Nearly all back and neck conditions, strains, degenerative disc disease, stenosis, fusion, fracture, are rated under this same General Rating Formula for Diseases and Injuries of the Spine, based primarily on range of motion and ankylosis (fusion).
The cervical spine (neck) and thoracolumbar spine (mid and lower back) are rated SEPARATELY, as two independent ratings, not combined into one. A very common mistake is claiming only "back pain" generally, or claiming only one region, when both are affected and each deserves its own rating. Another common miss: associated nerve symptoms (radiating pain, numbness, bowel/bladder impairment) are rated separately under peripheral nerve diagnostic codes, and combined with the spine rating, they are not folded into the spine percentage itself.
| Rating | Criteria |
|---|---|
| 100% | Unfavorable ankylosis of the entire spine |
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine |
| 40% | Unfavorable ankylosis of the entire cervical spine; or forward flexion of the thoracolumbar spine 30° or less; or favorable ankylosis of the entire thoracolumbar spine |
| 30% | Forward flexion of the cervical spine 15° or less; or favorable ankylosis of the entire cervical spine |
| 20% | Forward flexion of the thoracolumbar spine greater than 30° but not greater than 60°; or combined range of motion of the thoracolumbar spine not greater than 120°; or combined range of motion of the cervical spine not greater than 170°; or muscle spasm, guarding, or localized tenderness resulting in abnormal gait or abnormal spinal contour (scoliosis, reversed lordosis, or abnormal kyphosis) |
| 10% | Forward flexion of the thoracolumbar spine greater than 60° but not greater than 85°; or combined range of motion of the thoracolumbar spine greater than 120° but not greater than 235°; or combined range of motion of the cervical spine greater than 170° but not greater than 335°; or muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour; or vertebral body fracture with loss of 50% or more of height |
