The questions providers ask us most.

Yes. We help new behavioral healthcare facilities stand up billing operations from scratch — the workflows, the payer setup, and the documentation practices that keep claims clean from day one.

Either. We can advise your in-house team and hand off a working revenue-cycle setup, or we can run the billing ourselves — whichever fits where your facility is.

Yes. We advise on payer contracting and reimbursement strategy for your market and payer mix — which payers to pursue, how your rates compare, and where there's room to negotiate for the levels of care you deliver.

Transparent reporting on the whole revenue cycle — claim status, payer performance, denial trends and reimbursement by level of care — so leadership can see what the numbers are actually doing and decide from data, not guesswork.

Just the patient's demographics and a copy of the insurance card — however you already capture them at intake.

Commercial and managed-care plans across the lines of business behavioral healthcare facilities bill. We'll confirm the specifics for your payer mix during a free review.

A missed or misread benefit at intake follows the entire episode of care. Verifying first protects revenue and gives your admissions team the certainty to say yes with confidence.

Utilization review is the process of justifying ongoing care to the payer — presenting clinical documentation that demonstrates each level of care remains medically necessary, so authorized days aren't cut short.

Yes. We support peer-to-peer reviews — preparing the clinical case and coordinating with your team so the discussion with the payer's medical reviewer is defensible.

Strong utilization review protects authorized length of stay and builds defensible documentation — which means fewer denials downstream and more of the care you deliver actually getting reimbursed.

Every claim is created and scrubbed against payer-specific behavioral healthcare rules before it goes out — so it's filed right the first time rather than bouncing back as a rejection.

We work the denial — identify the root cause, correct it, and appeal where the denial is wrong. A denial is the start of follow-up, not the end of the claim.

Yes. You get transparent reporting on every claim — what was filed, where it stands, what was paid and what's being worked — so your billing is never a black box.

We triage the denial, find the root cause, and appeal it where it's wrong. Every denial is worked to resolution — a denial is the start of follow-up, not the end of the claim.

Root-cause analysis feeds back upstream. When a denial traces to benefits, authorizations or coding, we fix the pattern in VOB, utilization management and billing so the same denial stops recurring.

Denials and appeals are tracked against each payer's filing and appeal windows so nothing lapses on a deadline — the fastest way to turn a recoverable claim into a permanent write-off.

Aged A/R is reimbursement you've earned that's been sitting unpaid — claims that have outlived their normal follow-up window, often denied, partially paid, or simply abandoned. The older a claim gets, the harder it is to collect, which is exactly why it needs dedicated attention.

Yes — that's the core of what we do here. We routinely pick up aged and denied claims a previous biller gave up on, audit them, and pursue the ones still recoverable.

Yes. Root-cause analysis on your aged claims surfaces why A/R built up in the first place — and we fix those upstream issues so the next backlog doesn't form.

Yes. Many behavioral healthcare facilities carry a mix of in- and out-of-network relationships, and out-of-network claims demand their own strategy — benefit verification, usual-and-customary expectations, and disciplined appeals. We work both, and we tell you honestly what a given payer and plan is likely to reimburse.

When a patient needs a level of care an out-of-network payer doesn't readily cover, a single-case agreement can be negotiated to authorize and reimburse that episode. We identify those opportunities during verification and pursue them where the clinical picture supports it.

Almost certainly. Working behavioral healthcare across the country means we've handled national carriers, regional Blues plans, managed-care intermediaries and government lines. During a free billing review we confirm the specifics for your exact mix.

No — and we're careful not to imply one. What we have is fluency: years of experience with how each payer runs utilization review, what documentation their reviewers expect, and how their appeal pathways work. That knowledge is what moves authorizations and claims.

Higher levels of care — detox, residential, PHP and IOP — generally require precertification and ongoing concurrent review with Aetna. Centerline manages that process end to end, from the initial authorization through each continued-stay review.

For substance-use treatment, behavioral healthcare reviews are commonly aligned to ASAM criteria, alongside the plan's own clinical policy. We prepare and present the clinical picture to the standard the reviewer expects at each level of care.

We pursue the appeal and, where available, request a peer-to-peer review so your clinician can speak directly with the payer's reviewer.

No. Centerline is an independent revenue-cycle partner and is not affiliated with or endorsed by Aetna. What we bring is experience — years of billing Aetna behavioral healthcare claims and working their utilization-review and appeal processes.

No. We're headquartered in Laguna Hills, California, but we bill for behavioral healthcare facilities across 14 states. A multi-state footprint is one reason a facility works with a dedicated billing partner rather than staffing the full revenue cycle in-house.

It can. State parity statutes, Medicaid programs, licensing categories and out-of-network dynamics all shape what's covered and how it's authorized. We account for those differences per state instead of applying one template everywhere.

Yes. For groups operating across several states, we manage the payer relationships and authorization requirements specific to each location while giving leadership one consolidated view of the revenue cycle.
