The Veteran's left shoulder residuals and degenerative arthritis are rated at 20 percent from February 27, 2013. The Veteran's multilevel degenerative arthritis of the lumbar spine is rated at 10 percent from April 23, 2015.

The Veteran's claim for an earlier effective date for the award of TDIU was denied as there were no unadjudicated claims for TDIU prior to April 28, 2023. The current effective date is the earliest possible based on the schedular criteria.

The Veteran's claims for increased disability ratings remain on appeal. The RO must consider all of the evidence received since the issuance of the May 2015 supplemental statement of the case and issue a rating decision to implement the grant of an increased disability evaluation of 10 percent for the service-connected multi-level degenerative arthritis of the lumbar spine and a 20 percent disability for the anterior reconstruction and arthroscopic surgery of the left shoulder, effective April 23, 2015.

The Board denied the veteran's claims for increased ratings for his service-connected lumbar myositis, psychoneurosis and conversion hysteria, residuals of shrapnel wounds of the left thigh and pelvis with retained foreign bodies and scars, and residuals of shell fragment wounds of the right thigh and left leg. The veteran was also denied entitlement to a total disability rating based on individual unemployability due to service-connected disabilities.

The Board denied the Veteran's claim for an initial evaluation in excess of 10 percent for his service-connected coronary artery disease, finding that the evidence did not support a higher rating based on the severity of his condition.
