Physician-practice intelligence is not created by stacking more rows into a spreadsheet. Each source was built for a different administrative, regulatory, business, or disclosure purpose. Those purposes shape the fields, update cycles, omissions, and errors a growth team will encounter.
PracticeMap uses source-specific signals to answer bounded questions. An NPI can help resolve provider identity. A Florida filing can identify a legal entity. An official site can show how a practice presents its current roster. A federal or payer file can add enrollment, billing, network, or program context. None of those signals should silently become proof of ownership when the source did not establish ownership.
The product therefore keeps provenance, dates, snippets or relevant fields, confidence, and review status attached to the decision. The LLM or analyst summary is a navigation aid; the underlying evidence remains the part a human should inspect.
