Intervertebral Disc Syndrome is rated by the U.S. Department of Veterans Affairs under DC 5243 of 38 CFR § 4.71a, DC 5243 across 10 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.

Overview

Intervertebral Disc Syndrome (IVDS), commonly called a herniated, ruptured, slipped, or bulging disc, is a condition in which the soft inner nucleus of an intervertebral disc protrudes through a tear in the tougher outer annulus, often compressing adjacent nerve roots or the spinal cord. It produces localized back or neck pain together with radiating symptoms such as numbness, tingling, weakness, or sciatica down the limb served by the affected nerve root, and can flare into acute episodes that limit motion and activity. IVDS most often affects the lumbosacral and cervical segments and is confirmed on MRI or CT, with electrodiagnostic studies (EMG/nerve conduction) used to characterize any associated nerve-root involvement.

Key Evidence

—Service treatment records showing injury or complaints

—Imaging (X-ray, MRI, CT)

—Range of motion measurements

—Flare-up documentation per Sharp v. Shulkin

—Buddy statements describing limitations

—Prescription history

—Physical therapy records

—Employment impact documentation

C&P Exam Tips

1Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.

2Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.

3Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.

4Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).

5If you use assistive devices (brace, cane), bring them.

6Describe daily activity impact: work, sleep, household tasks.
