When a beneficiary either pleads guilty to or is found guilty on
either Federal or State criminal charges of defrauding the Federal
Government in connection with a claim for benefits, the beneficiary's
entitlement to any further compensation benefits will terminate
effective the date either the guilty plea is accepted or a verdict of
guilty is returned after trial, for any injury occurring on or before
the date of such guilty plea or verdict. Termination of entitlement
under this section is not affected by any subsequent change in or
recurrence of the beneficiary's medical condition.
