Breast cancer surgery and financial reimbursement in Germany.

The reimbursement for breast cancer-specific operative interventions in Germany is regulated by the diagnosis-related group (DRG) system. The essential elements of the German DRG system, which was developed as a per-case lump-sum payment system, are presented, including the participating institutions. The actual treatment situation in breast cancer surgery is now aptly reflected in the introduction of the OPS (operation and treatment procedure classification) 2012. This is oriented on the classification model of Hoffmann and Wallwiener, with its complexity-based differentiation that reflects the basic idea of different resource usage. Despite the actual potential of the appropriately differentiated encryption of surgical procedures, which illustrates their differences in resource costs and consumption, appropriate reimbursement has still not been achieved. Hopefully, in the future the calculation of the DRGs in the field of breast cancer surgery will be based on data feedback from the hospitals and treatment institutions, and will be more suited to the main purpose of the DRG system, i.e. that reimbursement reflects resource expenditure. A necessary basic tool for differentiated, complexity-oriented encryption has been achieved with the OPS 2012, which mirrors our classification model for oncological, oncoplastic and reconstructive breast surgery.
