This is from a previous post by Linda:
"There have recently been a few threads on this. How I do it is based on hourly rate, what I want to make per hour. My formula goes like this:
For this example I will use an hourly rate of $25 p/hour.
I determine the amount of time I will need per week per client (estimated). This is easy if you have been billing for the provider and it's always a good idea to calculate how much time you spend on each client no matter how you are charging. For this example we will say this provider will take or takes 12 hours per week.
I then add up my expenses PER client (this should NOT include any fees for the cost of doing business such as computer, attorney, books, education, etc) only costs such as clearinghouse, postage, phone, claim forms, software per client fees, envelopes, ink, paper, etc.. should be included in these costs. For the sake of this example we will use an estimated cost of $500
I then take my hourly rate of $25 and multiply it by 12 hours per week=$300 per week X 4 weeks= $1200 per month
I then add my estimated costs for each month $1200 + $500 = $1700 monthly flat fee total.
To create the sliding scale I then break down (again estimating) how many patients/claims I can comfortably do per hour. For this example I will use 8 patients. That will equal $25 (hourly) per every 9 patients added. That will allow you to continually get paid for your time and allow for growth of the practice. Remember to increase you "costs" and I do this once every 6 months as per my contract.
Nice and simple, and biggest factor is I get paid for all my work.
