The VA changed the way they rate tinnitus in 2025. It is no longer a stand alone condition, but viewed as a symptom of another primary condition. So, it usually has to be linked to a hearing loss diagnosis. FWIW, I just went through the C&P process and successfully got a 10% rating for tinnitus because it was connected with mild hearing loss, that incidentally had a 0% rating. You basically have to be deaf and on hearing aids to get any rating at all for hearing loss, but that is the way to get compensated for your tinnitus. You can amend your claim on that basis, if you think the extra 10% is worth the effort.
