Following up on an earlier post here, CMS announced today that Phase II of Change Requests 6417 & 6421, dealing with referring physician mismatches between the NPI database and the PECOS system, has been delayed until April 5th, 2010.
Phase II of this change request orders the denial of any services referred by a physician who has a conflict between information found on the national NPI registry (NPPES) and the PECOS system. The change to the implementation schedule is being undertaken to give those physicians with conflicting information sufficient time to correct any irregularities.
For the present time, providers who bill for services referred by providers with this conflict will continue to get warning messages stating that the referring physician’s information is inaccurate. If this information has not been updated by the referring provider by April 5th, 2010, these services will be denied.


Thanks for the update, Paul. Your last post on the subject generated a lot of interest on Twitter and so I will pass this on as well.
