  "description": "Sometimes a referral needs to communicate where the patient is at the time of the referral (e.g., in Ward X of Hospital Y), which may be different from the patient's home address. To communicate this, use this extension, which references a Location resource.  Present location can be nested using Location.partOf to communicate locations with multiple levels, e.g., Location.partOf > Location for WardX > HospitalY.",
