5 CFR § 339.304 - Payment for examination.
(a) An agency must pay for all medical and/or psychological and/or psychiatric examinations required or offered by the agency under this subpart, whether conducted by the agency's physician or medical review officer, an independent medical evaluation specialist (e.g., occupational audiologist) identified by the agency, or a licensed physician or practitioner chosen by the applicant or employee. This includes special evaluations or diagnostic procedures required by an agency.
(b) Following conclusion of the initial medical, psychological, and/or psychiatric examination, the agency physician or medical review officer will render a final medical determination. In certain final medical ineligibility determinations, the agency physician or medical review officer may reference supplemental medical examination, testing or documentation, which the applicant or employee may submit to the agency for consideration and further review relative to potential medical eligibility. Under these circumstances, the applicant or employee is responsible for payment of this further examination, testing and documentation.
(c) An applicant or employee must pay to obtain all relevant medical documentation from his or her private licensed physician or required practitioners in instances where no medical examination is required or offered by the agency, but where the agency requests the applicant or employee to provide medical documentation relative to an identified medical or physical condition in question or where the agency needs medical documentation to render an informed management decision.
(d) An applicant or employee must pay for a medical examination conducted by his or her private licensed physician or practitioner where the purpose of the examination is to secure a change sought by an applicant (e.g., new employment) or by an employee (e.g., a request for change in duty status, reasonable accommodation, and/or job modification).
