The document discusses readiness for the implementation of the National Provider Identifier (NPI) among pharmacy chains and issues surrounding the transition. It notes that 92% of chain pharmacies have obtained NPIs but some smaller chains may not have. It also addresses challenges in obtaining prescriber IDs, testing of claims submission which 75% of members have done but none are currently submitting, and recommends a gradual rollout to adjudicate claims using other IDs initially and monitor data integrity before requiring the NPI. The document concludes by noting the May 23, 2007 implementation date may not be feasible and more time is needed to obtain prescriber numbers and ensure data quality.
