| 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. | Cervical disc herniation with nerve root involvement is confirmed on imaging and service connected, but cervical forward flexion and combined range of motion fall inside the normal ranges the General Rating Formula sets, there is no muscle spasm, guarding or localized tenderness, and no physician-prescribed bed rest is on record. 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- MRI showing cervical disc herniation with nerve root compression or irritation
- Cervical forward flexion and combined range of motion measured and recorded, even when normal
- Examination finding no muscle spasm, guarding, or localized tenderness
- Every future episode of prescribed bed rest documented by the prescribing physician

Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes: With incapacitating episodes having a total duration of at least one week but less than 2 weeks during the past 12 months. | You have cervical IVDS with forward flexion of the cervical spine greater than 30 degrees but not greater than 40 degrees, or combined range of motion greater than 170 degrees but not greater than 335 degrees, or muscle spasm or guarding not resulting in abnormal gait or spinal contour. Alternatively, you have incapacitating episodes having a total duration of at least one week but less than 2 weeks during the past 12 months. |
|---|
What supports this level- Cervical spine forward flexion 31-40 degrees
- Combined ROM of cervical spine 171-335 degrees
- MRI showing cervical disc herniation or bulge
- Muscle spasm or guarding on examination
|
| 20% | General Rating Formula for Diseases and Injuries of the Spine: 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. Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes: With incapacitating episodes having a total duration of at least 2 weeks but less than 4 weeks during the past 12 months. | You have cervical IVDS with forward flexion of the cervical spine greater than 15 degrees but not greater than 30 degrees, or combined range of motion not greater than 170 degrees, or muscle spasm or guarding severe enough to result in abnormal gait or abnormal spinal contour. Alternatively, you have incapacitating episodes having a total duration of at least 2 weeks but less than 4 weeks during the past 12 months. |
|---|
What supports this level- Cervical spine forward flexion 16-30 degrees
- Combined ROM not greater than 170 degrees
- Abnormal gait or spinal contour from muscle spasm
- Incapacitating episodes totaling 2-4 weeks per year
- Doctor-prescribed bed rest documented
|
| 30% | General Rating Formula for Diseases and Injuries of the Spine: Forward flexion of the cervical spine 15 degrees or less; or, favorable ankylosis of the entire cervical spine. | You have cervical IVDS with forward flexion of the cervical spine limited to 15 degrees or less, or favorable ankylosis of the entire cervical spine. |
|---|
What supports this level- Cervical spine forward flexion 15 degrees or less
- Favorable ankylosis of the cervical spine
- Significant disc herniation on MRI
- Severe limitation of all cervical motions
|
| 40% | General Rating Formula for Diseases and Injuries of the Spine: 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. Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes: With incapacitating episodes having a total duration of at least 4 weeks but less than 6 weeks during the past 12 months. | You have cervical IVDS with unfavorable ankylosis of the entire cervical spine, or incapacitating episodes having a total duration of at least 4 weeks but less than 6 weeks during the past 12 months. |
|---|
What supports this level- Unfavorable ankylosis of the entire cervical spine
- Incapacitating episodes totaling 4-6 weeks per year
- Cervical spine fusion or severe multilevel disease
- Significant radiculopathy symptoms
|
| 60% | Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes: With incapacitating episodes having a total duration of at least 6 weeks during the past 12 months. Note (1): For purposes of evaluations under diagnostic code 5243, an incapacitating episode is a period of acute signs and symptoms due to intervertebral disc syndrome that requires bed rest prescribed by a physician and treatment by a physician. | You have cervical IVDS with incapacitating episodes having a total duration of at least 6 weeks during the past 12 months. |
|---|
What supports this level- Incapacitating episodes totaling 6 or more weeks per year
- Doctor-prescribed bed rest for each episode documented
- Severe multilevel cervical disc disease on MRI
- Failed conservative treatment including physical therapy
- Surgical intervention history or recommendation
|
| 100% | General Rating Formula for Diseases and Injuries of the Spine: Unfavorable ankylosis of the entire spine. Note (6): Separately evaluate disability of the thoracolumbar and cervical spine segments, except when there is unfavorable ankylosis of both segments, which will be rated as a single disability. | Your entire spine — cervical and thoracolumbar together — is fixed in unfavorable ankylosis. The General Rating Formula pays 100 percent for this, and it is the only 100 percent rung any spine diagnostic code prints. Note (6) to the formula says the cervical and thoracolumbar segments are rated separately EXCEPT when both are unfavorably ankylosed, in which case they are rated as a single disability at this level. |
|---|
What supports this level- Unfavorable ankylosis of the entire spine documented on examination
- Imaging showing fusion of both the cervical and thoracolumbar segments
- Spine fixed in flexion or extension with one or more of the Note (5) consequences (difficulty walking from a limited line of vision, restricted mouth opening and chewing, breathing limited to diaphragmatic respiration, gastrointestinal symptoms from costal-margin pressure, dyspnea or dysphagia, atlantoaxial or cervical subluxation or dislocation, or neurologic symptoms from nerve root stretching)
- Both spine segments evaluated in the same examination
