Read before using these numbers

The previously cited URL (https://medicaid.ms.gov/providers/fee-schedules-and-rates/) is the correct agency index page and is live, but it holds no rates itself. The ABA rates are inside the Comprehensive Fee Schedule workbook linked from it.
A reader who went to the obvious file — the Behavioral Health Services Fee Schedule, July 2026 (WEB-Behavioral-Health-Services-Fee-Schedule-JULY-2026-FNL-.xlsx) — would find nothing. A raw search of every XML part of that workbook returns zero hits for 97151-97158, 0362T and 0373T. ABA is priced only in the Comprehensive Fee Schedule.
Each ABA code appears twice, under two Rate Types. DEF (Default) is the professional/practitioner price; OPP is Outpatient Hospital Pricing under Mississippi's OPPS. Do not mix the two — the OPP figures group several unrelated codes at the same APC price ($77.15 for 97151, 97152 and 97153 alike).
The workbook has no unit column. Only 0362T and 0373T carry "EA 15 MIN" inside their printed short descriptions. For 97151-97158 the document states no unit; the DEF figures should not be published as 15-minute rates without a further source.
The workbook title says JULY 2026 but per-row Begin Dates run from 07/01/2019 to 07/01/2026, so there is no single effective date for the ABA block.
97151 ($34.18) and 97152 ($41.74) carry Begin Dates of 2020 and 2019 and are markedly higher than 97153 ($15.08); if these are 15-minute units that is $136.72/hour for assessment. Treat with care until the unit is independently established.
