Mistake #1: Not claiming everything
Veterans often leave conditions off their claim thinking they're minor or won't be approved. Claim every condition that bothers you. A 10% rating pays $180.42 a month tax-free in 2026. Multiple "small" ratings combine to create a significant total.
Mistake #2: No current diagnosis
"My back hurts" is a symptom, not a diagnosis. The VA requires a medical diagnosis from a qualified provider. Get diagnosed before you file, don't rely on the C&P exam to diagnose you.
Mistake #3: Filing without a nexus
For non-presumptive conditions, a common reason for denial is no evidence linking the condition to service. If it's been more than a year since separation, get a nexus letter before filing.
Mistake #4: Being tough at the C&P exam
Military culture teaches you to push through pain. The C&P exam is not the place for that. Describe your worst days honestly. "I'm fine" on your exam report translates to a low or zero rating.
Mistake #5: Missing the C&P exam
Miss your C&P exam = likely denial. If you can't make it, call to reschedule immediately. If you already missed one, contact the VA right away to request a new one.
Mistake #6: Not filing an Intent to File first
Your effective date is set by when you submit the ITF or claim, not by when you could have. An ITF takes little time and costs nothing.
Mistake #7: Submitting incomplete records
Don't assume the VA has your records. Request your own copies of STRs, VA records, and private records. Upload everything with your claim.
Mistake #8: Ignoring secondary conditions
If you have service-connected PTSD and now have sleep apnea, that sleep apnea may be secondary to PTSD. A secondary condition can be rated and paid on its own.
Mistake #9: Using the wrong claim type
Filing a new claim when you should file for increase, or vice versa, can delay your case by months. Understand the difference:
- New claim: First time claiming this condition
- Increase: Already service-connected, condition has worsened
- Secondary: New condition caused by an existing service-connected condition
- Supplemental: Previously denied, filing again with new evidence
Mistake #10: Giving up after a denial
A denial letter states the reason for the decision. Get the evidence it says was missing and file a supplemental claim, or choose another review lane (see the appeals guide).
