What You Need To Know About Medical Credentialing

As a medical professional, medical credentialing is most likely a topic you hear of often. Medical Credentialing is a method used to assess the qualifications and practice history of a doctor. This systematic, in-depth, and time-consuming process also includes the process of becoming associated with insurance companies (also known as provider enrollment) so that you can accept third party reimbursement. Becoming associated with an insurance company allows you to become an in-network provider. With the cost of healthcare today, medical credentialing has become more important and more necessary than ever.

Medical Credentialing has become more important as the scope of services covered by insurance plans has become broader. With the introduction of The Affordable Care Act, there are now less restrictions regarding pre-existing conditions. In fact, no insurance company is allowed to deny you coverage, charge you more, or refuse payment on essential health benefits surrounding pre-existing conditions. For this reason, patients are no longer seeking out specialists that are out of network.


As you begin the medical credentialing process, you may notice that insurance companies preferred provider networks, or insurance panels, are very full. This is making the process of becoming an in network provider more challenging with barriers to entry becoming more difficult to meet. Additionally, you may run across an insurance company saying their insurance panels are closed. However, this usually means that the insurance company is being highly selective on which providers they are allowing on their list, which results in more work on your end.
