In this case, the Claimant provided a prescription from her treating physician for massage therapy treatment. The employer stipulated that the treatments were causally related to the Claimant's work injury. The Court found that a massage therapist is not a medical practitioner as defined in the Act. The Court noted that the massage therapist was not performing her services under referring physician’s supervision. The Court held that a doctor's prescription does not bring services within the definition of medical services. The Court reasoned that if an individual is not licensed or otherwise authorized to provide health care services in the Commonwealth, her services are not reimbursable under the Act. In the absence of a license, the provider's services are not reimbursable as services rendered by a health care provider. The Court concluded that should the Commonwealth issue state licensure for massage therapists, the outcome in future cases may be different. Until such time, employers are not required to pay for massage therapy treatment.
