Read before using these numbers

The Fee Schedule link on Maryland’s own ABA page points at a January 2024 file and returns a 404. The live schedule is inside the provider manual effective 1 February 2026, which is what is cited here.
97153, 97154 and 97156 are tiered by who delivers the service. A single headline number would overstate what a technician-delivered hour pays.
97156 has two rates depending on whether the child is present; the higher requires modifier U2.
Every row carries a daily maximum in units.
Maryland’s ABA program is administered by Carelon Behavioral Health Maryland as the state’s ASO.
