I have a question about the Subsequent Injuries Fund, My DOI was May of 03, I have had four surgeries on my knees and right foot, I am currently waiting to have a total right knee replacement around Sept. I have not been given a PD rating. In 1996 I was awarded a Total Disability through SSDI for different injuries, I eventually forced myself back to work, until I had my accident at work. I have heard that if your Workers Compensation injury is rated at 35 percent or higher, that I could possibly combine my previous disability with the Workers Comp injury and recieve a higher award. Can anyone give me more info on the subsequent injuries fund, and what I need to do in the event that I am rated at or over 35 percent?
