So far, I have worked in three different models: Government, private practice, hospital-owned/group setting.
Here is the deal. Neurologist are not paid to think, which for the most part, is what we do. Simply speaking, fitting in patients with multiple complaints and potentially complex disorders, requiring lengthy appointments means less patients per day than colleagues in other specialties. So, while you can make a valid argument that you work just as hard as say a family doctor, even though you see a third as many patients as they do per day, it does not equal more revenue.
The private practice model is dying due to ever changing rules, regulations, and laws. So, you have be very business savvy and find ways to cut your overhead while generating more revenue. It takes planning and time that does cut into your patient care and personal life. The average reimbursement for a new patient consult from a Medicaid patient is anywhere from $90 to $120. If you laugh and say "I won't see Medicaid patients in my practice" well good luck with that in Neurology. Operating costs are outrageous! In my local area, I can probably rent a 2000 square foot home for $1000/month or less but for the same amount of commercial office space, you're talking well over $4000 per month!! Consider how many patients you can see per hour, with little remibursement versus your overhead and operating costs. If you do the math, its a juggling act and some do not want the aggravation.
Now for a group model, they may not be looking at your revenue but will look at your RVUs. Hence, why seeing that extra consult for a dizzy patient that is re-admitted every three months for a "stroke" with the same exact complaints, is worth your time. It beefs up your RVUs and makes you look productive to your employer. But, at the end of the day, seeing 100+ dizzy consults per month will not earn your group big money.
