How Cube Therapy Billing Cleared 90-Day AR in 18 Days and Achieved 98.9% Clean Claims for a Growing ABA Practice

A small but fast-growing ABA therapy practice had one big dream: to help more children and families. The clinicians were skilled, families were engaged, and the demand for services was high. But behind the scenes, the business side was falling apart.

Insurance claims piled up. Payments took months to arrive. Denials kept coming back with no clear explanation. The practice owner described it simply:

“It felt like every time we took one step forward with patient care, billing pushed us two steps back.”

Instead of celebrating growth, they were worried about payroll and wondering how long they could sustain the chaos. That’s when they decided to bring in Cube Therapy Billing.

The Turning Point: What Happened When They Switched to ABA Billing Experts

Cube didn’t just offer a billing team. They introduced specialized ABA billing services designed specifically for therapy practices.

Every new client’s eligibility and benefits were verified before sessions began.

Authorizations were submitted and tracked so services never got denied unexpectedly. Coding errors were identified by auditing CPT usage like 97153, 97155, and 97156.

A dedicated denial team categorized every denial, tracked root causes, and followed up directly with insurers. The accounts receivable backlog was tackled in daily cycles, starting with the oldest and highest-value claims.

For the first time, the practice felt like billing wasn’t just being processed. It was being managed with intent.

The Breakthrough: How ABA Billing Services Delivered Real Results

This is where the real shift happened.

Clean Claim Rate Transformation

Cube created payer-specific claim scrubbing rules that caught errors before submission. For example, missing modifiers on 97155 were flagged instantly. Within weeks, the practice’s clean claim rate rose from 86 percent to 98.9 percent. Claims that once required constant rework were now paid on the first submission.

Denials Cut to 1.1%

Denials were no longer just corrected—they were studied. Cube’s denial taxonomy categorized issues into eligibility, coding, authorization, or timely filing. One key discovery was that caregiver training codes were being rejected because documentation lacked time breakdowns. By correcting templates and training staff, Cube reduced denials from nearly 10 percent to just 1.1 percent.

AR Days Reduced from 63 to 33

The aging AR backlog was attacked with a structured system. Claims older than 90 days were escalated daily, logged, and followed up on until resolved. Cube implemented a “hot claims” tracker that ensured no high-value claim went untouched for more than 48 hours. Within 18 days, the backlog was cleared. By month four, average AR days were cut nearly in half, dropping from 63 to 33.

Cash Flow Increased by 28%

With more claims being paid on the first submission, fewer denials, and faster AR turnaround, monthly cash inflow grew by nearly one-third. The owner could finally plan payroll with confidence and start preparing for future hires without fear of shortfalls.

Metric	Before	After 120 Days
Clean Claim Rate	86%	98.9%
Denial Rate	9.2%	1.1%
AR > 90 Days	Large backlog	Cleared in 18 days
Days in AR	63	33
Monthly Collections	Baseline	+28% increase

The Lesson: Why ABA Billing Services Are the Backbone of Any Therapy Practice

This practice discovered what many ABA providers eventually learn: great therapy alone doesn’t guarantee financial stability. Billing is the backbone of a practice.

By using ABA billing services from Cube Therapy Billing, the practice turned its finances around. The change didn’t come from shortcuts but from implementing proven systems: clean claims, denial prevention, aggressive AR follow-up, and compliance-first coding.

The Takeaway: How ABA Billing Can Turn Stress Into Stability

Every ABA provider deserves to spend more time with clients and less time chasing claims. This story shows how the right ABA billing partner can turn billing from a burden into a driver of growth.

Cube Therapy Billing gave this practice back its peace of mind—and its future.
