I've had several people over the years ask about billing insurance companies for the massages I do for them. I've tried, unsuccessfully to bill insurance companies. They simply don't think I'm necessary it appears. I have come up with a few "work arounds" for those that want to try and be reimbursed. In most cases the insurance company will apply my fees to your deductible.
I do and can bill for auto accidents and injuries at work (workman's comp claims).
