Important NPI Dual-Use Period Changes

The Department of Health Care Services (DHCS) is extending the current dual-use period, which began on May 23, 2007, to continue beyond the NPI implementation date. Effective November 26, 2007, the NPI implementation date, a Medi-Cal provider number will continue to be required, even though the NPI is also being requested. Failure to include the Medi-Cal provider number beyond the NPI implementation date could result in delay or denial of payment.
