Find new providers before your competitors do
A clinician who has just registered an NPI has not yet chosen an EMR, a billing service, a lab, or a malpractice carrier. That window is short and it is visible in public data.
Why registration date matters
Every provider who bills insurance in the United States needs an NPI, and CMS records the ' + date it was issued. For a clinician entering practice, that date is the closest public signal there is to the start of a buying cycle. Nothing else in healthcare is both this current and this complete.
What you get
Name, NPI, credential, primary and secondary taxonomies, practice address, phone and fax, and whether they registered as a sole proprietor — which is a useful proxy for whether they are buying for themselves or for an employer.
How people use it
Weekly pull of new registrations inside a sales territory. A radius around each rep's base. Filtering to sole proprietors when the product suits independent practices, or to large group affiliations when it does not.
What this data will not tell you
An enumeration date is when an NPI was issued, not when someone started practising. Residents often register years before they finish training, and a provider changing employers keeps the same NPI, so they will not appear as new. Treat this as a prospect signal to qualify, not a verified start date.
