thank you for your question. I will answer only on the basis of that you told, and that answer because of the complexity of the facts on the one hand and me under the contract available to only two-hour processing time on the other hand can only be approximate.
After your account you have with the dentist a treatment contract concluded for the treatment and agreed a fee of € 380,00. Then the dentist may not exceed this amount significantly. The agreement on the fee has to be concluded before treatment and in writing.
It is later that the treatment would be more complicated than the next-sight was and the fee of 380 € would not be covered, the dentist will inform you. If he fails, he is not entitled to an additional fee. But the only transmission of the HKP creates not a higher fee. However, should the dentist for the preparation of the HKP may ask a separate fee.
You should still tell me whether your health insurance has submitted a permit of the HKP. Moreover, I would have to know if you have your consent to the HKP declared understanding to a higher fee. If this is not the case, the dentist has no further fee shall.
Ask for the dentist to answer your health insurance.
The second invoice, you do not pay.
