ARV
Access Restriction
The ARV segment is used to communicate the requested/required type of access restrictions from system to system, at both the person/patient and the encounter/visit level.
The Access Restrictions segment (ARV) sent after the MSH acts as a manifest and declares the privacy and security classification (i.e the confidentiality level), the sensitivity (i.e. access restriction reason) and provides handling instructions (e.g. what the data can be used for, what must be done to protect it and what may not be done with the data). The segment is optional and can repeat.
