Neb. Rev. Stat. §§ 48-134
After an employee has given notice of an injury, as provided in section 48-133, and from time to time thereafter during the continuance of his or her disability, he or she shall, if so requested by the employer or the insurance company carrying such risk, submit himself or herself to an examination by a physician or surgeon legally authorized to practice medicine under the laws of the state in which he or she practices, furnished and paid for by the employer, or the insurance company carrying such risk, as the case may be. The employee shall have the right to have a physician provided and paid for by himself or herself present at the examination. The unreasonable refusal of the employee to submit to such examination shall deprive him or her of the right to compensation under the Nebraska Workers' Compensation Act during the continuance of such refusal, and the period of such refusal shall be deducted from the period during which compensation would otherwise be payable.
