19 Miss. Code. R. 7-15.07
Any first responder receiving disability benefits may be required by the state, county, municipality or fire protection district for whom he or she works to have his or her condition reevaluated to determine if that first responder has regained the ability to perform the duties of a first responder. If that reevaluation indicates that the first responder has regained the ability to perform the duties of a first responder, then the monthly disability benefits shall cease on the last day of the month the reevaluation was conducted. If there is no reevaluation performed, but the first responder's treating physician determines that the first responder is again able to perform the duties of a first responder, then the disability benefits shall cease on the last day of the month that the physician made the determination.
