Deductible

A deductible is the patient’s share that comes first. HealthCare.gov defines it as the amount you pay for covered health care services before your insurance plan starts to pay, and gives the example that with a $2,000 deductible you pay the first $2,000 of covered services yourself. The plan still processes those claims: it sets the allowed amount, applies the contract, and then assigns the allowed amount to the patient instead of paying it. On the ERA that shows as a PR line with CARC 1, the deductible amount, and no payment from the plan.

Deductibles matter to billing because they move the money and the risk to the patient. A visit that would have been paid by the plan in December is owed entirely by the patient in January, when many plan years reset, and the practice has to collect it. Eligibility verification returns the deductible remaining, so the front desk can tell the patient before the visit, collect at the time of service where the practice’s policy allows, and avoid a statement cycle.

The mistake is billing a deductible without checking it. The amount the primary payer applies may already have been met at another provider the same week, in which case the plan reprocesses; the patient may have a secondary plan that covers it; or the service may be one the plan exempts from the deductible. Post exactly what the remittance says, send the secondary claim where there is one, and bill the patient for the remainder with the EOB’s own numbers.
