As this is a private practice, all invoices are set after the „Gebührenordnung für Ärzte“ (GOÄ).
Costs are usually almost always completely covered by
* private insurances
* the "Beihilfe"
* post officials' health insurance
* the KVB
incorporated almost always completely.
Patients insured by public/legal health insurance have to cover costs themselves, as these are set according to lower fees as outlined in the „Gebührenordnung für Ärzte“ (GOÄ, german medical fee catalogue)
