Incorrect NPI Implementation Schedule Published

It has come to CMS' attention that a trade publication recently published a schedule of implementation dates, by contractor, for claim rejections based on the inability to locate an NPI/legacy identifier pair on the Medicare NPI Crosswalk. The dates listed in the publication are incorrect. Providers will be advised by their Medicare contractor as to the particular timeframe for their transition. Any other published schedules are unofficial and may have inaccurate dates. Medicare providers are urged to only rely on information from their Medicare contractors.

Providers may find a recent MLN Matters article helpful in determining how to use the NPI on Part A and Part B claims. You can view the article on the CMS Web site.

As always, more information and education on the NPI can be found through the CMS NPI page on the CMS Web site. Providers can apply for an NPI online or can call the NPI enumerator to request a paper application at 1-800-465-3203. Having trouble viewing any of the URLs in this message?

Getting an NPI is free - not having one can be costly.
