Indicator Dilution Studies (Winter 1991)
Winter 1991 page 25 Coding Clarification Indicator Dilution Studies We have been asked to clarify the intended use of the codes related to indicator dilution studies. Indicator dilution studies are used to measure cardiac output in cardiac catheterization laboratories. The indicator dilution technique is based on the principle that the volume of blood flow is related to the average dye concentration and the time taken for passage of the dye. 93561 Indicator dilution studies such as dye or thermal dilution, including arterial and/or venous catheterization; with cardiac output measurement (separate procedure) 93562 subsequent measurement of cardiac output The note...
