63 Pa. Stat. § 1114.2
The board shall have the authority to issue subpoenas, upon application of an attorney responsible for representing the Commonwealth in disciplinary matters before the board, for the purpose of investigating alleged violations of the disciplinary provisions administered by the board. The board shall have the power to subpoena witness, to administer oaths, to examine witnesses and to take such testimony or compel the production of such books, records, papers and documents as it may deem necessary or proper in, and pertinent to, any proceeding, investigation or hearing, held or had by it. Patient records may not be subpoenaed without consent of the patient or without order of a court of competent jurisdiction on a showing that the records are reasonably necessary for the conduct of the investigation. The court may impose such limitations on the scope of the subpoenas as are necessary to prevent unnecessary intrusion in patient confidential information. The board is authorized to apply to the Commonwealth Court to enforce its subpoenas.
