A. Diagnostic services of psychologists and physical therapists

When a psychologist or physical therapist is a salaried member of the staff of a hospital, their diagnostic or therapeutic services to inpatients of that hospital are covered on a reasonable cost basis in the same manner as the services of other nonphysician hospital employees. The services of a psychologist or physical therapist who is not a salaried staff member are covered if furnished by the hospital as part of the services it ordinarily furnishes under arrangements which provide for billing to be handled by the hospital.
