(1) For compensation and pension examinations. A compensation and pension examination shall be performed for any veteran who is directed to have such an examination by VA.
(2) For adjunct treatment. Subject to the provisions of §§ 17.36 through 17.38, medical services on an ambulatory or outpatient basis shall be provided to veteans for an adjunct nonservice-connected condition associated with and held to be aggravating a disability from a disease or injury adjudicated as being service-connected.
(b) The term “shall furnish” in this section and 38 U.S.C. 1710(a)(1) and (a)(2) means that, if the veteran is in immediate need of outpatient medical services, VA shall furnish care at the VA facility where the veteran applies.
