The objective of this study is to compare different payment systems in high frequency procedures performed in ambulatory and hospital services of complexity 2 and 3, these complexities being the most expensive within an insurer and because in Colombia it was restricted the contracting under capita for this level of complexity, with the introduction of the law 1438 of 2011, to evaluate the differences of the costs. The study was descriptive with an analytical component. In this work the costs in a health insurer, for 1298 technologies in a period of one year, were calculated by the following contract modalities: Capita, Global Prospective Payment (PGP) and Event. After the study, it is evident that the prospective modalities are less expensive than the retrospective ones, however, the frequency of use and the average cost of the individual technology must be taken into account, in order to evaluate which set of payment systems the cost.
