Currently Health insurance billing is really messed up and in a number of cases health insurance companies reject bills from health care providers for a number of silly reasons like punctuation, etc... We need to standardize the medical billing industry and bills that pass the standard, will be required to be payed. The web has complex validation software for things like CSS, XHTML, HTML 4.01 transitional, argh, well its complicated. There is no reason that a validation engine for medical bills could not be built and maintained by the government.
