Healthcare investigative lead intelligence

Follow the connection.Verify the record.

SentinelGraph connects healthcare exclusion and provider records into source-linked leads for qualified human review. It helps investigators see what may deserve follow-up without turning a score or graph edge into an accusation.

Illustrative connection brief

SG-HC-MASKED-0042

Lead only

Observed record

An exclusion record and an active provider record share a normalized identity field.

Identity basis

Name-and-state candidate; exact NPI association is not established.

Relationship

One current provider address is shared across two active NPI records.

Alternative explanation

The address may be a legitimate group practice, campus, or historical record.

Next verification step: confirm identity, current enrollment, address context, and the original publisher's record before relying on the connection.

Built for qualified review teams

One evidence trail. Different investigative starting points.

Counsel

Develop and test investigative theories against a source-linked record trail.

Investigators

Move from a subject to connected providers, organizations, addresses, and source actions.

Compliance & SIU

Prioritize public-source review without turning an anomaly into an accusation.

Program integrity

See provider and network context before beginning deeper source verification.

The review path

Source

Start with a current, attributable public record.

Identity

Separate exact identifiers from name-and-state candidates.

Relationship

Show the literal source fields supporting each graph edge.

Verify

Return to the original record and document independent judgment.

Product tour

From a crowded public record to a question you can verify.

The working flow is intentionally simple: start with the strongest supported candidates, understand why a record was surfaced, then inspect the source-linked relationships behind it.

SOURCE

Select a node or relationship to see what source field supports it and what still requires independent verification.

Illustrative masked interface. Names and values are fictional; the workflow mirrors the authenticated product.

A disciplined boundary

The graph is an index into evidence—not a substitute for it.

Shared addresses, telephone numbers, officials, and professional relationships can have ordinary explanations. SentinelGraph preserves those connections as review context and shows the source basis so a qualified user can verify them.

Exact versus candidate

Exact-NPI matches and name-and-state candidates remain visibly distinct.

Source-literal edges

Every relationship carries a verification flag and can be traced to source fields.

Priority, not probability

Scores order review work; they do not estimate guilt or likelihood of wrongdoing.

Reproducible releases

Source dates, release identifiers, and provenance manifests support later review.

Controlled Early Access

90 days to test whether source-linked connections improve your review workflow.

Invitation-only healthcare access for up to five named users. The current release connects NPPES provider records with LEIE exclusion records; broader healthcare v2 coverage and effectiveness validation continue separately. Payment and written scope are required before activation, with no automatic renewal.
