You Non-Profit cheats the system here!  

You claim you are a "non profit" and don't chase anyone down if they can't pay up.  Well, that's because, as a non-profit, you beg the public for "donations" and ask for grants and corporate money to cover the costs of your elaborate operations, while STILL billing the insurance companies for full reimbursements.   Your pay and salaries pockets are elaborate too, even though you boast being a "non profit"   

So, please don't attempt to disparage the legitimate HAA company here.  Personally, If you are a non-profit taking outside money, you shouldn't be allowed to bill the insurance companies, IMHO.
