The billing terms that decide whether behavioral-health claims get paid, defined for the operators who run a treatment program: what each one means and where it costs money.
Verification of benefits is the check you run with a payer before admission to confirm what a patient's plan covers: active coverage, deductible and out-of-pocket status, whether the level of care is a benefit, and what has to be authorized. A shallow VOB that only confirms the policy is active tells you almost nothing about whether residential days will pay.
An explanation of benefits is the statement a payer issues after processing a claim, showing what was billed, what the plan allowed, what it paid, and what falls to the patient. It is not a bill. For the billing team, EOBs are primary evidence: they carry the denial reasons and payment math you need to spot underpayments and build appeals.
An electronic remittance advice is the electronic version of the EOB: a machine-readable remittance file that lets payments post into your billing system automatically, with nothing keyed in from paper. Enrolling for ERAs with each payer speeds up posting and shows denial patterns across all of your claims at once.
Utilization review is the payer's process for deciding whether treatment is medically necessary at the level of care being provided, before, during, or after the stay. In behavioral health, residential and detox stays are reviewed on a rolling basis, and the outcome of each review determines how many days the payer will cover.
A concurrent review is utilization review conducted while the patient is still in treatment: the payer approves a set number of days, and your clinical team has to support a continued stay to get more. Days past what the payer has approved go unpaid. Ohio Medicaid, for one, pays only the first thirty days of a first or second residential admission in a calendar year when a longer stay is not approved. In residential treatment (RTC) and detox billing, each concurrent review is a point where covered days can be lost.
Prior authorization is the payer's approval, obtained before services begin, confirming it will consider the treatment for coverage. Each payer sets which levels of care need it and when: Ohio Medicaid, for example, requires it for partial hospitalization and for residential stays past thirty days on a first or second admission in a calendar year. Tufts Health RITogether lists no prior authorization or notification for intensive outpatient (IOP). Whoever runs your admissions process needs the authorization question answered before the bed is filled.
Medical necessity is the payer's standard for whether a service is clinically appropriate for the patient's condition at that level of care, judged against criteria such as the American Society of Addiction Medicine (ASAM) Criteria or the plan's own guidelines. Medical-necessity questions are answered in the clinical documentation. If the chart doesn't show why the patient needed that level of care on that day, the payer will conclude they didn't.
The UB-04 is the standard institutional claim form, used by facilities to bill payers for facility-based care. Residential, detox, and many partial hospitalization programs (PHP) bill on it, and it carries facility-specific information (bill type, revenue coding, occurrence dates) that the professional form does not. Whether your program belongs on the UB-04 or the CMS-1500 depends on your licensure and your payer contracts, and getting that wrong produces rejections in bulk.
The CMS-1500 is the standard professional claim form, used by individual clinicians and group practices to bill for professional services. Outpatient therapy, psychiatric visits, and practitioner services delivered inside a facility program can go out on it. Many treatment organizations bill both forms at once, facility charges on the UB-04 and professional charges on the CMS-1500. The two sets of charges have to stay consistent.
Per diem billing means the payer reimburses a flat daily rate that bundles everything delivered at that level of care that day, rather than paying for each service separately. Ohio Medicaid and Tufts Health Plan, for example, pay residential and detox services this way. Under a per diem, authorized days set the revenue: documentation has to support each covered day of care, and a day the payer will not authorize earns nothing.
A clean claim is one that arrives with everything the payer needs to process it: accurate patient and policy information, the authorization on file, the right form, no missing or conflicting data. Clean claims are processed on the first pass; the rest go to rework. In behavioral health, where episodes are long and the sums are large, first-pass rate is a core measure of a billing operation.
A rejection is a claim that never entered the payer's claim-processing (adjudication) system, bounced by a clearinghouse or the payer's intake for errors. A denial is a claim the payer processed and refused to pay. Rejections get corrected and resubmitted. Denials get appealed, and only denials carry appeal rights and deadlines. Rejections are the easier of the two to miss. They can sit unnoticed in a clearinghouse queue while the timely-filing deadline, the payer's cutoff for submitting a claim, approaches.
Parity refers to the Mental Health Parity and Addiction Equity Act of 2008, the federal law that generally requires health plans offering mental-health and substance-use benefits to administer them no more restrictively than comparable medical and surgical benefits. It doesn't force a plan to cover behavioral health, but where coverage exists, financial and treatment limits on it generally can't be tougher than those on the medical side. Parity comes up in appeals when a payer manages behavioral-health claims far more strictly than it manages medical and surgical claims.
A carve-out is an arrangement where a health plan hands its behavioral-health benefits to a separate company, such as a managed behavioral health organization, to administer. The payer on the patient's insurance card may not be the entity that authorizes, processes, or pays your claims. A VOB that does not identify the carve-out sends authorizations, claims, and appeals to the wrong payer. All of them have to run through the carve-out company.
Aged AR is accounts receivable that has gone unpaid past normal turnaround, tracked in aging buckets so you can see how long the money has been sitting. The older a claim gets, the less collectible it becomes, and timely-filing and appeal deadlines eventually expire. Aged AR can build from denials nobody worked, concurrent-review gaps and rejections that never resurfaced. Regular review of the aging report catches it while it can still be recovered. Working the denials in that report is part of our denial resolution and appeals support.
