Full explanation
In depth
An explanation of benefits, or EOB, is the statement an insurer sends after it processes a claim or a pretreatment estimate. It is not a bill. MetLife says that when a dentist sends a pretreatment estimate, an EOB goes to you and the dentist detailing an estimate of what the plan will cover and at what payment level, and that actual payments may vary depending on annual maximums, deductibles, plan frequency limits and other provisions at the time of payment. After a claim, an EOB shows what was billed, what the plan allowed, what it paid and what you may owe. Reading it well is a cheap way to catch errors and to see how your plan actually treated a procedure. This entry explains the parts of an EOB and what to do when it does not match your estimate.
Also called: EOB, dental EOB, explanation of benefits dental, claim statement, how to read a dental EOB.
What is on it
The parts of a typical dental EOB
| Factor | Detail |
|---|---|
| Date and provider | The date of service and the dentist who submitted the claim. Check that they match your visit. |
| Procedure and code | Each service is listed by name or code. Compare the codes with your treatment plan. |
| Amount billed | What the dentist charged. |
| Allowed amount | The fee the plan recognizes. A network dentist accepts it as payment in full, apart from your share. |
| Plan payment | What the insurer paid, after any deductible and coinsurance. |
| Your responsibility | What you may owe the dentist. It can include a deductible, coinsurance and any amount above the plan's limits. |
| Remarks | Notes such as a frequency limit reached, a waiting period or a downgrade to a cheaper material. |
An EOB is a statement of how a claim was processed. It is not a request for payment.
Two kinds
EOB for an estimate and EOB for a claim
MetLife describes both. When a dentist submits a claim form with the proposed treatment plan before treatment, the plan sends an EOB estimating what it will cover and at what payment level. MetLife adds that the actual payment may differ because of annual maximums, deductibles, frequency limits and other provisions at the time of payment. After treatment, the claim produces its own EOB. Compare the two. If the final payment differs from the estimate, ask the plan to explain the difference in writing.
Keep both statements with your treatment records.
When it looks wrong
What to do if an EOB does not match your estimate
- Compare the procedure codes with your treatment plan and the dentist's invoice
- Check the allowed amount against the fee schedule the office gave you
- Look for remarks explaining a limit, a waiting period or an alternate benefit
- Ask the dental office to review the claim for coding errors
- Call the plan for an explanation and ask for the answer in writing
- If the plan denied the claim, ask about its appeal process and deadlines
Questions people ask
Common questions
01What is an explanation of benefits?
+
A statement from your insurer that explains how it processed a claim or estimated a treatment. MetLife says it details what services it will cover and at what payment level. It is not a bill. Read it against your treatment plan and keep it with your records.
02Is an EOB a bill?
+
No. It explains how the plan processed a claim, including what it paid and what you may owe. You pay the dental office, not the insurer, for your share. If an EOB shows a balance you did not expect, check it against the dentist's statement before paying.
03Why does my EOB differ from my estimate?
+
MetLife says actual payments may vary from a pretreatment estimate depending on annual maximums, deductibles, plan frequency limits and other provisions at the time of payment. Other reasons include coding differences and claims processed in a different benefit year. Ask the plan to explain each difference.
04What is the allowed amount on an EOB?
+
It is the fee the plan recognizes for a service. A network dentist accepts it as payment in full, apart from your deductible and coinsurance. An out-of-network dentist may bill above it. See the glossary entry on the allowed amount.
05What should I do with my EOBs?
+
Keep them with your treatment records and receipts, and compare each with the dentist's statement. They help you track your annual maximum and deductible, catch errors and support an appeal if a claim is denied. Store a copy in case you change plans.
06How do I get an EOB before treatment?
+
Ask the dental office to send the plan a pretreatment estimate. MetLife says that when the dentist sends a claim form with the proposed treatment plan, an EOB comes back to you and the dentist detailing an estimate. Ask the plan how long it takes, and whether it covers each procedure code.
07Who receives the EOB?
+
Usually the patient or the plan member, and the dentist receives a corresponding statement. MetLife says an EOB will be sent to you and the dentist for a pretreatment estimate. If someone else holds the policy, they may receive it. Ask the plan how it delivers statements.
08What does 'downgrade' mean on an EOB?
+
It can mean the plan paid toward a cheaper material or procedure than the one performed, under an alternate benefit provision. You owe the difference. See the alternate benefit page, and ask the plan to explain the provision in your policy.
09What if the EOB shows a denial?
+
Read the reason. It may be a coding error, a missing document, a waiting period, an exclusion or a limit. Ask the dental office to check the claim, and ask the plan for its appeal process and deadlines. See the guide to dental claim appeals.
10Can I use an EOB to track my annual maximum?
+
Yes. Each EOB shows what the plan paid, so adding them up shows how much of the annual maximum you have used. Compare with the plan's own balance figure, since pending claims may not be counted yet. Use the annual maximum planner.
11How long should I keep dental EOBs?
+
At least as long as the treatment matters and for any tax or appeal purpose. Keeping them for several years is common. Store copies with your treatment records and receipts, especially for implants, dentures and other work that may need documentation later.
12Is an EOB the same as a pretreatment estimate?
+
Not exactly. The pretreatment estimate is the request the dentist submits before treatment, and the EOB is the insurer's response. Ask for the response in writing, and keep it. Payment is not guaranteed, because limits and eligibility can change.
