You do not pay an EOB. It explains the claim. The provider sends a bill separately, and payments you already made may reduce the balance due.
Read a sample, one line at a time.
Illustrative only. This is a simplified example for covered, in-network care—not a real claim, carrier document, or coverage guarantee.
Sample health plan
Explanation of BenefitsThe amount submitted by the provider.
The contractual reduction in this example. It is not added to your share.
The amount used here to calculate the covered claim payment.
The plan’s share after the deductible and coinsurance calculation.
Your deductible and coinsurance in this example, before payments already made.
Already paid $30 to the provider? If all payments and adjustments have posted, the remaining bill for this example would be $150—not another $180.
Where the $180 comes from
- Start with the $600 allowed amount.
- Apply the remaining deductible: $75. That leaves $525.
- Your 20% coinsurance on $525 is $105.
- Your share is $75 + $105 = $180. The plan pays the other $420.
Compare the bill with the claim.
- Match the visit. Check the patient, provider, date, and services. A bill can combine more than one claim.
- Read the explanation codes. Look for adjustments, pending items, or a denial. A code explains why the plan handled a charge that way.
- Account for earlier payments. Compare the bill with your receipts and the latest EOB. Ask whether a corrected claim or another insurer is still processing.
- Ask about a mismatch. The plan can explain its claim decision; the provider’s billing office can explain the bill and payments received. Ask about due dates while a discrepancy is reviewed.
Keep a record of the answer.
Save the EOB, itemized bill, receipts, and notes from your calls. If the plan denies a service, check the notice for appeal instructions and deadlines.
