PREFERRED CARE AT MERCER LLC

Cross-source identifiers

Every current identifier attachment, with the link method and confidence carried verbatim — deterministic links are 1.000; probabilistic links surface their real matcher confidence, never rounded up.

Graph edges

One-hop relationships — ownership, chain membership, operation — each backed by a federal source row.

Current record

Every current claim asserted about this entity, grouped by provenance subject. Each cell carries its upstream federal source.

Provider screening signals

NPI-keyed source families read directly for 1528440013: federal and state integrity lists, CMS Open Payments, Order and Referring eligibility, Medicare opt-out, and enrollment revalidation. Each cell carries its own source and 14-tuple provenance. A screening aid — re-confirm any match against the primary source before acting; absence means nothing on file in the data Fonteum currently holds, never a guarantee none exists.

Point-in-time

Reconstruct this record as of any date, or diff it between two dates — both axes of the bitemporal store (bitemporal-read/v1): valid time (when a fact was true per the source) and recorded time (what the store knew when).

Pick a date to reconstruct, or two dates to diff. Equivalent JSON: /api/v1/history/{subject_type}/{subject_id}?at=… and …/diff?from=…&to=…
