Extension: area

FHIR Infrastructure Work Group

Maturity Level: 1

Informative

Use Context: Any

URL for this extension:

http://hl7.org/fhir/StructureDefinition/contactpoint-area

Status: draft. Extension maintained by: Health Level Seven, Inc. - FHIR Core WG

The area/zone/city code that, in some areas, may be omitted when dialing locally within the zone. This extension is used when a system wishes to designate specific parts of a phone number (and potentially place constraints on which components must be present and how they're filled in).

Comment:

The ContactPoint.value element SHOULD still be populated even if the extension is present.

Context of Use: Use on Element ID ContactPoint
