I have worked for the same construction company(steel erection) for 30 years. I was injured on the job, and have had surgery. I'm currently in pain management. I have reached MMI, and have a 20% impairment to the spine (lumbar). I'm a little confused about the impairment rating. I have done a little research, and it seems that the max impairment to that area of the spine is 28%?? Is this correct?? How does this relate to a disability rating? WC has not offered a settlement yet, and I have no idea what to expect. (and I do not have a lawyer)The surgeon told me that I'm done with construction work. I am not to do any heavy lifting, very little bending, and no repetative type work. He told me that he doesn't even want me mowing my lawn. The company I have worked for is closing , and I'm not sure what to do. I imagine my employment options are severely limited now. I would appreciate any advice/opinions you guys might have.
