Payment

(a) Psychologists who are fully or partially salaried by a general hospital, public or private institution, group practice, or clinic shall not receive payment from the department unless the psychologist maintains an office for private practice at a separate location from the hospital, institution, or clinic in which the psychologist is employed and bills for a service provided to the psychologist's private practice client at the psychologist's private practice location only. (b) Payment for services directly performed by a psychologist in private practice shall be made at the lowest of: (1) the provider's usual and customary charge to the general public; (2) the lowest Medicare rate; (3) the amount in the applicable fee schedule as published by the department; (4) the amount billed by the provider; or (5) the lowest price charged or accepted for the same or substantially similar goods or services by the provider from any person or entity.
