What information must be removed from a patient's record to de identify them?

To de-identify a patient's record, all personally identifiable information (PII) must be removed, including names, addresses, phone numbers, and email addresses. Additionally, unique identifiers such as Social Security numbers and medical record numbers should be excluded. Furthermore, any information that could potentially reveal the patient's identity, such as dates of service, geographic subdivisions smaller than a state, and specific details about the patient's condition, should also be omitted. This ensures that the data cannot be traced back to any individual patient.
