BT vs RBT: what a behavior technician needs in Montana

We could not verify this yet - check with the state Medicaid agency and the payer you bill.

As of 2026-10-21, the sources distinguish supervised BT practice from payer reimbursement. Montana's board definition of BT does not expressly require BACB certification. For Medicaid ABA, ARM 37.34.1902(17) defines an RBT as BACB-certified; ARM 37.34.1918(2)(b) identifies BCaBAs and RBTs as supervised service providers, and ARM 37.34.1930(3) makes the BCBA responsible for RBT services and billing. These provisions were included in the April 2025 rule notice adopted as proposed in October 2025, retroactively effective March 1, 2025. The final Medicaid manual, updated 09/01/2025, confirms billing under the BCBA's NPI. No unregistered-BT billing exception or certification grace period was established by the fetched sources. Commercially, BCBSMT's posted Clinical Service Request Form lists line-staff qualifications without expressly listing RBT certification and requires the billing supervisor or clinic to attest that staff qualify. This is not conclusive authorization for an uncertified BT under every current contract. PacificSource's Montana-applicable policy, approved March 2026, requires BCBA management and supervision but does not resolve non-RBT eligibility. A statewide, all-payer yes/no answer remains unverified.

• ARM 24.189.301(3) defines a BT as a supervisee implementing behavior-analytic services; BTs do not design intervention or assessment plans.
• MCA 37-17-405(2) requires BT supervision by a Montana-licensed behavior analyst or a licensed psychologist certified by the American Board of Professional Psychology in behavioral and cognitive psychology. Medicaid separately specifies BCBA oversight.
• ARM 24.189.950, adopted in December 2023, requires supervisors to report supervisees within five business days, assume professional and legal responsibility, meet face-to-face at least monthly, and maintain written supervision agreements covering methods, delegated authority, limitations and meeting frequency/duration. Agreements must be retained for seven years after supervision ends.
• The fetched board provisions establish supervision and reporting duties; they do not establish a separate BT license or expressly make BACB RBT certification a condition of the board's BT definition. This does not establish payer eligibility.

As of 2026-10-21, the DPHHS ABA page identifies a licensed Board Certified Behavior Analyst (BCBA). The current ABA Services Manual (updated September 1, 2025) covers services performed by BCBAs, BCBA-Ds, BCaBAs and RBTs. RBTs practice under direction and close supervision of a BCBA, who assumes full professional responsibility; BCaBAs also work under a BCBA. The current manual also defines an intermediate-professional category that includes graduate students working toward certification, but this does not establish independent billing authority. All services are billed under the BCBA's National Provider Identifier (NPI).

The manual defines RBT as an individual with a paraprofessional certification in behavior analysis. No explicit permission for non-RBT technicians to deliver services, and no grace period, was located in the cited sources. Needs confirmation from the ABA Program Officer ((406) 444-3878).
