| 0% | § 4.31 Zero percent evaluations. In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met. | The thoracic spine strain is diagnosed and service connected, but forward flexion and combined range of motion fall inside the normal ranges the General Rating Formula sets, and there is no muscle spasm, guarding, or localized tenderness. The lowest compensable rung on this ladder is 10 percent. A zero percent rating pays nothing now, but it establishes service connection and fixes the effective date any later increase runs from. |
|---|
What supports this level- Diagnosis of thoracic spine strain in the treatment record
- Forward flexion and combined range of motion measured and recorded, even when normal
- Examination finding no muscle spasm, guarding, or localized tenderness
- Range of motion re-measured during a flare-up, which is when it is most likely to be compensable
|
| 10% | Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees; or, combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees; or, muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour. | Your forward flexion of the thoracolumbar spine is greater than 60 degrees but not greater than 85 degrees, or your combined range of motion is greater than 120 degrees but not greater than 235 degrees, or you have muscle spasm or guarding not resulting in an abnormal gait. |
|---|
What supports this level- Forward flexion of thoracolumbar spine 61-85 degrees
- Combined range of motion 121-235 degrees
- Muscle spasm or guarding documented
- Pain on motion of the thoracic spine
|
| 20% | Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees; or, the combined range of motion of the thoracolumbar spine not greater than 120 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. | Your forward flexion of the thoracolumbar spine is greater than 30 degrees but not greater than 60 degrees, or you have muscle spasm severe enough to cause an abnormal gait or abnormal spinal contour. |
|---|
What supports this level- Forward flexion of thoracolumbar spine 31-60 degrees
- Combined range of motion 120 degrees or less
- Muscle spasm causing abnormal gait or spinal contour
- Imaging showing thoracic spine changes
|
| 40% | Forward flexion of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of the entire thoracolumbar spine. | Your forward flexion of the thoracolumbar spine is 30 degrees or less, or you have favorable ankylosis of the entire thoracolumbar spine. |
|---|
What supports this level- Forward flexion of thoracolumbar spine 30 degrees or less
- Favorable ankylosis of entire thoracolumbar spine
- Severe limitation in all planes of motion
- Significant functional impairment
|
| 50% | Unfavorable ankylosis of the entire thoracolumbar spine. | You have unfavorable ankylosis of the entire thoracolumbar spine. Your thoracolumbar spine is fixed in an abnormal position. |
|---|
What supports this level- Unfavorable ankylosis of entire thoracolumbar spine
- Spine fixed in abnormal position
- Total inability to bend the trunk
- Severe impact on daily activities
|
| 100% | Unfavorable ankylosis of the entire spine. | You have unfavorable ankylosis of the entire spine. Both your cervical and thoracolumbar spine are fixed in an abnormal position. |
|---|
What supports this level- Unfavorable ankylosis of entire spine
- Entire spine fixed in abnormal position
- Total inability to move the spine
- Severe impact on all daily activities
