[Calculating the price of a new diagnostic or therapeutic option. Example of transurethral resection of bladder tumors using photodynamic diagnostics with hexaminolevulinic acid].

New diagnostic or therapeutic options (NDTOs) are remunerated separately in the German DRG system. The Institute for Remuneration in Hospitals decides which proposed NDTOs are accepted for separate remuneration for 1 year. With this acceptance, hospitals can enter negotiations with insurance companies for an individual price of the NDTO. Because there are no general recommendations for these negotiations, we present a scheme for how to calculate an NDTO, based on the example of the NDTO for transurethral resection of bladder tumors using photodynamic diagnostic with hexaminolevulinic acid.
