BT vs RBT: what a behavior technician needs in Delaware

Only in some situations. See the detail below.

Medicaid: an ordinary uncredentialed BT is not the approved technician pathway; DMMA expressly rejected uncertified assistants working under supervision. Commercial-mandate standards: 16 DE Admin. Code 2102 permits qualifying supervised BTs to implement ABA plans without expressly requiring RBT certification. This does not establish independent billing or guaranteed contractual acceptance. Highmark's commercial reimbursement notice, published August 17, 2026 and effective October 16, 2026, describes CPT 97153 delivery by RBTs or other qualified behavioral-health technicians under qualified supervision; it does not define a complete non-RBT credentialing pathway.

• For the commercial-mandate pathway, 2102 section 3.3 requires BCBA/BCBA-D supervision and supervisor verification of technician qualifications.
• Section 3.3.1 requires at least 1.5 supervision hours per 10 direct-treatment hours weekly; when prescribed and delivered ABA is under 10 hours weekly, at least one supervision hour is required.
• Medicaid RBT qualification and supervision requirements are described in medicaid_aba; commercial technician screening and training requirements are described in practice_requirements.

CMS-approved SPA DE-16-010, effective October 1, 2016 and approved January 12, 2017, covers medically necessary ASD assessments, behavioral plans and treatment. Qualified categories include BCBAs, supervised BCaBAs and RBTs; specified licensed physicians, physician assistants, advanced practice nurses, psychologists, clinical social workers and mental-health counselors; and qualifying psychological assistants. Providers must remain within their scope. RBTs are excluded from independently providing the ASD assessment and behavioral plan of care. The SPA requires prior authorization for plans exceeding 40 hours weekly; this does not establish that lower-hour services escape current payer authorization requirements.

Yes.

For the Medicaid behavior-technician pathway, the approved SPA specifies Registered Behavior Technician certification. DMMA's October 2016 final-order response expressly rejected using unlicensed, BACB-uncertified assistants merely because a qualified practitioner supervises them. Other qualified professional categories are separate pathways. Delaware First Health's enrollment notice dated October 21, 2024 directs providers to the DMAP portal's Provider Enrollment / MCO Only Provider Enrollment Application. Billing entities must register applicable NPI/taxonomy/service locations; nonbilling rendering providers listed on claims must register their main practice location. This does not establish independent billing privileges for RBTs.
