CMS has a few helpful tips for you to remember when applying for your NPI:

• CMS urges you to include your legacy identifiers, not only for Medicare but for all payers.
• If reporting a Medicaid number, include the associated State name. This information is critical for payers in the development of crosswalks to aid in the transition to the NPI.

CMS has also released three new educational products regarding NPI:

Suitable for All Health Care Providers

• A Subparts Fact Sheet that contains high-level information on Medicare's guidance on subpart designation. Although the guidance is geared toward Medicare organization providers, non-Medicare organization providers may find it helpful.
• An Electronic File Interchange (EFI) Fact Sheet that contains basic information and links to helpful resources that will prepare providers and their staff for the release of the EFI system. This information is essential for organizations that wish to submit electronic files for bulk enumeration, and may be of interest to any health care provider for whom an organization will be submitting NPI application data.

Suitable for Medicare Providers

• A MLN Matters Article (SE0608) that takes a detailed look at Medicare's guidance on subpart designation and the impact on Medicare providers.
