Certification in Medical Billing

Confused by the different certification in medical billing credentials? Here’s the top ones to help you sort it out and determine which is best for you. Also includes the cost and the professional organizations that offer them.

When the topic of medical billing certification comes up, it can be a topic of spirited discussion. Being credentialed in medical billing has not traditionally been very prevalent.

And that has probably hurt the perception of the profession. As compared to medical coding which has always encouraged certification and recognized it benefits. It also enhanced the perception of the individual and the profession as a whole. Certification for medical billing is also an advantage whether seeking a job or consultant opportunity as it conveys professionalism and evidence you meet high standards.

So here’s the organizations offering certifications in medical billing and their requirements.
