(c) When members who incur a disease or an injury during a period of training or duty under title 32, U.S.C. 503, 504, 505, or 502f are admitted to an Army medical treatment facility, and it appears that a finding of “not in line of duty” may be appropriate, a formal line of duty investigation should be promptly conducted, and a copy of the report furnished the treatment facility. If these findings result in a “not in line of duty” determination prior to the date the training is terminated, every effort should be made to assist the hospital concerned in disposing of the patient from the hospital by the date the training is terminated or as soon thereafter as he/she becomes transportable. Medical care furnished such member after the termination of the period of training is not authorized at Army expense unless the “not in line of duty” determination is ultimately reversed. The individual may be furnished medical care at Army expense from the date the training is terminated to the date the member receives notification of this action. Medical care received subsequent to the member's receipt of such notification is not authorized at Army expense. In the event a line of duty investigation has not been made by the date the training is terminated, every effort will be made to arrive at a determination as soon thereafter as possible.

(32 U.S.C. 318-320 and 502-505)
