I was retired on disability on September 01, 2010. I figured I would just receive a check every month and go on with my life. Low and behold I receive a copy of my doctors disability rating letter and I have no idea what it means or what I should do. The letter states, " I am giving him a 10% permanent partial impairment of his involved lower right extremity". This letter was dated a month after Prince Georges County retired me. I need to know what my entitlements are , if any, and if I need to act on the new information in any way.
