Some people do not realize that future surgery will be considered to be "cosmetic" and therefore will not be covered by their own health insurance. The only way to get those costs paid is to bring a claim right now against the dog owner or other liable person. Why should you have to pay for any of these costs out of your own pocket, years from today?
An experienced attorney knows how to make an insurance company pay for future surgery. Getting the necessary legal-medical report from a credible plastic surgeon is one of the things that your lawyer will be paying for. The cost of this kind of a report can be from $250 - $750, but an insurance company will not pay for future medical treatment without this documentation.
