The Board denied the Veteran's claims for service connection for left ankle lateral collateral ligament sprain, osteoarthritis and for an acquired psychiatric disorder to include PTSD. The decision found that there was no evidence of herbicide exposure during service and that the current disabilities were not related to service.

The appeal is remanded to correct pre-decisional duty to assist errors, including the failure to obtain relevant treatment records and provide adequate VA examinations.

The Board denied service connection for multiple conditions, including rheumatoid arthritis, right hip degenerative joint disease and rheumatoid arthritis with acetabular cyst status post right total hip replacement, osteoarthritis, psoriatic arthritis, hypertension, prostate cancer, diabetes mellitus type II, fever sores, and a compromised immune system, as the evidence did not support a finding of service connection for any of these conditions.

The Board denied the veteran's claims for increased ratings for various service-connected conditions, finding that the evidence did not support a higher rating under applicable criteria.

The Board granted service connection for sleep apnea, left shoulder bicipital tendon tear, hypogonadism, erectile dysfunction, and left carpal tunnel syndrome. The claims for increased ratings for lumbar spondylosis with facet arthropathy and lumbosacral strain, right hip strain with osteoarthritis, other specified trauma and stressor related disorder, left and right ankle lateral collateral ligament sprain, right shoulder rotator cuff tear, left knee patellofemoral pain syndrome, right knee patellofemoral pain syndrome (to include iliotibial band syndrome), and chronic right wrist sprain were denied. The Board also granted an effective date of July 7, 2023 for the award of increased ratings.
