I am serviced connected for ankylosing spondylitis back in 1985. I had a C&P exam on 7-7-19 since I am asking for an increase in my cervical, thoracic, and lumbosacral ratings. After speaking with the DAV to find out progress and info on my exam, the Rep. noted sort of what I expected. Radiculopathy was noted and ROM was 0-15 for cervical, and 0-25 for back. I am currently rated as Cervical 30%, Thoracic 10%, and Lumbosacral 40%. The main question that I have is relating to the thoracic 10% and lumbosacral 40%. I am confused on these two. Is Lumbosacral separate from the thoracic/others ? Since my back ROM is at 0-25, does this mean that my thoracic might increase from the 10% to a higher rating ? I am confused how they break down my ratings from cervical at 30%, Thoracic at 10%, and Lumbosacral at 40%. Did the VA make changes to the names of the spine regions after I was rated and how they would rate each one?....because I don't see Thoracic as a region now. I only see cervical and thoracolumbar. I'm not sure how they would rate/increase me...totally confused. Also, with the radiculopathy, is this something that they will rate also ? I am currently at 90% total combined for all my disabilities. I hope this helps for someone to give me advice/answers.
