Have done this for a part of my practice in the past. Keep in mind the fee schedule for the procedures and visits you do and what you will be paid.
There will also be pressures to agree with the plaintiffs attorney and when you don’t you may not work there anymore. Very slimy business. An RFA could pay 5-10k easily. They’ll be giving you a few hundred. If you are ok making others rich while you take all the risk and selling your soul jump right in.
