No. The services provided by physical therapist assistants (PTAs) cannot be billed incident-to a physician/non-physician practitioner’s (NPP), because PTAs do not meet the qualifications of a therapist. Only the services of a licensed/registered physical therapist can be billed incident-to a physician service. PTAs may not provide evaluation services, make clinical judgments or decisions, or take responsibility for the service. PTAs act at the direction and under the supervision of the treating physical therapist and in accordance with state laws. The services of the PTA are only billable when provided under the direct supervision of the physical therapist and under their NPI number.
