Providers and suppliers will soon have to include their National Provider Identifier when submitting all claims for payment from Medicare and Medicaid or when applying for enrollment in either program, according to a final rule issued by the CMS (PDF).
The rule will become effective 60 days after its April 27 publication date in the Federal Register. It finalizes an interim final rule issued May 5, 2010.
The NPI is a 10-digit identification number—required for use in HIPAA-applicable transactions—that is used for verification and to curb Medicare and Medicaid fraud and abuse. "To maintain program integrity and ensure quality, we must make certain that only qualified providers and suppliers participate in the programs and that they bill accurately for their services," the CMS said in the rule.
