If you’ve ever waited weeks—or even months—for an insurance reimbursement, you know the frustration. The cash flow slows down, bills pile up, and your team spends more time chasing claims than focusing on clients. In ABA clinics, even small billing mistakes can snowball into major headaches. What makes it more frustrating is that most of these errors are completely preventable. Even experienced providers fall into the trap of missing small details in superbills, leading to denied claims and payment delays. It’s not just about lost revenue—it affects client trust, team morale, and your clinic’s daily rhythm. Let’s look at the five most common superbill mistakes that silently drain time and money—and how to fix them before they hurt your bottom line.
Missing or Incorrect CPT Codes (like 97153 or 97155) CPT codes are the backbone of your superbill. If they’re missing or incorrect, your claim gets rejected instantly. For example, a misplaced digit in code 97153 (behavioral therapy, each 15 minutes) or 97155 (behavioral assessment) can confuse payers about what service was provided. Impact: A single wrong CPT code can lead to weeks of delay. Denied claims sit in accounts receivable (AR) while your staff scrambles to identify the issue and resubmit. Fix: Use smart verification tools or an ABA therapy billing service that automatically checks codes before submission. These services maintain up-to-date CPT databases and reduce human errors that can slow payments.
Incomplete Client or Provider Information You’d be surprised how often providers forget to include essential details like the client’s DOB, NPI number, or address. Even missing a single field can result in rejection. Impact: Claims without complete demographic data are flagged immediately by payers. You might get a notice saying “missing required fields” and end up redoing paperwork you thought was done. Fix: Create a superbill checklist to confirm that all fields—client, provider, and session details—are filled out correctly. Some modern billing systems can auto-fill repeat information to save time and prevent manual data entry mistakes.
Incorrect Insurance Details or Policy Numbers A common and costly mistake: inputting the wrong insurance policy number or using outdated coverage information. Clients switch plans, employers update insurance networks—and without verification, your superbill becomes invalid. Impact: Your claim goes into limbo, denied for “invalid policy number.” Meanwhile, payments that should have arrived in days stretch into weeks. Fix: Before sending claims, verify coverage and policy numbers through the payer portal. If your team struggles to keep up with insurance verifications, consider outsourcing to an ABA billing service. They can handle verification, submissions, and tracking—freeing your staff to focus on therapy, not paperwork.
Not Listing Service Dates or Session Duration Clearly Dates and duration help insurers verify the frequency and scope of care. If your superbill lacks this clarity—or worse, has mismatched dates—your claim may get flagged for review. Impact: Payers often deny claims with unclear or inconsistent service details. They may think you’re overbilling or double-counting sessions, even when it’s just an innocent omission. Fix: Train your staff to always list start and end dates, total minutes, and session counts. The clearer your superbill, the smoother your payment cycle. You can also integrate this data automatically through your practice management software to eliminate manual entry errors.
Using Non-Compliant or Outdated Superbill Formats Insurance companies frequently update claim submission requirements. If your superbill template hasn’t changed in years, it might be missing fields that payers now require. Impact: An outdated superbill can trigger compliance issues, leading to claim denials or even audits. This isn’t just about form design—it’s about maintaining professional credibility. Fix: Regularly review payer guidelines or partner with billing experts who stay current with compliance updates.

Why These Mistakes Hurt More Than You Think When claims are delayed, it’s not just the balance sheet that suffers. Therapists lose momentum, administrative staff face burnout, and clients start to question your reliability. Each denial or resubmission eats into your profit margins—and it’s demoralizing to do the same work twice for one payment. But here’s the truth: none of these problems are permanent. With proper processes, tools, and the right billing support, you can transform your reimbursement cycle from chaotic to consistent.
The Smarter Way Forward Instead of trying to fix errors after they happen, invest in prevention. Tools powered by automation can flag missing fields, validate CPT codes, and catch outdated information before the superbill even leaves your system. Clinics that use these systems often see a 30–40% reduction in denials and faster reimbursement turnaround times. Even if you prefer a human touch, professional ABA billing services combine automation with expert oversight—so you get the accuracy of technology and the reassurance of human review.
Final Takeaway Accuracy and compliance in superbills aren’t just about faster payments—they’re about building financial stability and trust. When your billing is clean, clients feel confident, your team stays motivated, and your practice runs smoothly.
