The thing is, I'm not exactly sure how to charge her for this.
How do you want to charge for this? Are you a company, sub-contractor or independent contractor?
Are you in a state in which it is not illegal for a provider to enter into a fee-splitting arrangement where you can get a % of revenue
Do you want to receive a set hourly fee?
Do you want to provide full practice management, claims only, etc.. what services will you provide?
If I wanted her to pay me every two weeks, what's the best way or method to charge her for my service?
Again, are you operating as a business, sub-contractor, independent contractor? This has to be defined right off the bat
Terms on payment will be in your contract with the provider. Generally business owners and contractors receive monthly reimbursement
I'm very concerned about this because I don't want to overcharge her nor undercharge her
Anyone's help would greatly be appreciated.
