(a) When an employee sustains a work-related traumatic injury that requires medical examination, medical treatment, or both, the employer shall authorize such examination and/or treatment by issuing a Form CA-16. This form may be used for occupational disease or illness only if the employer has obtained prior permission from OWCP.
(b) The employer shall issue Form CA-16 within four hours of the claimed injury. If the employer gives verbal authorization for such care, he or she should issue a Form CA-16 within 48 hours. The employer is not required to issue a Form CA-16 more than one week after the occurrence of the claimed injury. The employer may not authorize examination or medical or other treatment in any case that OWCP has disallowed.
