VASRD 5241 · Musculoskeletal System
Surgical joining of two or more vertebrae, limiting spinal motion.
| Rating | Criteria |
|---|---|
| 100% | The entire spine — neck and back together — is fused rigid in a poor position, meeting VA's definition of unfavorable ankylosis. |
| 50% | The whole mid and lower back is fused rigid in a poor position, though the neck still moves. |
| 40% | The whole neck is fused rigid in a poor position, the lower back bends forward only 30 degrees or less, or the whole mid and lower back is fused in a neutral position. |
| 30% | The neck bends forward only 15 degrees or less, or the whole neck is fused in a neutral position. |
| 20% | Moderate loss of back or neck motion, or muscle spasm or guarding bad enough to change how you walk or hold your spine. |
| 10% | Mild loss of back or neck motion; or muscle spasm, guarding, or localized tenderness that does not change gait or posture; or a vertebral body that lost half its height or more in a fracture. |
Rated under the General Rating Formula for Diseases and Injuries of the Spine (38 CFR 4.71a) on the residual loss of motion, not on the surgery itself. A fused segment is ankylosis: under Note (5), fixation of a spinal segment in neutral position (zero degrees) is always favorable ankylosis, while unfavorable ankylosis means the segment is fixed in flexion or extension and produces one or more listed consequences such as difficulty walking because of a limited line of vision, restricted opening of the mouth and chewing, dyspnea or dysphagia, or neurologic symptoms due to nerve root stretching. Any associated objective neurologic abnormality — including, but not limited to, bowel or bladder impairment — is evaluated separately under an appropriate diagnostic code rather than raising the spine percentage.
