A physician must retain the basic information from each record destroyed: the patient’s name, birthdate, a dated list of diagnoses and treatments, and a record of drugs prescribed. A health care facility must retain the basic information from each record destroyed: the patient’s name, birthdate, dates of admission and discharge, names of attending physicians, diagnoses, major procedures performed, reports, and discharge summaries.
 
The provider must maintain the basic information for 25 years after the last entry. In the case of minor patients, basic information must be retained for 25 years past the minor’s 18th birthday.
