What does 'no nexus' mean on a VA denial?

Details

• When the evidence is in approximate balance, the benefit of the doubt goes to the claimant (38 CFR § 3.102).
• An opinion that states a conclusion without reasoning carries no weight (Nieves-Rodriguez v. Peake).
• If the needed evidence is already in the file and was not addressed, Higher-Level Review reviews that same record.
• If a new opinion is required, a Supplemental Claim under 38 CFR § 3.2501 is the lane that accepts it.
