i've done medical billing systems too and it is, indeed, crazy but what's make you think the gov. would be any better?

I wrote a specialized service dealing with Medicaid in a handful of states and it was even worse than normal. The incompetence at Medicaid is dangerous. Formularies, eligibility, reimbursements changed randomly with reimbursement changes retroactive to some random date. I have zero faith in any part of gov to get it close to right.
