Do I Need Another Nexus Letter?
Read which element was denied
has three elements: a current disability, an in-service event, injury, or disease, and a between them. Caluza v. Brown, 7 Vet. App. 498 (1995); Shedden v. Principi, 381 F.3d 1163 (Fed. Cir. 2004). A names the one VA found missing, usually in a sentence such as 'the evidence does not show' followed by the element.
- 'Not incurred in or caused by service' — a finding. An adequate opinion is relevant here.
- 'No current diagnosis' — an opinion about causation cannot supply a diagnosis that is not in the record.
- 'No evidence of an in-service event' — this is a records problem: personnel files, unit records, deck logs, or under 38 U.S.C. § 1154(b).
- 'Evaluation criteria for a higher rating are not met' — was granted. The dispute is measurements against the rating schedule, not causation.
- A deferred or remanded issue — nothing has been decided yet.
When a second opinion actually adds something
The probative weight of a medical opinion comes from its reasoning, not from the number of opinions in the file. Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008). A second opinion adds value when the first one lacked a , relied on an inaccurate history, or did not address the specific theory in the case — rather than causation, for example. Two opinions that say the same thing with the same reasoning do not weigh more than one.
- The existing opinion states a conclusion without medical reasoning.
- The opinion relies on a history that the records contradict.
- The was actually about of a pre-existing or non-service-connected condition and the opinion only addressed direct causation.
- A VA examiner's negative opinion is unrebutted and the file contains no competing opinion at all.
What to do before paying for another one
- Obtain and read the claims file, including the examination report the denial relied on. The reasoning in that report is what any new opinion has to engage with.
- Identify the review lane the situation calls for: new evidence points to a , an error on the existing record points to a , and a legal disagreement points to the Board. 38 CFR §§ 3.2500, 3.2601, 20.202.
- Check whether the gap is evidentiary at all. A duty-to-assist failure under 38 CFR § 3.159 is corrected by VA, not by the 's wallet.
- Confirm the provider writing any opinion is qualified to address the specific condition and has the records in front of them.
A note on cost and accreditation
Medical opinions are a medical service and are priced by the provider. VA accreditation is separate: only an accredited agent, attorney, or recognized representative may assist in the preparation, presentation, and prosecution of a , and fees for representation may be charged only after a decision has been issued. 38 U.S.C. §§ 5901, 5904(c)(1); 38 CFR §§ 14.629, 14.636(c). Verify anyone before you sign using VA's Office of General Counsel accreditation search.
An accredited agent or attorney may charge a fee only for work performed after VA issues a decision on the (38 U.S.C. § 5904(c)(1); 38 CFR § 14.636(c)). Fees must be reasonable, disclosed in writing, and filed with VA. Nothing here predicts an outcome in any individual case.
Find the sentence in your decision that names the missing element
A medical opinion only helps if nexus is what VA found missing. The reasons-and-bases section names the element in one line.
| If your record shows this | What it means |
|---|---|
| 'Not incurred in or caused by service' | A nexus finding. An opinion with real rationale that engages the negative examiner is relevant here. |
| 'No current diagnosis' / 'no diagnosed disability' | A diagnosis problem. A causation opinion cannot supply a diagnosis that is not in the record. |
| 'No evidence of an event, injury, or disease in service' | A records problem — personnel records, unit records, deck logs, buddy statements, or 38 U.S.C. § 1154(b). |
| 'Criteria for a higher evaluation are not met' | Service connection was granted. The dispute is measurements against 38 CFR Part 4, not causation. |
| 'The examiner did not provide a rationale' | Adequacy issue under Nieves-Rodriguez and Barr — the existing exam is the target, not a new purchase. |
| The issue is listed as deferred or remanded | Nothing has been decided; buying evidence now may be premature. |
This is educational. Which element a specific decision turned on can only be confirmed by reading that decision and the examination report behind it.
