Most VA claims are not denied because the veteran does not qualify. They are denied because something is missing. The good news is that the same handful of mistakes come up again and again, which means most of them are avoidable. Here are seven that quietly weaken claims, and how to fix each one before you file.
The nexus is the medical link between your condition and your service, or between a secondary condition and a service-connected one. It is the single most common gap. A diagnosis alone does not connect the condition to service; a provider has to explain that it is at least as likely as not related. Learn the framework in how to prove a condition is service-connected, and bring your doctor the free Nexus Letter Template.
VA rates conditions you currently have. A history of symptoms is not enough without a current, documented diagnosis from a provider. If you have symptoms but no formal diagnosis, getting evaluated is often the first step, not filing.
VA rates many conditions on how they affect you during a flare-up or a bad stretch, not on your best day. Veterans routinely undersell their symptoms at the C&P exam and in their statements, and get rated on the minimized version. Describe your worst days honestly. See what to expect at your C&P exam.
Even with a service connection, the rating depends on documented severity: range-of-motion measurements, test results, symptom frequency, and how the condition limits your work and daily life. Gather the evidence that matches how VA rates your specific condition. The ratings overview explains how severity becomes a percentage.
One service-connected condition often causes others. PTSD is linked to sleep apnea and GERD; back conditions can cause radiculopathy; medications can cause their own issues. Veterans routinely leave money on the table by claiming only the primary. Explore the links with the free Secondary Conditions Mapper and read how secondary conditions work.
Your effective date sets how far back your back pay goes. Filing an Intent to File locks in a date while you gather evidence, and filing a supplemental claim within one year of a denial protects the original date. Miss these windows and you can lose months of back pay.
A claim scattered across loose records, half-finished statements, and forgotten questions is hard for a reviewer, and hard for the VSO helping you. Organizing your conditions, evidence, and questions in one place before you file, or before you meet a representative, is one of the simplest ways to strengthen a claim.
