Corrections

We said no ABA platform publishes its pricing. Several do.

We published "Not one of the twelve platforms in this guide publishes its pricing. Every single one is quote-only."

It should have said that most do not. Several publish per-seat rates on their own websites — Office Puzzle, for one, lists $19.99 per user per month.

What went wrong. The claim was almost certainly true when written and was never re-checked. Pricing transparency is exactly the kind of fact that changes without anyone announcing it, and an absolute — "not one", "every single one" — is the most fragile sentence you can write about a market. It was found while building a replacement comparison page, not by a reader.

Also. Several tool listings still carry a machine-readable flag saying the vendor does not publish pricing. Those are being re-checked one vendor at a time against each vendor's own site, and we are not flipping any of them on inference.

Our correction to Florida's rate was itself wrong

We published $12.19 per 15 minutes for CPT 97153 — the figure we moved to on 2 August when fixing the error described below.

It should have said $12.26 per 15 minutes, $49.04 an hour.

What went wrong. The same failure as the original, one code over. $12.19 is what Florida pays for 97152, 0362T and 0373T — three other codes on the same page. In correcting a code mix-up we introduced a second code mix-up, and then rejected the right answer: a research pass had proposed $12.26 and we ruled it out, believing it belonged to a different year. It did not. Florida prints $12.26 on both the 2025 and the 2026 schedule.

Why it took three days. Because we never reopened the PDF. The 2 August fix was made by reasoning about which figure belonged to which code rather than by reading the document again — the exact substitution this site's first rule exists to forbid. The error was found only when we returned to restore the withdrawn rows.

Also. The correction below states that $15.37 is Florida's rate for 97156. That is wrong too. $15.37 is 97155 with modifier HN, the assistant-analyst rate for protocol modification; 97156 with modifier HN is $15.24. The original error was real and the size of it was right — the code we blamed it on was not.

What changed as a result. Florida's page now carries all 23 rows from the 2026 schedule, including the 97155 and 97156 rows withdrawn in July, each read twice from the source PDF by two different extraction methods. We also compared the 2025 and 2026 schedules line by line and confirmed Florida changed no ABA rate between them.

Florida's Medicaid rate was overstated by 26%

We published $15.37 per 15 minutes for CPT 97153, Florida's core direct-therapy code, or $61.48 an hour.

It should have said $12.26 per 15 minutes, $49.04 an hour. At the time we published $12.19, which was also wrong — see the entry above, dated 5 August.

What went wrong. A code mix-up. $15.37 is Florida's rate for 97155 with modifier HN, protocol modification by an assistant behavior analyst — a different service delivered by a different practitioner. The figure was read from the correct schedule but attached to the wrong code. It was live for roughly two weeks, on the state holding a quarter of the country's ABA organizations, in the dataset this site's credibility rests on. It was caught by re-reading the source rather than by any reader.

Also. Florida's 97155 and 97156 rows were withdrawn at the same time pending a re-read, rather than corrected on a guess. They were restored on 5 August.

Indiana's rates had been superseded for three months

We published $17.06 per 15 minutes for 97153, transcribed correctly from IHCP bulletin BT2023169.

It should have said $16.04. Indiana cut all non-group ABA rates by 6% effective 1 April 2026 under bulletin BT202627 — three months before our own page claimed it had been checked.

What went wrong. We verified the figure against the document we cited and never asked whether that document was still current. Codes 0362T and 0373T were also in the cited bulletin but missing from our table with nothing explaining the absence, so the page implied Indiana does not pay them.

Nine citations pointed at documents containing no ABA rates

A citation that goes nowhere useful is a broken promise, and nine of ours were.

• Arizona cited the Behavioral Health Outpatient schedule, which contains only H, S and T codes and no ABA CPT codes whatsoever.
• Texas cited the Outpatient Behavioral Health schedule. The ABA codes are on a different schedule entirely, Autism Services.
• Georgia cited the January 2018 ASD policy manual, which prices ABA against Category III codes the AMA deleted at the end of 2018.
• Maryland's own fee schedule link returns a 404; the live schedule is inside a provider manual.
• Ohio cited a package stamped "DRAFT — NOT FOR FILING" with proposed figures and a blank effective-date column.
• West Virginia's policy link returns a 404.
• Nevada and Washington cited billing guides that list every ABA code and no dollar amount anywhere.
• Michigan's cited document refuses all non-browser requests.

All nine now cite documents that contain the figures.

The company directory listed one percent of the companies

We published 234 companies, those with three or more registered locations.

The registry holds 17,781. Every single-site company was invisible, which meant a reader searching for a real company they knew existed would conclude it was not registered. Two were reported to us by name.

What changed. Every registered organization is now listed, across state and city pages, and searchable. Street addresses are still withheld for companies with fewer than three locations, because those may be home addresses — that protection was the reason for the threshold and it has been kept, while the exclusion has gone.

A company history section failed its own audit

An audit of 141 claims across the company pages found fewer than half were supported by the source cited for them, and ten were contradicted by their own citation. Among them:

• Motivity's headquarters was cited to a page that states no location anywhere.
• The NPAWorks page said a chief executive "was quoted without being named". The cited release names and quotes her.
• Passage Health's founding year was wrong by one year, and its funding total double-counted a note that later converted.
• CentralReach's acquisition price was labeled gross when the filing says net of cash acquired; its headquarters city was stale.
• Artemis ABA described someone as a co-founder when the company's About page says he joined after founding.

The section was held back from publication until every claim was re-verified against its source. Verification before publication is now the standing rule.
