GBArmy, while I appreciate your interest, neither one of those codes, 7800 and 7901 pertain to me. I have TWO pending claims. The first, AO tongue cancer with residuals, (including hypothyroidism), on appeal remand from the Veteran's court, with an attorney this time. Also, a supplemental claim for hypothyroidism, since the new law made it a presumptive AO Vietnam disease, and should be a slam dunk. In the original one, I was treated for the cancer, but I'm asking for 100% because VA Dental will not do the extensive work I need without it. I have a C&P coming up and hope for at least enough to bump my 60% to 100% between the two claims. My diagnostic code is 7903.
