For as long as the current ABA code set has existed, the most skilled work a BCBA does has been unbillable. Reviewing a week of frequency data, deciding a target has plateaued, rewriting the protocol, walking the technician through the change: none of it has a code, so practices absorb it as overhead or stretch it to fit inside an assessment. That ends on January 1, 2027, when CPT 97180 takes effect.
The short answer. CPT 97180 covers adaptive behavior non-face-to-face services personally performed by a BCBA or other qualified health care professional, in 15-minute units: reviewing treatment data and session notes, modifying targets or protocols, determining the need for further assessment, developing discharge and transition plans, and reviewing revised protocols with technicians. The AMA published the code in the CPT 2027 code set on September 9, 2026. It is effective January 1, 2027. Rates, telehealth status, and payer coverage are still open and are settled payer by payer after CMS's final rule in November 2026.
TL;DR
- 97180 is new, official, and effective January 1, 2027. It is one of six new adaptive behavior codes in the CPT 2027 code set (the others are 97148, 97149, 97159, 97160, and 97173).
- It pays for work away from the patient. Data review, protocol modification, assessment decisions, discharge planning, and technician protocol review, in 15-minute units, personally performed by the qualified provider.
- Today that work is not billable outside 97151. The ABA Coding Coalition's own FAQ says so in plain terms.
- No rate exists. CMS proposed carrier pricing through 2027, so every payer sets its own number after the November final rule.
- The preparation is a documentation habit, not a software purchase. Practices that log indirect BCBA time at the task level in Q4 2026 will bill 97180 on day one. Practices that do not will reconstruct it.
How This Guide Is Sourced
Disclosure: VG Soft Co sells ABA practice management software (VGPM) and outsourced billing services (RCM). We wrote this because our own billing team needs it, and the last section says what we think practices should ask any software vendor, including us. Nothing here is billing or legal advice for your specific payer contracts.
The code facts come from the AMA's CPT 2027 release (September 9, 2026), the ABA Coding Coalition (confirmation of the six codes on September 10; the July 15 summary of CMS's proposed CY 2027 fee schedule, which printed the descriptor under placeholder 97X3X), the Coalition's billing FAQ on what is and is not billable today, and CMS-1848-P itself. CPT descriptors are AMA copyright, so the wording here is a paraphrase; the exact language and the code set guidelines publish in the 2027 CPT Professional Edition late in 2026.

What 97180 Covers
The code is defined by two things: who performs the work and where the patient is.
Who: a physician or other qualified health care professional, personally. In ABA that means the BCBA, BCBA-D, or licensed behavior analyst who holds the case. Technician time does not qualify, and delegated work does not qualify. If the BCBA did not do it, it is not 97180.
Where: away from the patient. 97180 is non-face-to-face by definition. The activities CMS listed when it proposed valuation for the code, and which the Coalition reproduced in July, are:
| Activity | What it looks like in practice |
|---|---|
| Reviewing treatment data and session notes | Reading the week's graphs and technician notes for a client, checking mastery criteria, spotting drift |
| Modifying treatment targets or protocols | Rewriting a target, changing a prompt hierarchy, retiring a mastered program, adding a replacement behavior |
| Determining the need for additional assessment | Deciding a client needs a new functional assessment or a reassessment before the authorization period ends |
| Developing discharge or transition plans | Writing the fade plan, coordinating a school transition, preparing the family for reduced hours |
| Reviewing revised protocols with technicians | Walking the RBT through the protocol change, without the client present |
Each 15 minutes of that work is one unit. What the code set guidelines say about minimum time per unit, same-day reporting alongside 97155 or 97151, and any cap on units per period is not public until the Professional Edition publishes. Do not assume the 8-minute convention applies until you read the guideline.
Why This Is the Most Consequential of the Six New Codes
The other five new codes refine things ABA practices already bill. 97148 and 97149 replace the team assessment concept behind 0362T. 97159 and 97160 replace the team treatment concept behind 0373T. 97173 splits direct provider treatment out of 97155. Each matters to the practices that use them, but the revenue they touch already exists.
97180 creates revenue that does not exist today. The Coalition's guidance for the current set is unambiguous: modifying written protocols, writing session notes, updating goals or plans, reviewing data, creating materials, and supervising technicians without the patient present are not billable with any code except 97151, and 97151 only covers the non-face-to-face portion of an assessment. The rest is bundled into the face-to-face rates and, in the Coalition's words, reimbursement for those codes is meant to capture both.
Whether that bundling ever actually covered the work is the argument every BCBA owner has had with a spreadsheet. A BCBA carrying 12 to 15 clients spends a meaningful share of each week on exactly the activities in the table above. Under the current set, that time has no line on a claim. Under 97180 it does.
Two cautions keep this honest:
- Payers may treat 97180 as a reallocation, not an addition. If a payer believes indirect time was already priced into 97153 and 97155, it can pay 97180 while trimming elsewhere, cap 97180 units tightly, or simply decline to cover it. Carrier pricing gives each payer that room.
- Authorization comes first. Every unit of 97180 you bill in January needs to be in an authorization written in late 2026. Payers have not published 97180 authorization policies yet. Ask now.
What Changes for 97155
97180 does not exist in isolation. The revised 97155 descriptor, as summarized in the code-set analyses published after the AMA release, narrows to direction of a technician plus analysis by the qualified provider, and the direct-treatment component moves to new code 97173. Read the three together:
- 97173: the BCBA is face to face with one patient, delivering treatment with analysis.
- 97155: the BCBA is directing a technician and analyzing, with the patient present.
- 97180: the BCBA is working on the case with nobody in the room.
That split is cleaner than today's, where 97155 stretched to cover supervision, direct treatment, and some analysis, and payers argued about which part they were paying for. It also means your scheduling and billing logic has to know which of the three a BCBA's block of time was, which is a documentation question before it is a software question. Our session notes mistakes guide covers the failure modes that already trigger denials on 97155; 97180 adds a new one, which is a claim with no session record to support it.
What Is Still Open
Four things are not settled, and all four land in or after CMS's final CY 2027 Physician Fee Schedule rule, expected in November 2026. The comment period on the proposed rule closed September 14.
- Rate. CMS marked 97180 and the other new codes with a "C" in place of a work RVU and proposed extending carrier pricing for adaptive behavior codes through 2027. There will be no national Medicare rate. Each Medicare Administrative Contractor, each state Medicaid program, and each commercial payer sets its own, and most ABA revenue is Medicaid and commercial anyway. Expect a spread.
- Telehealth. CMS proposed keeping 97151 through 97158 on the permanent telehealth list and said nothing about the six new codes. The Coalition said it would request permanent status for all six. For 97180 the practical question is whether any payer attaches a place-of-service or location requirement to remote clinical review.
- Guidelines. Unit thresholds, same-day rules, and any restriction on reporting 97180 during an assessment period covered by 97151 are in the code set guidelines, which publish with the Professional Edition. Until then, do not build billing rules on assumptions.
- Payer adoption timing. State Medicaid programs and commercial plans publish 2027 fee schedules after the CMS rule, and some will lag January 1. Vermont and Texas Medicaid tightened concurrent-billing rules mid-2026 with little notice, so treat every payer's 97180 policy as unknown until you hold it in writing.
How to Prepare in Q4 2026
You cannot bill a code that is not live, but the preparation that determines whether you bill it well in January is available now.
1. Start logging indirect BCBA time at the task level, today. This is the single highest-value action and it costs nothing. For every client, every BCBA records the date, start and stop time, the activity in the table above, and the decision that came out of it. A weekly lump ("8 hours indirect") is useless; "Tuesday 2:10 to 2:40, reviewed 9 sessions of mand data for J.R., moved target 4 to maintenance, revised prompt level on target 6" is a 97180 record with a code number swapped in. Three months of that gives you a baseline for authorization requests and a documentation habit your payers will audit against.
2. Ask each payer three questions in writing. Will you cover 97180 for dates of service on or after January 1, 2027? What unit limit or authorization structure will apply? What documentation will you require? Most payers will not have answers before November, but the question on file starts the clock, and the written answer is what you bill against.
3. Audit what your documentation system can and cannot record. Nearly every ABA platform builds its notes around a scheduled appointment with a client, a start time, an end time, and a technician. 97180 work has no appointment and no technician. Ask whether your system can produce a signed, timestamped, client-linked documentation record that is not attached to a session, whether it can version protocols so a change is a tracked event, and whether BCBA time can be captured against a billing code rather than a generic "admin" bucket. Our documentation requirements by payer guide covers what payers already enforce for the current codes.
4. Map the three-way split before December. Decide how your practice classifies a BCBA's hour: face to face with the client (97173), directing a technician with the client present (97155), or working the case alone (97180). Write it down, train on it, and make sure the scheduling system can represent all three. Practices that leave this to individual BCBAs will bill inconsistently and invite audits.
5. Get to a Coalition webinar. The ABA Coding Coalition is running explainer sessions through ABAI (September 21), APBA (September 28), and CASP (September 30, invitation only). They will be the first detailed public walkthrough of the descriptors and guidelines from the people who wrote the code change application.
What to Ask Your Software Vendor
Every practice management vendor, including VGPM, owes its customers a clear answer on 2027 readiness, and the answer should be a release date, not a roadmap slot. The questions that separate a real answer from a reassuring one:
- Will 97148, 97149, 97159, 97160, 97173, and 97180 be in the code table before January 1, with the add-on relationships between 97148 and 97149 and between 97159 and 97160 enforced?
- Can a BCBA record billable time against 97180 with no appointment attached, and does that record carry the client, start and stop times, the activity, and a signature?
- Can the system enforce that 97180 is billed only by a qualified provider, not a technician?
- When protocols change, is the change a tracked, timestamped event linked to the data that prompted it?
- How will authorization tracking handle a code with per-period unit limits that vary by payer?
If a vendor cannot answer the second question, your BCBAs will be logging 97180 in a spreadsheet next to the system you pay for. That is manageable for a quarter and untenable for a year.
The Bottom Line
97180 is the first time the ABA code set has recognized that the BCBA's analytical work is the service, not the overhead around it. The number is published, the effective date is fixed, and the work it describes is already happening in your practice every week. What is not fixed is what any payer will pay for it, when, and under what documentation rules, and none of that arrives before November.
The practices that come out ahead will not be the ones with the best software or the sharpest biller. They will be the ones whose BCBAs spent Q4 2026 writing down what they already do, in the format a payer can pay for. Start this week.
