Cervical Spondylosis is rated by the U.S. Department of Veterans Affairs under DC 5242 of 38 CFR § 4.71a, DC 5242 across 6 severity tiers (10% / 20% / 30% / 40% / 50%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Cervical spondylosis is age-related or wear-and-tow degenerative change of the cervical spine (neck), encompassing intervertebral disc desiccation and narrowing, osteophyte (bone spur) formation, facet-joint arthritis, and ligament thickening. It commonly produces neck pain and stiffness, reduced range of motion, and headaches, and when degenerative spurs or disc material narrow the spinal canal or nerve-root foramina it can cause cervical radiculopathy (arm pain, numbness, weakness) or, in advanced cases, cervical myelopathy. For VA purposes it is rated as degenerative arthritis / degenerative disc disease of the spine under Diagnostic Code 5242, primarily on the basis of limitation of cervical motion and ankylosis.
