Freshness verification
How to read source status before screening
Last verified: 2026-07-27. date_retrieved: 2026-07-27. Use the row count, imported timestamp, checksum, and official source link together before relying on a lookup result. A current status page helps identify which public file was screened; it does not provide legal clearance, licensure verification, or a final credentialing decision.

Upstream publication cadence
How often the official sources publish
Last verified: 2026-07-27. date_retrieved: 2026-07-27. Compare the imported timestamp above with each upstream cadence to judge whether a local row is current relative to the official cycle. The “Latest confirmed” note in each row records the most recent official release we checked directly on the source on 2026-07-27, so you can gauge upstream currency even when our import timestamp is unavailable. If our import lags the upstream cycle, treat possible matches as preliminary and verify on the official source.

FAQ
Practical notes
Why check source status before an OIG exclusion lookup?
The source status page shows which OIG LEIE file was imported, when it was imported, and which official OIG link should be used for manual verification before acting on a match.
How does source freshness affect a CLIA lookup?
CLIA pages use imported CMS clinical laboratory rows when available and link back to CMS resources. Check the source status page for the import timestamp, then verify current certificate context in official CMS systems.
