Are health plans permitted to require a National Provider Identifier (NPI) for transactions with Medicaid programs?
No. States typically do not meet the definition of a covered health care provider under 45 CFR 160.103, and therefore, are not eligible to receive an NPI. If states encounter situations where plans are requiring them to submit an NPI, they can submit a formal complaint to the Office of E-Health Standards and Services (OESS) in CMS by using the online Administrative Simplification Enforcement Tool (ASET).
