I wonder why you have to pay "way more"? The fees a doctor can charge vary from one speciality to another but are the same for each catégory, ie 23€ for a généraliste wherever you live in France. There is an additional charge if you call the doctor on a home call but if he considers that its justified, the SS will reimburse you. Maybe he is outside the public sector? Do you get it all back?
The 23eur fee is for contracted doctors. A non contracted doctor can charge as much as he wants. Actually there a several levels between contracted and non contracted which I understand close to nothing about

. In Paris many doctors are non contracted or contracted with free fees setting. The SS reimburses me on the 23 Eur basis then for the mutuelle, it depends on the contract subscribed.
I have the impression, homeopathic doctors are often contracted with free setting of fees. A consult may be more expensive than 23 eur even outside Paris. I once took my kid to an homeopathic pediatrician in Aix en Provence and I think the consult was EUR 60.
I cannot really compare with "classical-modern-medecine" doctors, not having much of experience with them. A consult with an homeopathic doctor is often 30 min and the first one usually lasts 1 hour. They are usually available over the phone / email when advice is needed for a quick remedie for a cold or a sore throat or a cough.
I keep hearing some friends complaining that their kids pediatrician consults barely lasts for 10 minutes.
I have some other friends who don't understand why pay more than 23 eur.
