Claim Rejection
A claim or transaction could not enter or continue processing because of an error or unmet front-end requirement. A common beginner confusion: A rejection is different from a claim that was adjudicated and denied.
In-Network
A provider, facility, or service relationship recognized under a plan’s network arrangements for the relevant context. A common beginner confusion: One provider or location being in-network does not prove every related entity is in-network.
Claim Denial
A payer-processed claim or service line was not allowed or paid as expected for a stated reason. A common beginner confusion: A denial is not the same as a front-end rejection or every unpaid balance.
Out-of-Network
A provider, facility, or service relationship outside a plan’s applicable network arrangements. A common beginner confusion: Out-of-network does not always mean no coverage, and coverage does not eliminate possible responsibility.
EOB
An Explanation of Benefits showing how a payer processed a claim and assigned amounts. A common beginner confusion: An EOB is not a bill issued by the healthcare provider.
ERA
Electronic Remittance Advice: structured electronic information describing payer claim-processing results. A common beginner confusion: ERA and EOB communicate related processing information but have different formats and audiences.
Allowed Amount
The amount a payer recognizes for a service under applicable plan and contract processing. A common beginner confusion: Allowed amount is not automatically what the payer pays or what the patient owes.
Patient Responsibility
An amount assigned to the patient after applicable processing and approved account review. A common beginner confusion: An eligibility estimate or EOB display is not always the final provider statement.
Timely Filing
A payer or contract deadline for submitting a claim or related request under current rules. A common beginner confusion: Timely filing limits are not universal across payers, plans, claim types, or actions.
Appeal
A formal request for reconsideration of a payer decision using an approved process and support. A common beginner confusion: An appeal is not the correct path for every rejection, typo, or missing field.
