On January 1, 2017, the Louisiana Department of Health and Hospitals (DHH) cut Medicaid reimbursement rates for applied behavioral analysis (ABA) by more than 20%. According to a memo to ABA provider organizations, the new rates are based on the average commercial rate for these services across the state. The state Medicaid program also adopted new temporary ABA Current and Procedural Terminology (CPT) codes. Under the previous fee schedule implemented in April 2014, the codes and rates for ABA were as follows: H2019 at $18.00 per 15-minute unit and H2019 (w/modifier) at $12.50 per 15-minute . . .
