Guide 3: How Does Insurance Work?
Let’s face it - health insurance can feel like a maze of confusing terms, fine print, and mystery charges. At BillCare, we believe you deserve clarity. Whether it’s your first insurance plan or your fifteenth claim, this guide breaks it all down.
💡 What Is Health Insurance, Really?
Health insurance is a contract between you (or your employer) and an insurance company. You pay them a monthly fee, called a premium, and in return, they help pay for your medical expenses when you get sick, injured, or just need a check-up.
But—and this is important—insurance does not cover everything. The details of what’s covered (and what isn’t) depend on your insurance plan.
💵 The Money Terms You Need to Know
Understanding what you owe starts with understanding these key terms:
1. Premium
What you pay every month, just to have insurance.
Like a subscription—Netflix for your health coverage.
2. Deductible
The amount you pay out of pocket before your insurance starts paying.
Example: If your deductible is $1,500, you pay the first $1,500 of covered services yourself.
3. Co-pay
A fixed fee you pay at the time of service.
Example: $25 for a doctor’s visit or $10 for a prescription.
4. Coinsurance
A percentage you pay after meeting your deductible.
Example: Insurance pays 80%, you pay 20%.
5. Out-of-Pocket Maximum
The most you'll have to pay in a year for covered services.
After this, insurance covers 100% of allowed costs.
🧾 What Happens When You Get Care?
Here’s how it all flows behind the scenes—and where BillCare fits in.
👩⚕️ Step 1: You Visit a Doctor or Hospital
You give your insurance card at check-in. Your provider confirms what services you received and documents everything using medical codes (see our coding guide for the details).
🏦 Step 2: Your Provider Sends a Claim to the Insurance Company
They submit a claim, which is basically a detailed bill—coded, itemized, and sent electronically to your insurance company.
This is where BillCare gets involved, helping providers correctly submit claims with the right codes and formatting so nothing gets delayed or denied.
🧮 Step 3: Insurance Reviews the Claim
Your insurance plan determines:
Which services are covered
How much they’ll pay
What portion you still owe
This part is called adjudication. It’s a fancy word for “how they decide what they’ll pay.”
📬 Step 4: You Get an EOB (Explanation of Benefits)
An EOB is not a bill—it’s a summary.
It shows:
What was charged
What insurance paid
What’s left for you to pay
Why something may not be covered
BillCare Tip: Always read your EOB! It’s your key to spotting billing errors or overcharges.
💳 Step 5: You Get a Bill (If You Owe Anything)
If there's an unpaid balance, your provider sends you a bill. This could be for:
Your Co-pay
Part of your deductible
Your coinsurance
Anything insurance didn’t cover
This is the moment most patients go, “Wait—why do I owe this?”
That’s why BillCare’s billing support is here to help clarify charges, correct errors, and make the process smoother.
🤷♀️ Why Is Insurance So Complicated?
Because:
Plans vary widely by employer, provider network, and coverage tier
Each insurance company has different policies, requirements, and approval processes
Small coding errors or missing documentation can lead to claim denials
But that’s where BillCare shines. We ensure that providers use the right codes, follow payer rules, and resolve denials fast—so your claim isn’t lost in insurance limbo.
📌 Example: A Real-World Breakdown
Let’s say you twisted your ankle and went to the ER.
Here’s what could happen:
Service | Code | Insurance Notes | You Might Owe |
|---|---|---|---|
ER Visit | CPT 99284 | Covered | Copay: $100 |
X-Ray | CPT 73610 | Covered | Deductible: $150 |
Crutches | HCPCS E0114 | Partially covered | Coinsurance: 20% ($15) |
📬 Your EOB arrives showing what was covered, what was denied, and why.
