“Go-to-Guidance” is the short name for HIPAA Administrative Simplification Guidance Letters. These Guidance Letters include important guidance about NSG’s interpretation of the HIPAA Administrative Simplification laws and regulations, and current thinking on how to apply these. Guidance Letters do not include any new mandates, requirements or prohibitions, and are not legally binding upon covered entities. Although Guidance Letters themselves are not legally binding, they may refer to statute and regulation which is legally binding. Guidance Letters do not supersede policy found in statute or regulation.
