history: Medical bills can really destory a family financially. I know that Medical billings is a payment practice in the USA. It is, and sometimes there is no help available to people who struggle the most. Medical bills are not required by law to take any exams or anything like that. What exams do you mean? There are a few exams they are encouraged to take, like CMRS and RHIA, but they are not required. Oh, well I'm sure there are some sorts of laws that medical billers need to follow.
knowledge: Certification schools are intended to provide a theoretical grounding for students entering the medical billing field.
