Hospitals: Maine state codes require hospitals keep records for seven (7) years, or in the case of minor patients, until six (6) years after the patient turns 18.
Physicians: Maine state codes also mandate permanent retention for certain patient data, including x-ray reports. Maine does not offer specific guidance for private practices. Consult LINK for more on what to do when your state offers limited legal guidelines for records retention policy.
