Get an attorney - don't go it alone!

I cannot stress enough the importance of having an attorney review all of your documents, especially your contract or agreement.
It is so important to protect yourself as the medical biller.
Also, do NOT ever change the language on your own. If a potential client requests a change in terms or in the language, take that request immediately to your attorney to discuss and review.
Many people have been hurt by "inocently" editing their contract. It ALWAYS bites you in the end. So, tread lightly.
