Autism Stats queried its saved HHS ABA extract for exactly CPT 97151, 97152, 97153, 97154, 97155, 97156, 97157 and 97158. For each calendar year 2021 through 2024, we summed TOTAL_PAID after casting each value to a two-decimal fixed-point number. We compared those sums with PaidTotal in CMS Table 3 and checked the eight-code scope against Table 7. Ratio (%) = HHS sum / CMS total x 100, rounded to two decimal places in the CSV. The August 2026 CMS workbook was downloaded again on November 2 and matched the saved workbook byte for byte. This is a secondary analysis of published aggregates, not a claims audit.
