The veteran's claim for a disability rating in excess of 40 percent for degenerative disc disease with lumbosacral strain is being remanded to obtain additional evidence.

The Board granted a 40 percent evaluation for sciatic nerve radiculopathy of the right and left lower extremities, a 30 percent evaluation for femoral nerve radiculopathy of the right and left lower extremities, and a total disability rating based on individual unemployability (TDIU), but denied an increased evaluation in excess of 40 percent for spinal stenosis and lumbar intervertebral disc syndrome.

The Board granted initial ratings of 40 percent for degenerative disc disease and 20 percent for right and left lower extremity radiculopathies, but denied higher ratings. Other claims were either granted with non-compensable ratings or denied.

The Board granted service connection for obstructive sleep apnea, effective from the date of the February 2025 rating decision.

The Board remands the claim for a medical examination to determine if the Veteran's current neck strain is related to his in-service activities.
