Final answer:
The statement is true, a receipt should be issued for services within the scope of practice and signed by the practitioner who performed them.
Step-by-step explanation:
The statement that a receipt can only be issued for the services that fall within the scope of practice and signed by the MT performing them is True. A receipt serves as proof of payment for services provided, and it is professional and legally required that these services are within the scope of the practitioner's capabilities and qualifications. Furthermore, the signature of the performing Massage Therapist (MT) on the receipt verifies that the identified individual provided the services. This is critical for accountability and for the client to have the assurance that the practitioner is properly qualified to offer the services rendered.
