Entity resolution

Entity resolution for healthcare provider data.

Entity resolution decides whether records that look different actually describe the same real-world entity. In healthcare provider data, that entity may be a clinician, practice, clinic, hospital department, or organization with one or more NPIs.

Quick answer

Entity resolution combines matching, verification, and evidence review. For provider data, a useful entity resolution process must account for names, locations, phone numbers, organization names, NPI type, and registry facts rather than relying on one fuzzy score.

Teams replacing manual NPPES searches

Beyond fuzzy matching

A high string score is not the same as identity.

Fuzzy matching is useful for candidate discovery, but a provider data workflow needs a stronger final decision. The registered name must plausibly identify the input entity, and supporting signals should explain why that record was chosen.

  • Nicknames and name order swaps can hide obvious individuals.
  • DBAs and former names can hide organizations.
  • Medical office buildings can create dangerous same-address collisions.

Healthcare constraints

The downstream cost of a wrong entity is high.

Wrong provider identities can affect claims cleanup, referral routing, directory hygiene, CRM enrichment, and credentialing prep. Entity resolution should be conservative enough to return no-match when evidence is not good enough.

  • No-match is a valid outcome when evidence fails.
  • Confidence should reflect corroboration, not optimism.
  • Exports should preserve the reasoning needed for review.

Workflow

A defensible match has a trail.

01

Generate candidates

Use registry search, names, state, organization names, and known NPI hints to find plausible records.

02

Filter by entity type

Respect whether the row should resolve to an individual, an organization, or either type.

03

Score corroboration

Use street, ZIP, city, state, phone, and specialty as supporting signals after name identity is plausible.

04

Expose the decision

Return enough reasoning and source evidence for a reviewer to accept, reject, or rerun the row.

Better decision criteria

What separates lookup from resolution.

Signal
Weak approach
NPI Finder approach
Fuzzy match
Optimizes for similar strings.
Uses similarity to find candidates, then verifies identity with evidence.
Deduplication
Merges records that look close.
Keeps records separate when the evidence points to different entities.
Automation
Hides the decision in a score.
Shows the facts, confidence grade, and source URLs behind the result.

Common questions

Entity resolution is the process of deciding whether records from one or more datasets refer to the same real-world person, organization, or object.
Healthcare provider data includes individual and organization NPIs, practice locations, DBAs, former names, credentials, and public registry records. Those constraints make a bare fuzzy score insufficient.
Yes. In provider data, a no-match is often safer than choosing a nearby entity when the evidence does not plausibly identify the input row.
