VA can deny a claim without a C&P exam, and that is not automatically an error. VA must provide an exam or obtain a medical opinion only when the file lacks enough medical evidence to decide the claim but shows three things: a current disability or persistent symptoms, an event, injury or disease in service, and an indication that the two may be associated. That third element is a "low threshold," but a bare statement that a condition is related to service does not always meet it. Check what was in your file before the decision, not what you sent afterward.

The rule VA has to follow

The duty comes from 38 C.F.R. § 3.159(c)(4). An exam or opinion is necessary when the record "does not contain sufficient competent medical evidence to decide the claim," but contains competent lay or medical evidence of a current disability or persistent or recurrent symptoms, establishes an in-service event, injury or disease (or a qualifying presumptive condition), and "indicates that the claimed disability or symptoms may be associated with" service or another service-connected disability. The regulation adds that the third element "could be satisfied by competent evidence showing post-service treatment for a condition, or other possible association with military service." For a Supplemental Claim, the duty applies only if new and relevant evidence is presented or secured.

The Court of Appeals for Veterans Claims set out the same four elements in McLendon v. Nicholson (2006). On the third, it said the evidence need only indicate that there "may" be a link: "This is a low threshold." For toxic exposure claims, the PACT Act added a separate duty in 38 U.S.C. § 1168: when you show a disability and a toxic exposure risk activity in service, and that is not enough to grant the claim, VA must provide an exam and opinion unless it finds "no indication of an association."

First, confirm what did and did not happen

"No appointment" can mean several different things. VA's claim exam page says that when your file already has enough medical evidence, VA follows the Acceptable Clinical Evidence (ACE) process and reviews your medical records instead of scheduling an exam. So check the decision's evidence list for a records-only opinion or DBQ. Also check whether VA used an exam from another claim, found your private evidence adequate, decided there was no in-service event, denied the claim on a legal ground, or scheduled an appointment that was missed or rescheduled. Each of these leads to a different argument, or to none.

If your denial says "no nexus" and no exam happened, do not jump straight to "VA had to order one." Find the current-disability evidence, the specific service event or qualifying presumption, and whatever in the pre-decision record suggested a link.

Two Board decisions, two different answers

Exam not required. In Board decision A25004268, January 16, 2025, a veteran claimed a mental health condition caused by pain from his service-connected disabilities, and his representative argued he was owed an exam. His service and VA medical records contained no mental health complaints, diagnosis or treatment. The Board of Veterans' Appeals (the Board) found no competent evidence of a current disability and held that his "mere conclusory generalized lay statement that his service-connected disabilities caused a mental health condition is insufficient to require the Secretary to provide an examination." It found the McLendon elements unmet and denied the claim. It also noted that a mental health condition requires a formal diagnosis before it can be service connected.

Exam required. In Board decision A25036059, April 18, 2025, a veteran's private rheumatologist had diagnosed psoriatic arthritis. VA had conceded a toxic exposure risk activity from his job repairing light wheeled vehicles, and his claim form described carrying a rucksack and a machine gun on road marches and lifting heavy tires and parts. VA examined him only on the toxic exposure theory. The Board found that VA should also have provided an exam on the direct theory, because "the available evidence meets the low threshold for an examination," and that the toxic exposure opinions were inadequate. It remanded for a new exam covering both. It did not grant service connection.

The difference was the file. In the first case there was no evidence of a current condition and only a general assertion of cause. In the second there was a diagnosis, a specific account of what happened in service, and a theory VA never examined. An exam on one theory does not cover another.

Use only evidence VA had before the decision for an argument that VA made an error. Keep anything newer separately labeled, because it belongs to a different review route. VA's duty-to-assist page and the full regulation are more reliable than a rule of thumb that every claim gets an appointment.

A missing exam is not the same as a bad exam

A missing exam and an inadequate exam are different errors. If you did have an exam and the report gets facts wrong, C&P exam report errors shows how to document the disagreement. When VA gives an exam, it must be adequate; this Board case breakdown shows how the Board handles an exam that missed required findings. In Claim Raven's analysis of 2024 to 2025 Board decisions, the Board found a VA exam inadequate in 38,115 condition records, and where that finding was tied to the outcome, 78.0% of 27,680 records were remanded. These are appeals of already-disputed claims, so the figures describe a pattern, not your odds. The data does not measure missing exams separately, but the second case above ended the same way: a remand for development, not a grant. This guide explains what happens after a Board remand. For one skin claim the Board sent back because VA never ordered an exam, see this case breakdown.

Respond through the right review lane

If VA overlooked a record it already had, or skipped an exam the rule required, a Higher-Level Review looks at the same record, and the reviewer can identify a duty-to-assist error made before the decision and send the claim back for development. It does not accept new evidence. If you now have new and relevant evidence, such as a diagnosis or a treating clinician's note linking the condition to service, see Supplemental Claims. A Board appeal is also available. Check your letter and VA's decision review FAQ for deadlines and effective-date effects.

If you cannot tell whether VA used a records-only opinion, Claim Raven's Raven Eye tool, offered on this page, can explain the evidence passage beside the original text. Claim Raven sells the tool; it does not decide whether VA breached a legal duty or order an exam.
