The Next Step Towards Full NPI Implementation

Effective March 1, 200. WPS is taking the next step towards full implementation of the NPI in Medicare. Medicare Part B claims must include an NPI in the primary fields on the claim (i.e., the billing, pay-to, and rendering fields). You may continue to submit NPI/legacy pairs in these fields or submit only your NPI on the claim. You may not submit claims containing only a legacy identifier in the primary fields. Failure to submit an NPI in the primary fields will result in your claim being rejected or returned as unprocessable beginning March 1, 2008. Until further notice, you may continue to include legacy identifiers only for the secondary fields.
