When OWCP finds that an employee or his or her representative
refuses or obstructs a medical examination required by OWCP, the right
to COP is suspended until the refusal or obstruction ceases. COP already
paid or payable for the period of suspension is forfeited. If already
paid, the COP may be charged to annual or sick leave or considered an
overpayment of pay consistent with 5 U.S.C. 5584.
