How We Help
Where We Take Over Your ABA Therapy Billing
Thrive manages the billing side of your ABA practice so your BCBAs and technicians can stay focused on treatment instead of chasing payers. That means matching every session to the CPT code that fits who actually delivered it, applying the HO or HM modifier correctly, and confirming protocol modification documentation supports 97155 before the claim goes out, not after it comes back denied.
Practices that choose Thrive as their ABA billing company get a team that already knows authorization unit tracking, concurrent billing rules for technician and BCBA sessions on the same date, and family training billing, instead of a generalist biller applying one code regardless of who provided the session. Whether your practice runs in a clinic, in the home, or across multiple sites, the billing rules overlap enough to share one trained team and diverge enough that generalist billers consistently get them wrong.

ABA Billing Outsourcing
From Session Billing to Payment, We Manage the Full Cycle
ABA billing runs on volume and credential precision at once, dozens of 15-minute session units billed weekly, each tied to a specific rendering provider and a specific authorization. Here is what we handle from the first eligibility check to the final payment.
Eligibility & Benefit Verification
Prior Authorization
Secures and renews authorization for assessment and treatment hours, tracking unit caps and expiration dates so sessions never run past what is approved.
Claims Submission & Scrubbing
Checks every session against the rendering provider’s credential level, modifier requirements, and authorized unit count before a claim leaves the building.
Denial Management & Appeals
Traces denials to their actual cause, whether a credential mismatch or an expired authorization, and appeals with the documentation each payer requires.
AR Follow-Up
Works open claims on a set schedule so high-volume weekly session claims do not sit past 30 days unattended.
Patient Statements & Collections
Bills families clearly for the portion insurance does not cover, including any sessions outside the current authorization.
Payment Posting & Reconciliation
Reconciles payments against the authorized rate for each code, so underpayment on BCBA-delivered sessions gets caught early.
Credentialing & Payer Enrollment
Keeps BCBAs and the practice credentialed and enrolled with the commercial and Medicaid payers your families actually carry.
Reporting
Regular reporting on claim status, denial trends, and AR aging broken out by rendering provider and code type.

What is the difference between 97153 and 97155?
CPT 97153 reports direct treatment delivered by a technician following a protocol the BCBA already designed, billed in 15 minute units. CPT 97155 reports direct treatment delivered by the BCBA or another qualified health professional who is actively modifying the protocol in real time based on the patient's response during that session. The two can sometimes be billed concurrently when the BCBA is present and modifying the protocol while the technician delivers treatment, but each provider's activity needs its own documented time and the payer's required modifier.
Why does ABA billing depend so heavily on who delivered the session?
Every core ABA CPT code is tied to a specific provider credential level. Codes like 97152, 97153, and 97154 are billed when a technician delivers the service under a BCBA's direction. Codes like 97151, 97155, 97156, 97157, and 97158 are billed only when a BCBA or other qualified health professional personally delivers the service. Billing the wrong code for the credential level of the person who actually provided the session is one of the most common and most audited ABA billing errors.
Denial Patterns
The Issues That Can Get ABA Claims Denied
These are not generic billing problems. Each one is specific to how payers adjudicate session-based, credential-tied ABA claims.
Wrong Code for Rendering Provider
Billing 97155 for a session an RBT delivered without BCBA protocol modification, or billing 97153 for BCBA-delivered work, mismatches the code to the credential level of the provider who actually delivered the service and gets denied or downcoded on review.
Vague 97155 Documentation
A note that only says the BCBA provided supervision, without describing the specific protocol change, the clinical reasoning, and the patient’s response, does not support 97155 and is a common audit failure even when the clinical work itself was appropriate.
Concurrent Billing Without Modifier Support
Billing 97153 and 97155 for the same patient on the same date requires the BCBA’s protocol modification activity to be documented separately from the technician’s direct treatment time, and claims without that distinct documentation and the correct modifier are denied.
Missing or Expired Authorization
ABA authorizations are typically issued for a fixed unit count over a defined period, and sessions delivered after the authorization expires or beyond the authorized unit cap are denied regardless of medical necessity.
Unit Rounding Without Documentation
Billing a full 15 minute unit for a session that ran short, without a documented clinical reason for the discrepancy, is treated as a billing integrity issue rather than a simple rounding choice.
Family Training Underbilling
Caregiver and family training delivered by the BCBA under 97156 is frequently left off the claim entirely, since practices bundle it into the general treatment note instead of billing it as its own service.
Category III Code Coverage Gaps
0362T and 0373T are accepted only by select payers, and billing them without first confirming that specific payer’s coverage results in an outright denial rather than a partial payment.
Session Note and Authorization Mismatch
A session billed for a program or goal that does not match what the current authorized treatment plan covers is denied even when the clinical work was medically appropriate.
Our Process
How We Fix It: Our ABA Billing Process
Every step below exists because of a specific denial pattern above. Nothing here is generic.
Eligibility & Authorization Clearance
We confirm coverage and the current authorized unit count and date range before scheduling sessions, since ABA authorizations run on fixed unit caps that reset on their own schedule.
ABA-Trained Coding Review
Every claim is coded by billers who match the CPT code to the actual rendering provider's credential level and confirm protocol modification documentation supports 97155.
Pre-Submission Modifier & Unit Scrubbing
Claims are checked for HO, HM, and HN modifier accuracy, concurrent billing support, and unit counts against the authorization before they reach a payer.
Clean Claim Submission
Corrected claims go out within 48 hours, keeping your ABA billing cycle moving instead of sitting in a queue.
Denial Root-Cause & Appeal
Any denial is traced to its actual cause, a credential mismatch, an expired authorization, or a documentation gap, and appealed with the documentation that specific payer requires.
AR Follow-Up & Reporting
Outstanding claims are worked on a set follow-up schedule until resolved, with regular reporting back on where your numbers stand.

FAQ
ABA Therapy Billing FAQs
How much does ABA Therapy medical billing cost?
Fee structures are typically based on a percentage of collections and are set after we review your weekly session volume and provider mix, since a technician-heavy practice bills very differently than one with a high proportion of BCBA-delivered sessions. You get a custom fee schedule after your Free 15-Minute Practice Revenue Review, with no obligation to sign anything.
How long does onboarding take?
Most ABA practices are fully onboarded within one to two weeks. We start with a free billing audit to see where claims are getting stuck, then align our coding and submission workflow to your current documentation process, with no disruption to your daily session schedule during the switch.
Can you take over our existing AR and open claims?
Yes. We review your open AR, including anything already aged past 30 or 60 days, and prioritize the claims most likely to be recovered first. Older assessment, direct treatment, and family training claims often still qualify for appeal well past their original denial date.
Do you bill BCBA and RBT sessions correctly
Yes. Our coders match every session to the CPT code that fits the rendering provider's credential level, apply the HO or HM modifier accordingly, and document protocol modification activity clearly enough to support 97155 whenever a BCBA actively adjusts the treatment protocol during a session.
How do you handle denied claims and appeals?
Every denial is traced back to its actual cause, a credential mismatch, an expired authorization, or a documentation gap on protocol modification, before we resubmit anything. We then file the appeal with the documentation that specific payer requires, rather than resending the same claim and hoping for a different result.
Is our patient data handled securely?
Yes. Patient data is handled under HIPAA safeguards across intake, coding, and reporting, and our billing team follows the same compliance standards regardless of practice size or claim volume.
How do we track our numbers?
You receive regular reporting covering claim status, denial trends, and AR aging, plus a direct line to your billing team any time you have a question about a specific claim. Nothing about your numbers lives in a black box you have to dig through yourself.
Do you work with ABA practices in every state?
Yes. Our team supports ABA therapy clinics, in-home providers, and multi-site ABA groups across all 50 states and works with Medicaid, Medicare Advantage, and commercial payers nationwide. Your location does not change how thoroughly we work your claims or how quickly you get paid.
