Anyone who has retired pursuant to the provisions of section 87.170 and has been reinstated pursuant to subsection 2 of section 87.130 who subsequently becomes disabled, as provided in section 87.200, shall receive a total benefit which is the higher of either the disability pension or the service pension.

Upon retirement for accidental disability on or after August 28, 2011, based on conditions of the heart, lungs, or cancer or based on permanent and total disability which will prevent the member from obtaining employment elsewhere, as determined by the board of trustees based on medical evidence presented by the retirement system’s physicians, a member shall receive, regardless of his or her number of years of creditable service, seventy-five percent of the earnable compensation then provided for the step in the range of salary for the title or rank held by such member at the time of such retirement.

Except as provided in subsection 3 of this section, upon retirement for accidental disability on or after August 28, 2011, the member may elect to receive an education allowance in an amount not to exceed the tuition for a state resident at the University of Missouri-St. Louis. The accidentally disabled member shall enroll in a college, university, community college, or vocational or technical school at the first opportunity after the accidentally disabled member was retired and shall receive such educational allowance in the form of reimbursement upon proof of payment to such institution. The education allowance described in this subsection shall cease when the accidentally disabled member ceases to be a full-time student, fails to provide proof of achievement of a grade point average of two on a four-point scale or the equivalent on another scale for each academic term, or if the accidentally disabled member is restored to active service as a firefighter, but in no event shall such education allowance be available for more than five years after the member is retired under section 87.200.
