The Board has denied the Veteran's claim for service connection for left ear hearing loss as there is no evidence of a current disability. The issue of an evaluation in excess of 10 percent for a back disability is remanded due to lack of recent VA examination.

The Board remands the issue of entitlement to service connection for a back disability due to a duty to assist error, specifically regarding VA's failure to provide the Veteran with a VA examination prior to the rating decision.

The appeal for a compensable rating for left ear hearing loss, service connection for right ear hearing loss, and bilateral vision condition was dismissed. Service connection for hypertension, congestive heart failure, and coronary artery disease was denied.

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 remands the claim for service connection of left ear hearing loss due to a pre-decisional duty to assist error, as an addendum opinion is necessary to address evidence of in-service hearing loss and convert audiometric testing results from ASA to ISO-ANSI standards.
