Top 5 Insurance Challenges ABA Providers Face, And How to Overcome Them

Insurance billing for Applied Behavior Analysis (ABA) therapy is notoriously complex. Whether you’re a solo BCBA or managing a multidisciplinary clinic, the administrative demands can be overwhelming. Between extensive documentation, ever-evolving payer requirements, and constant back-and-forth with insurance companies, it’s no wonder providers often find themselves buried under paperwork and chasing down payments.

However, gaining a deeper understanding of common billing pitfalls and how to avoid them can transform how you manage your revenue cycle. Instead of reacting to denials and delays, you can proactively implement systems that lead to faster reimbursement, fewer errors, and improved cash flow.

In this post, we’ll walk through five of the most common billing issues in ABA therapy, along with actionable tips to address each one. Whether you manage billing in-house or outsource it to a trusted partner, this guide will help you navigate the nuances of ABA insurance billing with greater confidence.

1. Authorization Delays

One of the biggest sources of frustration in ABA billing is delays in authorization. Most insurance payers require prior authorization before services can begin. If you fail to submit the correct documents, miss a payer-specific form, or even make a minor clerical error, your request can be delayed, or worse, denied. This can cause significant interruptions in care. A child may be ready to begin services, the clinical team is on standby, and parents are eager to get started. However, without authorization, you’re stuck in limbo.

Why this matters:

Many payers will not retroactively approve services. If treatment begins before authorization is secured, you could be providing care that never gets reimbursed.

Tips:

• Implement a pre-service checklist that includes: payer-specific authorization request forms, diagnostic reports (e.g., autism diagnosis documentation), treatment plan with goals and recommended service hours, Functional Behavior Assessment (FBA) if required, and referrals or letters of medical necessity.

• Assign responsibility to a designated team member or billing partner to track and follow up on all authorizations. Having a documented workflow helps reduce human error and ensures consistency.

2. Denied Claims Due to Coding Errors

ABA billing codes are highly specific, and accuracy is crucial. Commonly used codes like 97151 (assessment), 97153 (1:1 direct treatment), and 97155 (supervision or modification by a BCBA) must be paired with correct modifiers and units. Even one incorrect CPT or modifier code can trigger a denial. Worse, repeat errors can lead to red flags with payers and longer processing delays.

Why this matters:

A denied claim often leads to lost revenue, extended accounts receivable timelines, and extra administrative work for reprocessing.

Tips:

• Use billing software with built-in verification tools that flag missing or incorrect codes before submission.

• Alternatively, outsource to a billing company familiar with ABA-specific billing rules and code structures. Consistent internal audits and staff training on CPT coding updates also reduce risk.

3. Changing Payer Requirements

Insurance companies regularly update their policies, coding guidelines, and documentation requirements. These changes may affect how you write treatment plans, what diagnosis codes are accepted, how hours are authorized, or how frequently progress reports must be submitted. Failing to stay updated can lead to denials, even when your clinical care remains strong.

Why this matters:

Payer rules may shift mid-year, and what worked for one client may not apply to another, even under the same insurer.

Tips:

• Subscribe to payer newsletters or bulletins that announce policy updates. Assign one team member or billing partner to review these updates quarterly.

• Schedule payer check-in calls or meetings every 6–12 months to confirm your understanding of their requirements, particularly before submitting authorizations or renewals.

4. Credentialing and Contracting Issues

Some providers mistakenly assume they are in-network with a payer, only to find out (often after claims are denied) that credentialing was incomplete or outdated. Others may miss re-credentialing deadlines, causing lapses that affect reimbursement.

Why this matters:

Credentialing issues can result in significant delays, rejections, or unpaid services. In some cases, providers may be forced to accept reduced out-of-network rates or write off charges entirely.

Tips:

• Always verify credentialing status before scheduling a client’s first visit. Keep a centralized credentialing log with expiration dates, renewal timelines, and contact information for payer representatives.

• Reverify network status every 6–12 months. Consider using credentialing management software or outsourcing this function to avoid administrative oversights.

5. Unclear Patient Responsibility

When clients or caregivers are not clearly informed about their financial responsibility, it creates confusion and can lead to missed payments, delayed collections, and frustration for families. Many practices avoid the topic of cost up front, but this often leads to tension once the first invoice arrives.

Why this matters:

Without upfront transparency, your team may spend hours chasing payments or dealing with disputes, time that could be better spent on care delivery or growth.

Tips:

• Always verify benefits before the first visit and create a cost-of-service summary outlining expected co-pays, deductibles, and out-of-pocket expenses. Share this in writing and obtain the family’s signature to confirm receipt.

• Make sure your intake team is trained to communicate clearly and compassionately about financial expectations.

Why Prevention Is Better Than Cure

While the challenges of ABA billing are real, they are not insurmountable. Most denials, delays, and revenue disruptions stem from issues that can be prevented with proactive processes, training, and the right support. From tracking authorizations and coding correctly to staying current with payer requirements and credentialing timelines, every detail matters when navigating the world of insurance billing.

For many ABA providers, partnering with a specialized billing service is the most effective way to reduce errors and maintain a healthy revenue cycle. A knowledgeable billing team understands the nuances of ABA services, knows how to work with insurance companies, and stays ahead of payer changes, so you can focus on what matters most: delivering quality care to your clients.
