Many of you have noted the recent instability of NPPES and the NPI Registry. CMS has begun implementing changes that should eliminate the instability. We expect that these changes will be completed next week.
NPPES will remain in operation while these changes are being made but the NPI Registry will remain down until all changes have been implemented. We expect the NPI Registry to be back in operation sometime next week. We apologize for this inconvenience.
