Gene,
Even if they do "maximize" your billing, they will be getting a cut of the profits, hence YOUR profits are not maximized. Become VERY familiar with proper coding and billing. I would strongly recommend
www.emuniversity.com for getting a better handle on what exactly constitutes a 99214, and how to document to that code. It's not how we learned it, but it is a necessity in today's climate.
Don't minimize the value of being your own boss and calling the shots (even though there are times...). I can't tell you how many conversations I've had with my disgruntled employed peers. There is a certain value and satisfaction to earned success. Seriously, learn to maximize your own billing and keep the change.
