I only spoke to the doctor’s assistant but I still received an invoice. Why is that?

Any time you contact the GP Emergency Post and are given medical advice over the telephone, you or your health insurance provider will receive an invoice. You will still receive an invoice even if your only contact was with the doctor’s assistant and he/she provided you with medical advice. The doctor’s assistant has been trained for this and does this under the responsibility of the GP on duty. The medical advice given by the doctor’s assistant is always assessed afterwards by a GP.
