All implications of possible conflict of interest between medical or psychological consultants and their medical or psychological practices will be avoided. Such consultants are not only those physicians and psychologists who work for us directly but are also those who do review and adjudication work in the State agencies. Physicians and psychologists who work for us directly as employees or under contract will not work concurrently for a State agency. Physicians and psychologists who do review work for us will not perform consultative examinations for us without our prior approval. In such situations, the physician or psychologist will disassociate himself or herself from further involvement in the case and will not participate in the evaluation, decision, or appeal actions. In addition, neither they, nor any member of their families, will acquire or maintain, either directly or indirectly, any financial interest in a medical partnership, corporation, or similar relationship in which consultative examinations are provided. Sometimes physicians and psychologists who do review work for us will have prior knowledge of a case; for example, when the claimant was a patient. Where this is so, the physician or psychologist will not participate in the review or determination of the case. This does not preclude the physician or psychologist from submitting medical evidence based on treatment or examination of the claimant.
