The Veteran's cervical spine disability was granted an initial rating of 20 percent, but no higher. The low back disability was granted a 40 percent rating prior to July 21, 2023, and the claim for a rating in excess of 40 percent from that date was denied.

The Board remands the claims for service connection for various disabilities to the AOJ for further development and consideration of evidence not previously considered.

The Board granted a 20 percent disability rating for left and right lower extremity radiculopathy from April 3, 2023 onward, but denied higher ratings prior to that date. Service connection was also granted for alcohol use disorder as secondary to PTSD with traumatic brain injury.

The Board denied service connection for the veteran's claimed conditions, including right shoulder arthritis, left shoulder arthritis, right hip condition, left hip condition, low back disability, and bilateral lower extremity radiculopathy, as there was no evidence of in-service injury or illness related to these conditions.

The Board dismissed the appeals for service connection for a bilateral knee disability, bilateral upper and lower extremity peripheral neuropathy, lumbar spine disability, cervical spine disability, and chronic pain syndrome due to untimely notices of disagreement.
