, you might still owe coinsurance or a deductible.
Myth #6: Coinsurance Is Always a Better Deal Than Copays
❌ Not necessarily! Whether copays or coinsurance save you more money depends on your healthcare needs.
✔ If you go to the doctor frequently, low copays are better since you pay a fixed amount instead of a percentage.
✔ If you rarely need care but might have a big expense, a low-coinsurance plan might be better since it often comes with lower monthly premiums.
Pro Tip: If you have ongoing health conditions, compare total expected costs for each plan—not just the monthly premium.
Myth #7: Copays and Coinsurance Work the Same for All Services
❌ Nope! The amount you pay depends on the type of service and whether it’s in-network or out-of-network.
How costs can vary:
- Primary care visits may have a $25 copay, while specialists require a $50 copay.
- Coinsurance for surgery might be 20%, but for ER visits, it could be 30%.
- Going out-of-network? Copays and coinsurance are often higher—or not covered at all.
Pro Tip: Always check your plan’s benefits before scheduling care, especially for specialists or hospital visits.
Final Thoughts: How to Avoid Surprise Medical Bills
Understanding copays vs. coinsurance is a key step to cutting healthcare costs and avoiding nasty surprises when the bill arrives.
What to do next:
✔ Check your insurance plan to see what your copays & coinsurance rates are for different services.
✔ Ask before treatment: Always confirm whether a visit will have just a copay or additional coinsurance.
✔ Compare costs between in-network & out-of-network providers.
✔ If you’re unsure, call your insurance provider and ask for a breakdown.
