Consultation fees vary from doctor to doctor. More and more cosmetic surgeons will offer free consultations or charge a nominal fee which can sometimes be applied to the purchase of a procedure. I know of one office that takes your credit cards and charges you $75 ONLY if you don't show up! Call and find out the fee schedule ahead of time. Most plastic surgeons do not charge too much, if anything, to consult with prospective cosmetic surgery patients.
COnsultation fees will vary around the country and from doctor to doctor. I believe in consultation fees, because I think that it eliminates wasted time for both the doctor and the patient. A serious patient will pay the consultation fee expecially to a doctor that they are interested in.
