Being completely objective here, but I read your original question and I think I need to explain how this works.
Doctors can refuse you for whatever reason they want, unless it is proven to be because of a negative bias that is base on race, gender or sexual orientation, etc. No doctor is obligated to take on any patient unless they are nearby and you have a condition that is considered to be an emergency.
If a doctor makes a recommendation, it is based on the parameters that you established when you made contact. For example, what they see in your photos regarding your area of loss and the total perceivable donor area. They then take into account what you’ve stated as being your ideal outcome. You may have asked for a degree of density and/or coverage that would necessitate such an assessment. Some clinics will recommend fewer grafts than others but it is all based on their own experience and skill set which may be more or less than the next clinic. Remember, you approached them based on something that made them attractive to you so you have to give a little leeway to the fact that they get the results they do because of a certain approach they take to performing surgery.
I can’t count how many times I’ve been in a consultation and the patient says that clinic “x” said 1500 grafts when the clinic I worked for said 3000 grafts and they’d challenge the assessment and even try to have it changed based on their perceptions of what they need. I get it. Most clinics will recommend lower numbers than some other clinics because they either don’t have the staff to do bigger sessions, don’t have the skillset/experience, or don’t think it is even necessary and think that having two or three sessions is normal whereas other clinics think it is fine to “knock it out” in one session.
So, was your assessment made only because of money? I have no idea but i don’t think it’s fair to make that assumption just because their assessment is larger than you wish it to be. Sometimes clinics don’t want to put their name on a final result if they know it won’t meet the patient’s expectations. Remember that there is no single clinic that is the best for everyone so consider this as a learning opportunity and move on to the next clinic that will agree with your wishes but also will explain why they do. Education about what you’re doing is of the utmost importance.
