TKay - you haven't told us how you have been doing your billing. So how can we know what you need to do differently?
1. What documents did you use to bill as an employee? What documents will you need, and how will you get them, to bill as an independent biller?
2. What equipment did you use to bill as an employee? What equipment will you need to bill as an independent biller?
3. What software did you use to bill as an employee? What software will you need to bill as an independent biller?
4. What paper products did you use / will you use?
5. What educational material did you use / will you use?
6. How did you get paid as an employee? How will you get paid as an indendent biller?
7. Who was legally responsible, under HIPPA, for any mistakes you made as an employee? Who will be responsible, under HIPPA, for any mistakes you make as an independent biller? That is, will you become a business associate as an independent biller? If yes, how will you handle that, and the contracts involved?
8. At a minimum, you could simply be moving from employee to independent contractor. You could go the the offices of your clients and use all of their resources to do their billing, just as you do as an employee. It's just that you would get paid differently as a contractor, and would be responsible for your own taxes and liability insurance and business associate contracts, etc. But, since the client would be paying for all of the business expenses involved in the billing, you would not get paid for those expenses. Or:
9. At a maximum, you could move all the work to your own office, using your own equipment, supplies, and other resources to conduct their billing. Since you have assumed these expenses necessary to do your client's billing, you should charge them for that - in addition to charging for your labor. As in Point #8, you would be responsible for your own taxes and liability insurance and business associate contracts, etc.
Now - what was your question?
P.S. - have you read through this thread?
