How to Choose an ABA Billing Company (Without Getting Burned)

Outsourcing billing sounds like a clean solution. Hand it off, stop chasing claims, get back to clients. In theory it works. In practice, the wrong company will quietly cost you tens of thousands of dollars before you realize what’s happening.

ABA billing is not general medical billing. The payer landscape is unique. Authorizations expire in tight windows. CPT codes like 97151–97158 carry specific documentation requirements that most billers have never seen. Units-based billing means a single field error can drop an entire day of services. And funders — Medicaid, commercial payers, self-pay, regional centers — all play by different rules.

A generic RCM firm will not know that. They’ll learn on your money.

Here’s how to evaluate a billing partner before you commit.


Red Flags That Should End the Conversation

1. They bill “mental health and behavioral health.”

That phrase is a tell. Mental health billing (CPT 90xxx codes) and ABA billing (97151–97158, H-codes) share almost nothing. If a company groups them together in their pitch, their staff almost certainly doesn’t have ABA-specific training. You want someone who bills only ABA, or at minimum has a dedicated ABA division with verifiable experience.

2. They’re vague about who handles your account.

Ask: Will I have a dedicated account rep? What is their ABA-specific experience? How many other practices do they manage? Shared queues and rotating staff are fine for commodity work. ABA billing is not commodity work. Your rep needs to know your payers, your auth cycles, and your practice’s specific billing patterns.

3. Long-term lock-in contracts with penalties for early exit.

The billing industry standard for performance is a 30–60 day termination window. Anything longer — especially with a penalty clause — is a red flag. A confident billing company doesn’t need to trap you. Be especially wary of 12-month contracts with auto-renewal.

4. They promise a collection rate without seeing your data.

“We guarantee 98% collection rate” means nothing without context. Your payer mix, your documentation practices, your authorization management — all of it affects collections. A company quoting numbers before auditing your current claims history is selling, not assessing.

5. No process for authorization tracking.

Ask specifically: how do you track authorization expiration? What happens when an auth limit is hit mid-week? Who notifies the practice? If the answer is vague, you will lose revenue to expired auths. This is one of the most common — and preventable — sources of ABA billing loss.¹


Green Flags That Signal a Real Partner

1. ABA-only or ABA-primary focus.

The more of their revenue that comes from ABA, the better their institutional knowledge. Ask what percentage of their client practices are ABA. Ask how many BCBAs or practice managers they have as clients. A company whose entire team understands ABA has no choice but to stay current with payer policy changes, CPT code updates, and Medicaid waiver requirements.

2. Software-agnostic billing.

Practice management platforms in ABA include Central Reach, Catalyst, Rethink, Theralytics, AccuPoint, and others. A billing company tied to a single platform may push you toward their preferred software — or bill inefficiently if you’re on something else. Your data lives in your system. A good partner works with what you have.

3. Transparent denial management with root-cause reporting.

Claim denials are inevitable. What matters is how they’re handled. Ask for a sample denial report. Does it show denial reason codes and frequency by payer? Does it track re-submission timelines? The top ABA claim denial reasons are predictable — a strong billing partner will have a documented fix for each one.²

4. A credentialing desk or referral network.

Credentialing and billing are intertwined. If a provider re-credentials, goes out of network, or changes tax IDs, billing is immediately affected. A company with credentialing in-house — or strong coordination with a credentialing partner — will manage those transitions without revenue gaps.

5. Clear fee structure with no surprise add-ons.

Percentage of collections is the most common model, typically ranging from 4–8% for ABA. Ask explicitly: what’s included? Statement fees, patient portal fees, ERA enrollment fees, secondary billing, appeals — all of these can appear as line items in a contract that looks simple up front.


The Evaluation Checklist

Use this in vendor conversations. Document their answers.

QuestionWhat You’re Listening For
What percentage of your clients are ABA practices?Higher is better. Pure ABA is ideal.
Who will be my dedicated account rep, and what’s their ABA background?A name and a real answer. Not “our team.”
What practice management software do you work with?Should include your current system.
How do you handle expired authorizations mid-billing cycle?Should have a documented process.
What’s your average first-pass claim acceptance rate?Benchmark: 90%+ is reasonable for ABA — see ABA RCM benchmarks for full context.³
What’s your fee structure, and what’s not included?Written itemization, not a verbal summary.
What’s your contract termination policy?30–60 days, no penalty. Walk away from anything else.
Can I speak to two current ABA practice clients as references?Yes should be immediate. Hesitation is a data point.

The Real Question

The question isn’t “how much does billing cost?” The question is “how much revenue am I losing with my current setup?”

Denial rates, auth gaps, under-coded sessions, late submissions — all of it adds up. The right billing partner doesn’t cost you money. They recover it.

ABA isn’t general healthcare billing. The best billing companies treat it that way.
