Workforce

New doctors and clinicians

524,852 clinicians registered a new NPI from Nov 2025 to Oct 2026, 4% more than the 12 months before. The busiest month was April.

Every clinician who bills or prescribes needs a National Provider Identifier (NPI). New NPIs mostly belong to people entering practice: new nurse practitioners, therapists, counselors and other clinicians, and doctors starting residency. Residents usually register as students, so few new NPIs are listed under a physician specialty at first.

About this page

Track new doctors and clinicians entering practice in the United States. Every clinician who bills or prescribes needs a National Provider Identifier (NPI). So new NPI registrations show who joins the workforce each month: new nurse practitioners, therapists and counselors, physicians starting residency, and clinicians moving to the U.S.

How to read new doctors data

A new NPI usually marks the start of training or practice. For example, most new physicians register when they begin residency. However, some clinicians register before they start work, and a few never practice. Therefore, read the numbers as a sign of growth, not an exact headcount.

In addition, states with fast-growing populations or large training programs tend to add more new clinicians. As a result, a high share can reflect new residents as well as new practices.

About the data

Registrations come from the monthly CMS NPPES files (opens in a new tab). From December 2026, the page also tracks clinicians moving between states. Related: what an NPI number is, specialties, doctors per capita.

Questions about new doctors

When do most new doctors register? Many new physicians get an NPI shortly before residency starts in July. As a result, the monthly trend shows a seasonal rise. In contrast, nurse practitioners and counselors register throughout the year.

Does a new NPI mean a new doctor in my area? Usually it means a clinician is starting work or training there. However, some register at a school or employer address and then move. So the state numbers are a good guide, while single counties can vary.

Can I see new doctors by specialty? Yes. The table lists the specialties new clinicians registered in over the last year, largest first.
