HNS Policy  

The patient health care record, including associated relevant and/or supporting documents, must be maintained in a safe and secure location. HNS providers must retain complete patient health care records (including all EOBs) for a minimum of 10 years from the last date of service OR, if the patient is a minor, for 10 years after the minor patient reaches age 19.  Once the patient reaches 19 and is still under care, the provider should retain the patient health care record for 10 years from the last date of service.
