L2: Completeness and plausibility
Type 2 organizational NPIs pass checksum validation
Blocker · HPT-L2-040Every Type 2 NPI encoded in the file must be a structurally valid 10-digit National Provider Identifier (the check digit must match). A malformed NPI can't be verified against NPPES and breaks any downstream taxonomy-based lookup.
1 Type 2 NPI(s) fail checksum validation: 210018.
Citation: CY2026 OPPS final rule — Type 2 NPI requirement for taxonomy codes beginning '27'/'28'
Remediation: Correct the Type 2 NPI to the organization's real, currently-active NPI as registered with NPPES.
