BT vs RBT: what a behavior technician needs in Ohio

Only in some situations. See the detail below.

State practice law: ORC 4783.02(B)(4) exempts an individual practicing ABA who is supervised by a certified Ohio behavior analyst and acting under that analyst's authority and direction; the supervisor signs an attestation (4783.02(C)). (B)(5) exempts a direct care provider or family member implementing components of a treatment plan. So, as of 2026-10-21, the Chapter 4783 exemption does not itself require a technician to hold an RBT or a state credential, but it is conditional: supervision, authority and direction, and the signed responsibility attestation are substantive conditions. The exemption does not establish permission to bill a payer for an uncertified technician. Payer rules are stricter and payer-specific: CareSource's Ohio Medicaid policy describes technician-level treatment as delivered by a BACB-certified RBT supervised by a BCBA. ODM's July 2026 proposal (not final) would require RBT certification and would remove the exam-eligible window. The May 2025 draft proposed a grace period of ninety calendar days from the date of exam eligibility (not from hiring) for 'exam-eligible RBTs'. The draft text describes these as technicians who completed the initial competency assessment, and draft form ODM 10391 documents that the technician applied to take the exam with the BACB. Because the ODM ABA rules are not final and the opened sources did not establish an operative Medicaid grace period, the allowed BT window for Medicaid billing is unconfirmed.

• Under the Chapter 4783 practice exemption, no state registration is required for technicians, but the technician must be supervised by a certified Ohio behavior analyst acting with authority and direction, and the supervisor must sign an attestation (ORC 4783.02(B)(4), (C)); this does not establish permission to bill for an uncertified technician
• Supervisor must keep a written supervision plan per client treatment plan and supervision records for five years following termination of supervision (OAC 4783-6-02; OAC 4783-3-01 defines the supervision plan as a written document)
• Payer: BACB-certified RBT supervised by a BCBA is the technician level in CareSource's Ohio Medicaid policy (payer-specific); the proposed ODM rule (7/30/2026 presentation, not final) would require RBT certification; the May 2025 draft's 90-day period ran from exam eligibility and required an exam application (ODM 10391); no operative Medicaid grace period was confirmed

As of 2026-10-21, per the CareSource Ohio Medicaid ABA reimbursement policy OH MCD-PY-1638 (effective 2026-09-01; this describes CareSource only, not every Ohio Medicaid arrangement): behavior identification assessment by a BCBA; ABA treatment is one-on-one by a BCBA, a BCaBA supervised by a BCBA, or an RBT supervised by a BCBA; family guidance by a BCBA; claims need qualification modifiers. ODM's Provider Stakeholder Office Hours deck of 2026-07-30 says ODM paused its 2025 draft ABA rule to re-evaluate, and that the revised draft removes the 'exam-eligible RBT' option and would require RBT certification for Medicaid ABA technicians, require organizational ABA providers to hold CARF or Joint Commission accreditation, require supervision per BACB, and require ABA be billed with ABA codes rather than community behavioral health codes. The May 2025 draft rule (5160-34-01) was marked 'DRAFT - NOT YET FILED' and had allowed an 'exam-eligible RBT' to work up to 90 calendar days. These are proposals, not adopted rules.

It depends. See the condition below.

Not fixed by a final ODM rule that could be confirmed. CareSource's policy treats an RBT supervised by a BCBA as the technician level for treatment; other MCOs were not checked. ODM's July 2026 proposed revision would require RBT certification (no exam-eligible grace period); the 2025 draft had a 90-day exam-eligible allowance. These are proposals only. Confirm current status with ODM and each MCO.
