on March 17 I would have an appointment with the dermatologist. Due to corona, I was called by the hospital to cancel the appointment. then the doctor contacted me and prescribed an ointment (this conversation took less than 5 minutes). I have never made an appointment for a telephone consultation myself and my appointment was canceled. now i did receive a letter from my health insurance this morning that i have to pay 200 euro for this phone call (which i did not ask for and did not make an appointment for) for this "consultation". I absolutely disagree with this!
