Piperd,
Sorry to hear this. Are you still in school? If you were covered under your parent's medical insurance when you turned 18 some ins companies would still cover you if you are a full time student. And some even cover a dependent until the age of 19, just depends on coverage & ins co.
If unsure, check with you parents and / or ins co to clarify coverage, etc.
In some states, where one does not have medical insurance they possibly could qualify for state aid.
I have known of some physicians and their associates who would, depending on the person and their situation, take on a case at no charge or a reduction of said charges. Let's say this was the case for you and the surgeon would do it for free, you would also need to work out arrangements with the surgery center or hospital, anest, path, etc...where I am located, if one physician on the case does it for free or a reduction then usually others will follow the same path...
Most employers offer health insurance coverage after 90 days or so of full time employment.
Where there is a will there is a way.
