The 90-Day Plan

How the $1.4M got recovered.

  • Days 1-30 · Audit and integrate. 18-month takeback log mapped. EHR, CredPro, and CentralReach connected to the LLM Gateway.
  • Days 31-60 · Gate live. Three-way match enabled site by site. Parallel run vs the prior workflow for safety. Five senior coordinators trained.
  • Days 61-90 · Tune and escalate. Hold queue tuned site by site. Payer-specific supervision policy rules added. Recovered claims worked back into appeals.
  • Months 4-18 · Compound. $1.4M cumulative reversal. Zero auth-expired sessions billed. Denial rate held at 3.9%.

01
Week 1 · Discovery

Map the leak.

18-month takeback log pulled. Root cause tagged per CPT. EHR, CredPro, CentralReach connection scoped.

02
Week 4 · Gate live

First catches.

Three-way match enabled at four pilot sites. Two takebacks blocked in the first week. Parallel run vs prior workflow.

03
Month 3 · Rollout

All 42 sites.

Payer-specific supervision rules added. Denial rate at 6.4 percent. Recovered claims worked back into appeals queue.

04
Month 6 · Steady

3.9% denial floor.

Zero auth-expired sessions billed. NCR at 98 percent first-pass. Cash days from 52 to 28.

We had been writing off roughly $80K a month for 18 months. The gate caught it in week four. By month six we had stopped budgeting for takebacks at all.

Operating postureHow the work actually changed.

TAKEAWAY Coordinators stopped chasing takebacks. The gate does the work.
BEFORE · MONTH 0

7.8% post-pay takeback rate

  • Auths checked manually at coding time
  • Supervision ratio audited quarterly, not at submission
  • EHR session notes reconciled at month-end
  • Takeback letter was the first signal of a gap
  • $78K per month rolled into bad-debt forecast
AFTER · MONTH 6

0.4% audit-recovery rate

  • All three sources gated before submission
  • Real-time supervision ratio block at session save
  • Session note alignment validated at submission
  • Hold queue is the only place a gap surfaces
  • Takeback line item removed from forecast

Common questionsFrequently asked: three-way match.

What is the three-way match?
A gate that confirms three things agree before a 97153 claim ships: active authorization, payer-required supervision ratio, and the EHR session note for that date, time, location, and provider. Any disagreement holds the claim.
Why is this the highest-leverage control for ABA?
The most expensive ABA takebacks happen when one of those three sources contradicts the others. Standard scrubbers do not catch silent auth expiry, ratio drift, or timestamp mismatches. The three-way match catches them deterministically before submission. The gate ships as standard scope in ASP-RCM's ABA therapy billing services.
How does this connect to CredPro v6?
CredPro v6 carries BCBA, BCaBA, RBT certification status, the BACB credential lookup, and supervising-BCBA assignment per RBT. The match pulls those facts at submission time, not from a stale spreadsheet.
Why anonymize the client?
The MSA includes reciprocal confidentiality. Numbers and timeline are real. A senior partner can host a reference call under NDA at late-stage diligence.
How long until we see results?
Visible denial-rate movement starts in week three. Steady-state shows up by week ten. The $1.4M figure is cumulative across 18 months.
What does the free audit look like for ABA?
Send 90 days of denial data with CARC and RARC, your authorization log, supervision ratio report by RBT, and provider roster. You get a 4-page written audit inside 30 days: denial taxonomy by root cause, recoverable revenue, authorization gap analysis, supervision compliance, 90-day fix plan.
Does this only work for multi-site chains?
No. The match logic is identical at any scale. Single-site practices, multi-state chains, and IDDs all run the same gate. Economics shift with volume; the discipline is the same.

Want the same audit applied to your data?

A free 30-day audit. Send 90 days of denial data and your provider roster. We return a 4-page written audit: denial taxonomy by root cause, recoverable revenue, authorization gap analysis, 90-day fix plan. Yours to keep. No SDR follow-up.
