Claimed GAD, but diagnosed PTSD on C&P

Your correct next step is to file a Supplemental Claim (VA Form 20-0995) with new and relevant evidence, as this allows you to directly address the diagnosis discrepancy and introduce the C&P exam as evidence, whereas a Higher-Level Review (HLR) is generally for arguing based on the existing record. The VA has a duty to maximize benefits under 38 CFR 3.303(a), which requires evaluating all evidence of record and considering all possible diagnoses; the denial for GAD while a PTSD diagnosis exists from a VA examination is a classic "inferred issue" error. You must formally claim PTSD, as it is a distinct diagnosis with different service-connection requirements (e.g., a verifiable stressor under 38 CFR 3.304(f)). In your Supplemental Claim, explicitly state you are claiming service connection for PTSD, cite the prior C&P examination that provided the diagnosis as new evidence, and submit a statement explaining that the examiner diagnosed PTSD in lieu of GAD. The VA must then adjudicate the claim for PTSD, rated under Diagnostic Code 9411 (or 9421 for chronic adjustment disorder) per 38 CFR 4.130. Case law like *Savage v. Shinseki* supports that the VA cannot ignore a diagnosis provided by its own examiner. Your actionable steps are: 1) Obtain a copy of the C&P exam if you don’t have it (via VA Regional Office or Blue Button), 2) File a Supplemental Claim formally claiming PTSD, 3) Include the C&P report as new evidence, and 4) Provide a personal statement detailing your stressor and symptoms, referencing the C&P diagnosis. This corrects the record and triggers the VA's duty to assist in developing the PTSD claim, including verifying your stressor if necessary.
