If the VA denied your disability claim because they claim it isn’t "service-connected," don't panic. Most veterans only know about direct service connection, but the law actually provides five distinct legal theories to connect your current health conditions to your military service. In this video, we break down the Alternative Theories of Service Connection using federal regulations (38 CFR) so you can figure out the exact strategy needed to win your appeal. Whether your service worsened a pre-existing condition, an official rating caused a new secondary illness, or you qualify under presumptive exposure rules, we cover the exact evidentiary benchmarks you must meet.
