I treated a patient after an auto accident and got a lien signed by both her and her attorney. She was not at fault and the other party's insurance is responsible. My total medical bill is $4175.00 and I discharged her as condition resolved without complication. I am a solo practitioner, that is, I am not with a medical / chiropractic group. Her attorney received a settlement offer of $7500.00 and stated that I was legally responsible to reduce my fees due to the Made Whole and Common Fund Doctrines and cited CA Civil code 3040(f). I disagreed and stated I had a lien and that I am not required to reduce my fees. He is suggesting he will file an interpleader if I don't reduce. Can he do this? I might add that my fees are lower than the Medicare fee schedule, which I can prove.
