(a) If health plan coverage for the employee or a dependent was terminated by reason of service in the uniformed services, that coverage must be reinstated upon reemployment. An exclusion or waiting period may not be imposed in connection with the reinstatement of coverage upon reemployment, if an exclusion or waiting period would not have been imposed had coverage not been terminated by reason of such service.

(b) USERRA permits a health plan to impose an exclusion or waiting period as to illnesses or injuries determined by the Secretary of Veterans Affairs to have been incurred in, or aggravated during, performance of service in the uniformed services. The determination that the employee's illness or injury was incurred in, or aggravated during, the performance of service may only be made by the Secretary of Veterans Affairs or his or her representative. Other coverage, for injuries or illnesses that are not service-related (or for the employee's dependents, if he or she has dependent coverage), must be reinstated subject to paragraph (a) of this section.
