Question: If the outpatient clinic is being supervised by a physician is it OK for PT tech’s or aides to treat patients? If so does the therapist also need to be supervising?

Answer: Absolutely NO!
1) Medicare does not pay for services provided by an aide or tech, only those of a qualified professional.
2) If a physician is billing incident-to, then those services must be provided by a physical therapist, not even a physical therapist assistant will be accepted.
3) To bill Medicare for services provided by a tech/aide is Medicare fraud, no ifs, ands or buts.
