Hospitals: New Mexico requires hospitals retain records for a standard of ten (10) years after discharge. For minors, records must be retained until the patient reaches 21 years of age.
Physicians: Private practices must navigate existing Medicare laws and insurance mandates and add two (2) years to all requirements therein to meet state retention standards. This generally means at least ten (10) years from the date of the last treatment. Private practices must retain records for minor patients until the patient turns 21.
