28 Pa. Code § 25.201
Since the legislature obviously believes that the license already held by physicians and audiologists is adequate proof of their competence to fit patients with hearing aids, they are not required to take a qualifying examination prior to obtaining a hearing aid dealers certificate. Pennsylvania Hearing Aid Dealers Association, Inc. v. Department of Health, 417 A.2d 1340 (Pa. Cmwlth. 1980); affirmed 430 A.2d 1150 (Pa. 1981).
