What does the process of credentialing typically verify in CPT coding?

The correct answer is B because the process of credentialing primarily involves verifying the qualifications of healthcare providers. This includes checking their licenses, education, training, and other relevant credentials to ensure they are legally and professionally qualified to provide care in their specific fields of expertise. Credentialing is a critical step to maintaining the standards of medical care in facilities and insurance networks, as it assures that providers are not only licensed but also adequately trained to deliver services safely and effectively.

While the other choices touch on aspects of a provider's practice or business, they do not accurately encompass the primary focus of credentialing. For instance, the number of patients seen pertains more to productivity rather than qualifications, and the specialties or insurance affiliations do not directly reflect the verification of a provider's formal credentials and training. Thus, option B is the most accurate representation of what credentialing verifies in the context of CPT coding.
