A therapist may bill for more than one therapy service that was furnished within the same 15-minute time period when "supervised modalities" have been defined by the American Medical Association (AMA) as “untimed and unattended and not requiring the presence of the therapist” (CPT codes 97010 to 97028). One or more supervised modalities may be billed in the same 15-minute time period with any other CPT code, timed or untimed, requiring constant attendance or direct one-on-one patient contact. However, any actual time the therapist uses to attend one-on-one to a patient receiving a supervised modality cannot be counted for any other service provided by the therapist.
