| 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 cervical 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. 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 cervical 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 cervical spine greater than 30 degrees but not greater than 40 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. | Your forward flexion is greater than 30 degrees but not greater than 40 degrees, or your combined range of motion is greater than 170 degrees but not greater than 335 degrees, or you have muscle spasm or guarding that does not result in abnormal gait or spinal contour. |
|---|
What supports this level- Forward flexion 31-40 degrees
- Combined range of motion 171-335 degrees
- Muscle spasm or guarding without abnormal gait
|
| 20% | Forward flexion of the cervical spine greater than 15 degrees but not greater than 30 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. | Your forward flexion is greater than 15 degrees but not greater than 30 degrees, or your combined range of motion is 170 degrees or less, or you have muscle spasm severe enough to cause abnormal gait or spinal contour. |
|---|
What supports this level- Forward flexion 16-30 degrees
- Combined range of motion 170 degrees or less
- Muscle spasm causing abnormal gait or spinal contour
|
| 30% | Forward flexion of the cervical spine 15 degrees or less; or, favorable ankylosis of the entire cervical spine. | Your forward flexion is 15 degrees or less, or you have favorable ankylosis of your entire cervical spine. |
|---|
What supports this level- Forward flexion 15 degrees or less
- Favorable ankylosis of entire cervical spine
|
| 40% | Unfavorable ankylosis of the entire cervical spine. | You have unfavorable ankylosis of your entire cervical spine. |
|---|
What supports this level- Unfavorable ankylosis of entire cervical spine
- Neck fixed in flexion or extension
|
| 100% | Unfavorable ankylosis of the entire spine. | You have unfavorable ankylosis of your entire spine (cervical and thoracolumbar). |
|---|
What supports this level- Unfavorable ankylosis of the entire spine
