LPN interested in Private Duty Work. Can I bill private insurances

Hi,
I live in florida and have been an LPN for many years.
I recently ran into a fellow LPN and she started telling me how she works directly with private insurance companies and bills them.
She basically is bypassing the agency which is a win-win for the insurance company and me.

Have any of you heard this???
If so how do i become a provider of theirs?

On a side note, how hard is it to become an LPN medicaid provider in florida?

Thanks ahead of time.
