Your buddy got 70% for the "same" condition and you got 30%. That comparison is useless, and here is why.
It happens in every VFW hall and every online forum: "He got 70% for the same back condition and I only got 30%." I understand the frustration, but that comparison will lead you in the wrong direction every time.
Ratings are about evidence, not diagnosis
Two veterans with the "same" condition can have completely different files. Ratings under 38 CFR Part 4 are driven by measured severity, range of motion, frequency of flare-ups, functional loss, not by the name of the condition. His 70% reflects his evidence. Your 30% reflects yours.
Fix your file, not the comparison
Instead of asking why his number is higher, ask what his file has that yours does not: current measurements, a nexus opinion, documented flare-ups. Then build those into your own claim. The path to a higher rating runs through your evidence, not someone else's award letter.
The regulatory authority behind toxic-exposure claims lives in M21-1, Part IV, Subpart ii, Chapter 2, Section C (Service Connection for Disabilities Resulting from Exposure to Environmental Hazards). This section governs how raters develop and adjudicate toxic-exposure claims, including burn-pit, Agent Orange, contaminated-water, and radiation claims, and cross-references the PACT Act's conceded-exposure framework under 38 U.S.C. §1168 (TERA). When a C&P examiner renders a negative nexus opinion without addressing the documented exposure pathway, that opinion is inadequate under Barr v. Nicholson, and raters are required to return it for a supplemental opinion. Veterans who receive a denial after a cursory exam should cite the specific M21-1 development procedures the rater failed to follow.
