ASP-RCM Case Study. From 35% denials to single digits in two billing cycles.

A single-owner BCBA was doing billing at 9pm after sessions. The denial rate had crept past 35%. She tried two billing services and a software platform; nothing held. Two ASP-RCM billing cycles later, denials were below 8%, and she had her evenings back.

"I'm a clinician. I want to be a clinician. I do not want to be a billing department." That was the first sentence of the discovery call. By the end of the conversation, the actual problem was visible: not workload, not technology, workflow. Solo BCBAs need a billing partner who treats their practice like the seven-figure operation it is, not the side project it looks like from the outside.

01 / Starting pointThe reality

The owner was billing herself, between sessions and after hours. The previous billing service had moved her to a "self-service portal" that effectively handed back all of the work she had outsourced. The denial rate sat at 35% and she had no visibility into why.

Three immediate findings:

  • Texas Medicaid HIPP enrollment was lapsed for 4 of 14 clients, the source of roughly 40% of denials
  • Session-note templates didn't reference treatment-plan goals, driving medical-necessity denials on commercial claims
  • Time-in/time-out wasn't documented to the minute, creating a recoupment exposure

02 / The fixWhat changed in two cycles

Move 01

Eligibility cleanup

Texas Medicaid HIPP re-enrollment for affected clients. Eligibility-driven denials cleared in one cycle.

Move 02

Note template rebuild

Goal-referenced template with required fields. Locked in EMR.

Move 03

Time validation

Minute-level time-in/time-out enforced at note close. Recoupment exposure eliminated.

Move 04

Direct/indirect mapping

Code-by-code map for solo-BCBA workflow. 97155, 97156, 97151 used correctly.

Move 05

Weekly check-in

20-minute Friday call with senior partner. KPIs in writing, action items tracked.

Move 06

End-to-end ownership

ASP-RCM owns submission, posting, denial work, and follow-up. She does clinical.

I got my Tuesdays back. That sounds like a small thing. After three years of billing at 9pm, it's not a small thing.

04 / Solo BCBA economicsWhy this matters at solo scale

The case for outsourced billing at solo scale isn't about cost, it's about ceiling. A solo BCBA doing her own billing is capped at the caseload she can clinically manage plus bill. Removing the billing constraint:

  • Adds 10-14 hours/week of capacity
  • Recovers 15-25% of net revenue lost to denials and write-offs
  • Removes a sustained burnout vector that drives many solo practitioners back to W-2 employment

For most solo BCBAs, the ROI on a senior-partner-led billing engagement is positive in the first cycle and meaningful by the third.

Solo BCBA? Stop billing at 9pm.

A senior partner audits your last billing cycle in 30 minutes. Written diagnostic. No platform sales pitch.
