An Explanation Of Benefits Is Not A Bill

After a health claim is processed, the insurer sends a statement showing what was charged, what was allowed and what the member may owe. It is an accounting document, and it is not a request for payment.

Four numbers do the work

The billed charge is what the provider listed. The allowed amount is what the plan's contract permits for that service, and it is usually much lower.

The plan paid figure is the insurer's share of the allowed amount. What remains is the member's responsibility, split into deductible, copay and coinsurance.

The gap between billed and allowed is the network discount. For an in-network provider that gap is written off and nobody pays it.

The provider bills separately and later

The insurer's statement arrives when the claim finishes processing. The provider's invoice arrives on its own schedule, and the two documents rarely land together.

Paying a provider before the statement arrives risks paying an amount the plan later reduces. Waiting lets the two figures be compared before money moves.

Where the two disagree, the discrepancy is usually a coding difference or a claim that processed before other information reached the insurer.

Denial codes explain the reasoning

Every adjustment carries a reason code, printed in a key on the statement. The codes distinguish between a service not covered, a service needing authorization and a claim missing information.

That distinction matters because the fix differs. A missing authorization is an appeal; a missing modifier is a corrected claim the provider resubmits.

Reading the code before calling anyone shortens the call considerably, because it identifies which party has the next task.

Errors are more common than fraud

Claims move through automated systems fed by codes entered under time pressure. Transposed codes, duplicate submissions and services attributed to the wrong date all occur routinely.

Comparing the statement against what actually happened at the appointment catches most of it. A line for a service never received is the clearest signal.

Providers correct their own errors when shown them, which is faster than appealing a correctly processed claim for an incorrectly coded service.

Appeals have deadlines set by rule

If the processing is wrong, the plan's internal appeal is the first step, followed by external review by an independent entity in many cases.

Time limits apply and they are enforced. They vary by plan type and by state, and they are stated on the statement itself.

The state insurance department accepts complaints where a plan is not following its own process, and an attorney becomes relevant where an unpaid balance moves to collection. Requirements vary by state and change over time.
