[The Cost of Lipoedema Treatment Exceeds the DRG Revenues - Evaluation of the Surgical Treatment Costs of Lipoedema (Stage III) at a German University Clinic].

Background: Liposuction for stage III lipoedema is a guideline-based but also time-consuming treatment, which can be carried out under specific conditions at the expense of the German statutory health insurance companies (SHI) based on a decision made by the German Federal Joint Committee ("Gemeinsamer Bundesausschuss", G-BA), the highest decision-making body in the German healthcare system, in 09/2019. We postulate that the treatment is not reflected in a cost-covering manner in the university cost system.

Methods: This monocentric, retrospective study examined the economic aspects of 92 cases in 48 lipoedema patients treated during the period from 09/2019 to 08/2023 at the expense of the SHI. These cases were filtered out using DRG coding and the Operation and Procedure Classification system ("Operationen- und Prozedurenschlüssel", OPS), and the costs and revenues per patient were calculated using the data from our internal service accounting.

Results: After an inpatient stay of 2.64±1.33 days, the total revenue was € 4,726.79±680.98. This included € 1,532.92±856.99 inpatient costs, € 2,686.02±1,174.70 in operating costs, € 940.76±189.18 in anaesthesia costs and € 63.19±125.38 in other costs that had to be paid within the clinic. On average across all treatments, this resulted in a loss of -€ 875.22 /case. In 54 cases (59%), the costs exceeded the revenue. In total, the calculation of all cases resulted in a loss of € -80,520.63. If medical personnel costs are included, this amount rises to over € 100,000.

Conclusion: The results show that the surgical treatment of lipoedema in the German DRG and university cost systems is not cost-covering. This could be relevant in the final economic assessment of the G-BA, which may result in an adjustment of the DRG revenue.
