Provider Signals™Know when a provider moves — the week they change practice.
When a provider changes their practice address in CMS NPPES, it's the strongest early signal of a real relocation — a new employer, a new territory, and a fresh set of buying decisions. Provider Signals Growth diffs the weekly NPPES release to surface provider relocations in the markets you watch, so you reach them while the move is still new.
Why a provider relocation is a buying signal
A provider who has practiced in the same place for years is a cold prospect — every vendor in their market has already called. A provider who just moved is the opposite. A relocation means the provider has a new employer or has opened a new location, and with it a wave of decisions that are briefly open again: new equipment and supplies, a new EHR or billing setup, new malpractice and credentialing, new referral relationships, and new payer contracts. Reach them in that window and you're competing on merit, not incumbency.
Relocations are also the change most likely to break your existing data. The address on your CRM, your mailing list, and your claims records all go stale the day a provider moves. Tracking relocations keeps your outreach deliverable and your records current — the same signal serves growth and hygiene at once.
What counts as a relocation — major vs. minor
Not every address edit is a real move. Provider Signals classifies each practice-address change so you act on the ones that matter and aren't buried in noise. Move signals are keyed on the NPPES practice location fields — address line 1/2, city, state, ZIP, CBSA, and county — compared release over release.
| Change | Classified as | Why |
|---|---|---|
| City / metro / state changed | Major — real relocation | New employer or new territory. The highest-intent move signal. |
| License-state change alongside the move | Major — corroborated | A new state license reinforces a genuine cross-market relocation. |
| Same city + ZIP, suite/street renumbered | Minor — suite change | Usually a within-building move or data cleanup, not a relocation. |
| ZIP+4 only | Minor | Postal refinement, not a change of location. |
An NPPES address change is the earliest public signal of a move — not proof of one. Providers update NPPES on their own timeline, and an address edit can lag or precede the physical move. Provider Signals surfaces the change and its date so your team can verify and act; we don't assert the provider has physically relocated.
How relocation detection works
CMS publishes a full-replacement NPPES file every week. Provider Signals ingests each release and diffs it against the prior snapshot — so instead of a static directory, you get the deltas: which providers' practice locations changed, from what to what, and when. Each relocation carries the old and new address, the provider's NPI, name, specialty, and the classification above.
- Before → after — the previous and current practice location, side by side.
- Scoped to your Watch — filter to the states, metros, ZIP radii, and specialties you sell to.
- Delivered your way — email alerts when a match posts, CSV export, or pull via API.
Filter relocations to your market
A relocation feed is only useful if it's targeted. Configure a Watch and slice by:
- Destination or origin state, metro (CBSA), ZIP radius, or county
- Specialty / taxonomy — cardiology, orthopedics, primary care, NPs, and 300+ more
- Individual providers (Type 1) vs. organizations (Type 2)
- Major moves only, or include minor address changes for data hygiene
Frequently asked questions
How do you detect a provider relocation?
We diff each weekly CMS NPPES full-replacement file against the previous one and flag providers whose practice location fields (address, city, state, ZIP, CBSA, county) changed. Each move includes the before and after values and the date it appeared.
What change counts as a "real" move versus noise?
A change of city, metro, or state is classified as a major relocation — a new employer or territory. A suite renumber or ZIP+4 refinement within the same city and ZIP is classified as minor. You choose whether to include minor changes, which are mainly useful for keeping records clean.
How fresh is the data?
CMS releases NPPES weekly; we ingest each release within about 48 hours, so relocations appear within days of posting. Growth Watches are refreshed weekly.
Can I limit relocations to my territory and specialties?
Yes. A Watch is a saved territory (state or metro) filtered to the specialties you care about. You'll only see moves into — or out of — the market you've configured.
