After December 17, 2007, will Medi-Cal reject claims billed with other provider identification numbers such as a Taxpayer Identification Number (TIN)?
Yes. The TIN is a data element on the claim and not a provider identification number. Effective December 17, 2007, DHCS only accepts either an NPI or a Medi-Cal provider number until instructed otherwise. Only “atypical” providers (e.g., Blood Banks, Christian Science Practitioner, Multipurpose Senior Services Program) are exempt from submitting an NPI and will continue to use their Medi-Cal provider number.
