Tap each line of this sample EOB
Yours will use slightly different words, but every EOB has these same pieces. The one line that matters most is highlighted in gold.
YOUR INSURANCE COMPANY
Explanation of Benefits — this is not a bill
The provider's sticker price. Almost nobody pays this number. It's the opening ask before your plan's negotiated discount is applied. Don't panic when it's huge — it's designed to be.
The negotiated discount. Your insurance has a contract rate with in-network providers, and this is the chunk that simply vanishes. This discount is one of the biggest things insurance does for you — even before it pays a dime.
The real price. This is what the service actually costs after the discount — the number all the remaining math runs on. Billed amount minus plan discount = allowed amount.
Your "pay first" portion. If you haven't met your annual deductible yet, part of the allowed amount lands here — you pay it, and it counts toward meeting the deductible for the rest of the year.
Your sharing portion. A copay is a flat fee; coinsurance is your percentage (often 20%) of what's left after the deductible. Both count toward your out-of-pocket maximum.
What insurance sent the provider. If this is $0 on your EOB, look for a remark code (below) explaining why — that's where denials show up.
⭐ The only number to memorize. This is what you should eventually owe the provider — deductible + copay/coinsurance combined. When the provider's bill arrives, it should match this number. If the bill is higher, something's wrong — that's what Part 2 is for.
The fine print that explains everything. These little codes say why something wasn't paid — "not medically necessary," "prior authorization required," "duplicate claim." Every code is defined somewhere on the EOB (usually the back or last page). If your EOB shows $0 paid, the reason code is where the story is.

Part 2 · Your next steps
Three questions about your EOB
Answers stay on your device — nothing is typed in, nothing is sent anywhere.
1 · What does "plan paid" show?
Look for the amount your insurance actually paid the provider.
2 · Have you received the provider's actual bill yet?
The bill comes separately, from the doctor/facility — often weeks after the EOB.
3 · Does the EOB itself look right to you?
Right provider, right date, services you actually received?
