Product methodology
Physician Movement Tracker
Source contract, normalization path, entity-graph join, refresh posture, and publication limits for this Branmoor product.
Status
In service. This product has a functional preview or paid engagement surface in the current site. The full licensed product may still include private exports, alerts, APIs, or buyer-specific diligence that are not exposed publicly.
Distribution Scope
Nationwide; TN clinicians; Nashville practice movement
Product Question
Tracks physician affiliation/address changes and practice movement.
Primary Sources
- NPPES NPI Registry (daily update) — Provider name, address, taxonomy, group affiliations
- CMS Medicare Provider Enrollment Public Use File — Enrollment status, reassignments, group billing relationships
- CMS Medicare Physician Compare — Practice locations and group affiliations
- Medicare attributed-beneficiary data (where available) — Patient panel shift signal
Entity-Graph Join
`npi`, organization NPI, `irs_ein`, address/geocode, parent practice entity.
Publication Rule
Branmoor does not treat raw public records as the product. A surface is publishable only when the source record is dated, normalized, source-linked, and joined to the relevant Branmoor entity identifiers with enough confidence to state the limits of the result.
Current Methodology Note
The preview register surfaces every NPPES record that changed in the most recent CMS weekly window — the canonical signal that something material moved on a provider's profile. The licensed Tracker adds the diff layer (what specifically changed), full snapshot history, daily delivery, the group-affiliation graph, and targeted alerts.
Limits
Coverage follows the underlying source. Missing state portals, gated APIs, PDF-only filings, suppressed fields, lagged agency refreshes, and entity-name ambiguity can all limit product completeness. Pending products are not marketed as live until those limits are documented on the product surface.
