The HIPAA privacy rule sets forth policies to protect all individually identifiable health information that is held or transmitted.
When personally identifiable information is used in along with a physical or mental health or condition, health care, or one’s payment for that health care, it becomes Protected Health Information (PHI).
Individually Identifiable Information elements are protected by HIPAA Laws.
These are the 18 HIPAA Identifiers that are considered personally identifiable information and can be used to identify, contact, or locate a single person or can be used with other sources to identify a single individual.
These identifiers must be treated with special care.
