See every physician entering your catchment — first

Referral development is a timing problem

A physician liaison's whole job is being the first familiar face when a referral relationship is forming. The catch is that the moment a relationship is most movable — when a physician opens a new office, joins a group in your market, or relocates across town — is precisely the moment you can't see on a list you bought last year. By the time a static database catches up a quarter or two later, the new cardiologist has already picked an imaging center, the relocating orthopedist has already settled a hospital preference, and the brand-new urgent-care group has already wired its referral pad to a competitor.

The market churns more than most liaison teams budget for. Roughly 40,000 physicians relocate or change practice every year, a 7.6% annual turnover rate, and about 8,800 medical practices change ownership or affiliation annually as consolidation continues. On top of that, the country mints roughly 78,000 new clinicians a year entering practice. Every one of those events resets a referral pattern somewhere — and in aggregate they mean the physician map of your catchment is materially different than it was twelve months ago. Provider Signals turns that churn into a weekly worklist instead of an annual surprise.

What a physician-liaison team can actually do with it

Provider Signals watches CMS NPPES — the national NPI registry that every U.S. clinician and organization must keep current — and surfaces the movement signals that matter to referral growth, filtered to your exact territory:

• Newly enumerated physicians, NPs & PAs entering your catchment — the providers building a referral pad from scratch, where being first is worth the most.
• Relocations into and out of your market — a practice address change is your earliest signal that a referrer's loyalties are up for grabs, or that an established referrer just left and needs to be replaced.
• Brand-new organizations — newly enumerated groups, clinics, and ambulatory sites in your service area, before they appear in any directory.
• Reactivations — providers returning to active status, often re-establishing where they admit and refer.

Filter all of it by NUCC taxonomy (target the specialties that feed your service lines — cardiology, orthopedics, oncology, primary care), by state, county, and ZIP radius around each campus, and by individual vs. organization. Save a territory, and new matches arrive as real-time, daily, or weekly alerts — so a liaison covering three counties gets a routed call list instead of a research project. Export to CSV for your CRM, or pull it through the API into the system of record your physician-relations team already runs.

For recruiting and network growth, not just outreach

The same signal feed serves the in-house recruiting and network-development side of the house. With nearly 395,000 physician group practices in the country and consolidation steadily moving physicians between independent practice and system employment, the providers worth recruiting into your medical group — or aligning into your clinically integrated network — are constantly in motion. A physician who just relocated into your market, or whose practice just changed ownership, is far more reachable than one who has been settled for a decade.

Pair the relocation and new-enumeration feeds with your growth targets and you can spot alignment candidates the week they become catchable: the independent specialist who moved into a ZIP near your campus, the new NP cohort entering primary care in an underserved county, the small group whose ownership change signals it may be open to affiliation. It is the same intelligence physician liaisons use for referral capture, pointed at network growth instead — a single source for outreach, recruiting, and referral-leakage defense.

Why teams switch from a static database

The legacy provider-intelligence platforms were built for static reference, not movement, and priced for procurement committees — incumbents like Definitive Healthcare run roughly $50,000 a year, and enterprise sales-intelligence suites land in the same range. You sit through a sales cycle, sign an annual contract, and still get a database that tells you who practices where, not who just moved. Provider Signals is built the opposite way: movement-first, self-serve, and priced so a single liaison can start today.

Start free, map your catchment, and let the weekly feed do the prospecting. See how the signals work on the Provider Signals overview, line it up against recruiting on the physician recruiting page, or size a plan on the pricing page.
