Effective January 1, 2019:
- 8 modified codes approved as Category I (97151–97158)
- 2 modified codes to remain Category III (0362T, 0373T)
To help achieve consistency in use and implementation of the new codes, the work group prepared a coding conversion crosswalk for practitioners to navigate changes from prior billing codes.
These changes were significant in encouraging more consistent adherence to the descriptors as approved by the CPT Editorial Panel and reducing denials of ABA services on the premise that they lack evidence of efficacy and medical necessity.
