IVUS may be separately reported when done with dialysis access codes 36901-8. However, there is little literature to guide or support its use in dialysis access procedures at this time so it is not clear that carriers will pay for the service. IVUS does have literature supported application in central venous disease (not associated with dialysis access) and peripheral arterial disease. It is not included in the coding manual at this point because of the lack of scientific evidence to guide its use. Tim
