(1) "Branch office" means a location or site, identified in the application or endorsement thereto, from which a home health agency provides services within a portion of the total geographic area served by the parent agency and which is part of the home health agency and is located sufficiently close to share administration, supervision, and services in a manner that renders it unnecessary for the branch independently to meet the requirements of this article.

(3) "Home health services" means those items and services furnished to an individual according to a written plan of treatment signed by the patient's physician, by a home health agency, or by others under arrangement with the home health agency, on a visit or hourly basis, in a place of temporary or permanent residence used as the individual's home, as follows:

(A) Part-time or intermittent skilled nursing care as ordered by a physician and provided by or under the supervision of a registered nurse and at least one other service listed in subparagraphs (B) through (D) of this paragraph;

(9) "Registered nurse" means an individual who is currently licensed as a registered professional nurse in this state.

(10) "Subunit" means a semiautonomous organization which serves patients in a geographic area different from that of the parent agency and which, by virtue of the distance between it and the parent agency, is judged incapable of sharing administration, supervision, and services on a daily basis with the parent agency and must, therefore, independently meet the licensing requirements for a home health agency and shall be separately licensed.
