ABA Billing Delays? What to Do When Payers Just Won’t Pay!

When clean claims go unpaid, authorizations stall, and payer rules shift without warning, ABA providers find themselves stuck in an endless loop of denials and delays. As the demand for ABA therapy grows, so do the complications in getting paid. Delayed reimbursements from ABA insurance billing services don’t just affect your cash flow—they threaten your ability to serve clients effectively.

Fortunately, there are clear strategies to combat this. In this article, we break down a proven, five-part approach to overcoming ABA therapy billing delays, improving revenue flow, and regaining control over your ABA billing operations with the best ABA billing software and support.

ABA Billing Red Flags: When Delays Signal Deeper Issues

Sometimes, what feels like a typical billing delay is actually a sign of a bigger problem. It’s important to know when a lag in payments crosses the line from inconvenient to alarming. For example, if clean claims are still unpaid after 30 to 45 days, or if you’re seeing multiple denials from the same payer, it’s worth investigating.

Another red flag?

When a claim is marked as accepted, but no payment arrives—and no explanation follows. Sudden changes in how EOBs are formatted or unexpected payment amounts below your contracted rates are also cause for concern. Overlooking these warning signs now can lead to much larger revenue problems later.

Subtle Delays That Signal Bigger Problems

• Clean claims aging without payment

• Repeating denials from one insurer

• Lower-than-expected payments

• No follow-up on accepted claims

• EOBs changing without notice

About 42% of ABA claim denials stem from incomplete documentation—an issue that's entirely preventable.

Common ABA Billing Mistakes That Hurt Reimbursements

Even when the issue appears to be with the payer, your internal systems might be silently contributing to the delay. Many clinics unknowingly build bad habits into their ABA billing workflow. For example, relying solely on automated ABA therapy billing software can cause errors to slip through unchecked.

If your team skips manual quality reviews before submission, small mistakes can become major obstacles. Authorizations often expire without a proper tracking system, and without reliable ABA billing specialists overseeing appeals, denied claims fall through the cracks.

 Another frequent oversight? 

Letting credentialing records go out of date. These avoidable errors not only slow things down but also cost your practice time and money.

Up to 30% of authorization denials are due to credentialing gaps, many of which lead to time-consuming peer reviews.

Why ABA Billing Gets Delayed—and How to Fix It

Sometimes, even after cleaning up your internal process, payers still drag their feet. That’s when it’s time to stop waiting and start applying pressure—strategically and professionally.

Start by submitting a formal appeal that references your state’s prompt pay laws. Get in touch with your assigned payer rep to clear up any confusion and move things forward. If you’re hitting a wall, escalate further by filing a complaint with your state’s Department of Insurance. Many payers also offer internal grievance processes—use these to your advantage. Get access to the proven email templates and escalation scripts trusted by ABA insurance billing services to cut through delays—explore the toolkit here.

Effective Escalation Tactics That Make Payers Act

• Submit detailed appeals referencing prompt pay regulations

• Contact your assigned payer rep directly

• Escalate to your state’s insurance department

• Use formal grievance procedures wisely

• Send professional emails using proven templates

One in ten claims is still denied even when correctly submitted, according to 38% of providers.

Build a Reliable ABA Billing System to Prevent Insurance Delays

While escalation can help recover delayed payments, long-term success comes from building a process that prevents problems before they happen. Strong ABA billing services not only speed up payments—they also reduce stress on your staff.

Start with an authorization tracker that alerts you before approvals expire. Monthly eligibility checks are essential since clients’ insurance can change at any time. Before sending any claim, perform a quick internal audit to catch missing codes or mismatched data. Keep an eye on denial trends—these patterns help you fine-tune documentation and billing protocols. Lastly, use a real-time dashboard to monitor claim status, spot bottlenecks, and stay ahead.

Process Fixes to Keep Claims Moving

• Track and flag upcoming authorization expirations

• Verify client eligibility every month

• Review all claims for accuracy pre-submission

• Analyze denial patterns and adjust accordingly

• Track claims in real time with dashboards to catch issues early

Using structured documentation templates cut denial-related rework by 30 minutes per 10 claims.
