I'm also a veteran with service connected disabilities including hearing loss and tinnitus among other things. I think your "go to" is your Veterans Service Officer (VSO). These people are employed to help veterans get help. They are not VA employees and do not answer to VA. So I advise you to contact your VSO.

Also your primary care provider should be able to help you get the right answer too. You should be able to contact your PCP via "Secure Messaging" on the va.gov website (after signing up).

VA does consider tinnitus a compensable disability but only up to 10%. Depression is associated with hearing loss in 40% of cases according to what I have read. Tinnitus is also associated with hearing loss. My understanding is that hearing loss is not necessarily causative but is strongly associated with both depression and tinnitus. But those are only my experiences. Contact your VSO and PCP for better information.
