If an employee refuses to submit to or in any way obstructs an
examination required by OWCP, his or her right to compensation under the
FECA is suspended until such refusal or obstruction stops. The action of
the employee's representative is considered to be the action of the
employee for purposes of this section. The employee will forfeit
compensation otherwise paid or payable under the FECA for the period of
the refusal or obstruction, and any compensation already paid for that
period will be declared an overpayment and will be subject to recovery
pursuant to 5 U.S.C. 8129.
