A medical prescription in Mexico must show the number of the doctor’s cédula profesional, the professional license. Guidelines published in the official gazette in October 2025 list among the required data the “Número de Cédula Profesional o autorización provisional para ejercer como pasante” (number of the professional license, or provisional authorization to practice as an intern).
Under the General Health Law, a doctor who performs specialized surgery must hold a “Cédula de especialista legalmente expedida” (specialist’s license legally issued) and a current specialist’s certificate.
