Here is the rating criteria that will most likely be applied to your condition:
General Rating Formula for Diseases and Injuries of the Spine
(For diagnostic codes 5235 to 5243 unless 5243 is evaluated under the Formula for Rating
Intervertebral Disc Syndrome Based on Incapacitating Episodes):
With or without symptoms such as pain (whether or not it radiates), stiffness, or aching in the area of the spine affected by residuals of injury or disease
Unfavorable ankylosis of the entire spine............................................................... 100
Unfavorable ankylosis of the entire thoracolumbar spine......................................... 50
Unfavorable ankylosis of the entire cervical spine; or, forward flexion
of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of
the entire thoracolumbar spine............................................................................. 40
Forward flexion of the cervical spine 15 degrees or less; or, favorable
ankylosis of the entire cervical spine.................................................................... 30
Forward flexion of the thoracolumbar spine greater than 30 degrees but not
greater than 60 degrees; or, forward flexion of the cervical spine greater
than 15 degrees but not greater than 30 degrees; or, the combined range of
motion of the thoracolumbar spine not greater than 120 degrees; or, the
combined range of motion of the cervical spine not greater than 170 degrees;
or, muscle spasm or guarding severe enough to result in an abnormal gait
or abnormal spinal contour such as scoliosis, reversed lordosis, or
abnormal kyphosis................................................................................................ 20
Forward flexion of the thoracolumbar spine greater than 60 degrees but not
greater than 85 degrees; or, forward flexion of the cervical spine greater than
30 degrees but not greater than 40 degrees; or, combined range of motion of
the thoracolumbar spine greater than 120 degrees but not greater than 235
degrees; or, combined range of motion of the cervical spine greater than
170 degrees but not greater than 335 degrees; or, muscle spasm, guarding,
or localized tenderness not resulting in abnormal gait or abnormal spinal
contour; or, vertebral body fracture with loss of 50 percent or more of the
height.................................................................................................................... 10
Much will depend on your Range of Motion.
