Are there any recent changes to requirements for the usage of the National Provider Identifier for Medicare Part B claims?

Effective March 1, 2008, all Medicare Part B claims must include an NPI in the primary provider fields on the claim. The primary provider fields refer to the billing provider, pay-to provider, and rendering provider fields. You may continue to submit NPI/legacy pairs in these fields or submit only your NPI. Failure to submit an NPI in the primary provider fields will result in your claim being rejected, beginning March 1, 2008. Note: If you already bill using the NPI/legacy pair in the primary provider fields and your claims are processing correctly, you should begin submitting a small number of claims containing only the NPI in the primary provider fields. This test will serve to assure your claims will successfully process when only the NPI is mandated on all claims.
