A Compensation and Pension exam is scheduled by the VA and conducted by a VA-contracted examiner. The examiner's report becomes part of the veteran's claims file and carries weight in the VA's adjudication of the claim. When the examiner's opinion is unfavorable (concluding that a condition is not connected to military service, or that a nexus cannot be established), that opinion can significantly affect the outcome of a claim or appeal.
A rebuttal medical opinion is an independent MD-authored opinion that responds to the unfavorable C&P exam finding by providing a competing medical conclusion. It does not ask the VA to disregard the C&P exam. Instead, it places a different clinical perspective in the evidentiary record, supported by a thorough review of the veteran's records and sound medical reasoning. The VA must then evaluate both opinions and, if it chooses to favor one over the other, explain its reasoning in writing.
This process is grounded in the VA's own regulations. Under the duty to assist and the rules governing the weighing of medical evidence, the VA is required to consider all competent medical opinions in the file. A well-constructed rebuttal opinion directly addresses the evidentiary weight of the C&P report and gives the adjudicator a complete medical picture on which to base the decision.
