Code descriptions here are plain-language summaries. Payers add their own rules on who can bill, concurrent billing, modifiers and documentation. This page is educational, not billing advice — confirm details in your payer's policy and provider manual.
Who delivers 97153
A technician — typically an RBT — delivers the session under the direction of a BCBA. The BCBA designs the protocol; the RBT carries it out. Because RBTs need ongoing supervision, 97153 hours also drive RBT supervision requirements.
97153 vs. 97155
| 97153 | 97155 | |
|---|---|---|
| Delivered by | RBT / technician | BCBA |
| Purpose | Run the existing protocol | Change or refine the protocol |
| Client present | Yes, one client | Yes, one client |
When the BCBA joins an RBT session to adjust the protocol, some payers allow both codes at the same time and some don't. Read your payer's concurrent-billing policy. More in the 97155 guide.
