97153 CPT Code: Description, Who Can Bill It, 2027 Status

97153 is the workhorse of ABA billing. For most practices it is the largest line on every claim and the code the rest of the day is built around. It is also the code that people most often ask about, usually in four forms: what is its description, who can bill it, how it differs from 97155, and whether it survives the 2027 code changes. This guide answers each with sources. Everything is as of November 2, 2026, and payers vary on most of the details below.

The 97153 description

The ABA Coding Coalition's September 11, 2026 conversion table gives the current descriptor: adaptive behavior treatment by protocol, administered by a technician under the direction of a physician or other qualified healthcare professional, face-to-face with one patient, each 15 minutes. The key elements:

• Treatment by protocol. The technician implements a written treatment protocol. The Coalition's guidance defines a protocol as a written description of procedures for a patient's goals and the implementation of those procedures with the patient.
• Technician-administered. The person with the patient is a technician, typically a registered behavior technician, working under a qualified healthcare professional (QHP).
• Face-to-face, one patient. Group delivery to two or more patients is 97154.
• Per 15 minutes. One unit is 15 minutes. A two-hour session is eight units.

The guidance is also specific about what is not 97153: reviewing session notes from earlier sessions or adjusting written protocols are non-face-to-face activities that the patient's presence is not needed for, and they do not belong to the technician's code.

Who can bill 97153

There are two questions inside this one: who can deliver it, and whose name goes on the claim.

Who can deliver it

By its descriptor, a technician under QHP direction. The Coalition's table lists those present as the client and the technician, and adds that a QHP may substitute for the technician. If a technician cancels and a QHP covers the session, the guidance says the time is reported as 97153 "even though the session was conducted by a QHP," if the QHP is simply serving as a proxy and running the protocol. If the QHP also analyzes whether targets, goals or protocols need to change, that is a different service (97173 in 2027).

Whose name is on the claim

This is set by each payer and state, not by CPT. Some payers want the supervising BCBA as the billing or rendering provider with the technician's work reported under that provider; others enroll or credential technicians in some way; some require a modifier showing the rendering person's education level. The Coalition's conversion table notes that modifiers commonly used with these codes include HM (high school education), HN (four-year degree), HO (master's degree) and HP (doctoral degree), and its guidance adds that some payers require modifier codes to show a QHP or higher-level provider rendered a technician-administered code. Whether your payer uses them, and how, is in its provider manual or contract. The guidance also notes that 40 states and the District of Columbia have licensure laws for behavior analysts, while in other jurisdictions payers may require certification from the BACB or another national certifier.

Two practical rules follow. First, the person on the claim must be someone the payer has enrolled or recognizes for that service on the date of service. Second, the session note must make clear who delivered the service, who supervised it and for how long. The BACB handbook, not this article, is the authority on what supervision of an RBT requires.

Can you bill 97153 and 97155 together?

This is the other highest-volume question, and the answer is "yes, if two different people and both descriptors are met."

• Different people, same time: A BCBA joins a session to direct the RBT, observes the patient's responses and coaches the technician. The RBT's minutes are 97153 and the BCBA's minutes are 97155. The Coalition's 2027 guidance says "Yes, 97153 and 97155 may be reported concurrently if the criteria in the descriptors of both codes are met."
• Same person, same time: Not allowed. The same guidance says "A single QHP may not report 97153 and 97155 concurrently." North Carolina Medicaid's October 12, 2026 bulletin on Clinical Coverage Policy 8F says the same in payer terms: "A single rendering provider may not bill 97153 or 97154 and 97155 for the same time period," while allowing 97153 or 97154 with 97155 when a paraprofessional provides the 97153 or 97154 while observed.
• Different time: A QHP who treats a patient for 30 minutes and later directs a technician for 30 minutes is not concurrent. Each block is documented and reported on its own.

Payers may layer their own limits on top: ratios of 97155 to 97153 hours, requirements that 97155 happen on a schedule, or prior authorization of each code. These are policy, not CPT, and they differ by payer. The detail on the supervision-side code is in our guide to CPT code 97155.

Status in 2027

• The number stays. 97153 remains 97153 on January 1, 2027, and it remains per 15 minutes, face-to-face with one patient.
• The descriptor loses a phrase. The 2027 wording in the Coalition's conversion table reads "administered by technician, face-to-face with one patient, each 15 minutes," without "under the direction of a physician or other qualified healthcare professional."
• 97155 changes underneath it. From January 1, 97155 is used only for a QHP directing a technician with the patient present, and is always reported with a technician code such as 97153. The Coalition's guidance says 97155 "will ALWAYS be reported with another technician-delivered CPT code and will not be reported on its own under the 2027 code set."
• QHP hands-on work moves to 97173. A QHP who treats one patient alone with analysis reports 97173. A QHP who only covers for an absent technician reports 97153.
• Non-face-to-face review moves to 97180. Reviewing technician-delivered session data for clinical decision-making can be reported per 7-day period using 97180, per the guidance.

The whole transition, with the full crosswalk and a checklist, is in our guide to the ABA CPT code changes for 2027. Remember that a code number is not a rate, and payers do not all have to load the 2027 codes on the same day.

What the money looks like: payers vary

There is no single 97153 rate. As one dated example, Highmark's provider notice (posted August 17, 2026) set new commercial PPO rates for 97153 effective October 16, 2026: in Pennsylvania $16.59 in an office setting and $15.73 in a non-office setting, in West Virginia $14.53 and $13.78, and in Delaware $15.73 for both. Highmark says the update does not change eligibility, benefits, medical necessity criteria, authorization requirements, coverage policies or documentation expectations. The notice does not state the billing unit. Those numbers are one payer, three states and commercial PPO products only; they are not a benchmark for Medicaid or any other plan, and your contract governs your rate. Note the lesson: the place of service can change the rate for the same code.

A 97153 documentation checklist

Many claim problems trace to the note rather than the code. For each session confirm:

1. The date, start and stop times, and the setting match what was scheduled and what you billed.
2. The technician and the supervising provider are identified, with credentials.
3. The note shows the protocol targets that were worked on and the data collected, consistent with the treatment plan.
4. Units billed equal the documented minutes under your payer's rounding rule.
5. The units fit inside the authorization on that date of service.
6. No other service overlaps the same minutes for the same provider.

When claims do come back, work the cause rather than the claim; our guide to ABA billing denials covers the usual culprits, and our ABA CPT codes reference lists the rest of the family.

Common 97153 mistakes

• Billing the schedule instead of the session. The appointment said two hours; the child left after 90 minutes. Units follow documented minutes.
• Letting two services share minutes. The technician and the BCBA each bill their own code in the same window only when two different people deliver them; one person never bills two codes for the same minutes.
• Treating a stand-in as a different service. A BCBA who covers a cancelled technician and simply runs the protocol reports 97153; the 2027 guidance reserves 97173 for treatment with analysis.
• Using the wrong rendering provider. Check which person the payer expects on the claim, and that they are enrolled for the date of service.
• Ignoring place of service. As the Highmark example shows, the same code can carry different rates in an office and a non-office setting.
