L2: Completeness and plausibility

Type 2 organizational NPIs pass checksum validation

Blocker · HPT-L2-040

Every 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: 210028.

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.
