Evidence Checklist: Intervertebral Disc Syndrome (IVDS)

Nexus opinion linking IVDS to service ("at least as likely as not")Critical

A medical opinion connecting your intervertebral disc disease to in-service injury, heavy lifting, or repetitive spinal stress during military duties.

Documentation of radiculopathy symptoms (radiation, paresthesia, weakness)

Records documenting nerve root involvement including radiating pain, numbness, tingling, weakness, or reflex changes in the extremities -- these may support additional separate ratings for radiculopathy.

Spinal range of motion measurements during and between flares

Examination documenting lumbar or cervical range of motion in degrees, including measurements taken during flare periods where possible to reflect true functional limitation.

Documentation of incapacitating episodes (frequency, duration, bed rest required)Critical

Medical records and personal logs documenting episodes requiring prescribed bed rest or hospitalization. VA rates IVDS under DC 5243 based on total weeks of incapacitating episodes per year -- this documentation drives the rating.

MRI of spine documenting disc herniation, bulge, or protrusionCritical

MRI findings confirming disc pathology including herniation, protrusion, extrusion, annular fissure, or foraminal/central stenosis contributing to nerve root or cord compression.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Back (Thoracolumbar Spine) ConditionsCritical

Standardized form capturing IVDS diagnosis, incapacitating episode history, spinal range of motion, and neurological findings.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
