The waiver process established in regulation pursuant to paragraph (c) of subdivision three of this section shall provide that a practitioner prescribing under a waiver must notify the department in writing promptly upon gaining the capability to use electronic prescribing, and that a waiver shall terminate within a specified period of time after the practitioner gains such capability. * 7. Notwithstanding any other provision of this section or any other law to the contrary, a practitioner shall not be required to issue prescriptions electronically if he or she certifies to the department, in a manner specified by the department, that he or she will not issue more than twenty-five prescriptions during a twelve month period. Prescriptions in both oral and written form for both controlled substances and non-controlled substances shall be included in determining whether the practitioner will reach the limit of twenty-five prescriptions.
