OIG LEIE, CMS NPPES, CMS CLIA POS, and CMS QCOR source references are checked against the official public pages before this source summary is updated.
NPI / NPPES
NPI records identify providers and organizations in the NPI Registry. NPI data does not validate licensure, credentialing, Medicare enrollment, or current practice authority.
HHS OIG LEIE
OIG rows are imported from the official LEIE CSV. Exact NPI matches are high confidence. Name-only matches are possible matches and require official verification.
CLIA
CLIA lab demographics are imported from the official CMS Provider of Services Clinical Laboratories CSV when available. QCOR remains linked for current official lookup and manual verification.
Source freshness check
When each official source typically refreshes
Last verified: 2026-07-27. date_retrieved: 2026-07-27. The OIG LEIE UPDATED.csv publishes monthly, the CMS NPPES Full Replacement file publishes monthly with weekly incremental update files between full replacements, and the CMS POS clinical laboratories file publishes quarterly. The source status page shows the imported timestamp, row counts, and checksum for the local copy so you can compare it against the upstream cycle before relying on a lookup.
Latest source check
Official release markers verified on 2026-07-27
These upstream markers are separate from local import timestamps. Use them to decide whether the local row count and checksum on source status are still aligned with the newest official public release.
| Source | Latest marker checked | What it means for review | Official page |
|---|---|---|---|
| HHS OIG LEIE | 06-2026 Updated LEIE Database; Last Update 2026-07-10 | The monthly replacement CSV is the current active-exclusions file; reinstated individuals and entities are removed from that file. Verify specific people or entities in the official OIG online search because SSNs are not distributed in the download. | LEIE downloads |
| CMS NPPES | July 13, 2026 Data Dissemination V.2; weekly updates through 072026_072626 | Version 2 is the current CMS bulk format. NPI issuance identifies a provider or organization for NPI purposes; it does not validate licensure, credentialing, Medicare enrollment, or current practice authority. | NPPES files |
| CMS POS clinical laboratories | Q2 2026 clinical laboratories CSV dated 2026-04-01; dataset updated 2026-07-16 (current import: Q1 2026) | The bulk file is a quarterly CLIA lab snapshot. Use it for imported demographics and certificate/status context, then use QCOR for current CLIA lookup verification. | CMS POS clinical labs |
| CMS CLIA registry / QCOR | CMS registry page last modified 2026-06-02; 2025 Laboratory Registry posted | QCOR is the current lookup path. The annual Laboratory Registry lists CLIA enforcement and sanction context for the preceding calendar year, not a real-time lab certificate feed. | CMS CLIA registry |
Screening workflow
Connect source notes to batch review
Use the batch provider exclusion screening page when a roster needs NPI identity context, OIG LEIE match labels, and CLIA lookup notes in one exportable review flow.
