Understanding National Provider Identifier (NPI)
Explanation:
The National Provider Identifier (NPI) is a unique identification number for covered health care providers. Regarding the true statement about NPIs, Option D is accurate: The Academy of Nutrition and Dietetics encourages all Registered Dietitian Nutritionists (RDNs) to obtain an NPI even if they don't believe they will use it. This recommendation supports the professional growth and practice of RDNs, ensuring that they are prepared and registered to participate in various healthcare settings and billing processes. In contrast, Option A is incorrect because an Employer Identification Number (EIN) is not necessarily tied to obtaining an NPI. Option B is also incorrect as the NPI remains the same regardless of state relocation, and Option C is inaccurate since NPIs are not automatically deactivated after 12 months of non-use.
