[Economic aspects of interdisciplinary plastic surgery: change in Diagnosis-Related Groups (DRG) due to procedures of reconstructive microsurgery].

 Reconstructive microsurgical procedures lead to a significant increase in revenue in interdisciplinary surgical cases. However, a significant increase in resource consumption is observed as well. Moreover, these additional costs are not always adequately reflected in the revenue of the DRG. This especially applies to DRGs with a high initial cost weight. To ensure modern, individual, patient-oriented and guideline-compliant patient care, there is, therefore, an urgent need to adapt the (G-)DRG system to the additional resource consumption. In addition, in the case of interdisciplinary surgical cases, a clear internal cost allocation must be carried out in accordance with the surgical resource expenditure.
