| Ambulatory and specialty care | 266K+ |

## Dmand AI links clinicians to the sites where they practice, leaders to the hospitals they run and hospitals to their parent organizations

Each link comes from a record that ties a person or site to another, such as a practice location filed with CMS, a Medicare billing reassignment or an ownership filing. 989K+ physicians are linked to a site of care or medical group, and 457K+ sites of care are tied to a medical group.

- 6.4M+ clinician links to sites of care
- 2.1M+ clinicians linked to a medical group
- 150K+ leaders placed at a hospital
- 99% hospitals placed under a parent

## Dmand AI records refresh every month, and a published count changes on every page at the same time

The counts on this page are the figures every Dmand AI page uses. When a new set is adopted, the site, the profiles and the directories change together, so no page carries an older number.

### Counted from records, not estimated

Each figure is a count of Dmand AI’s own records on a stated date, not a survey estimate or a projection.

### Rounded down, never up

Published counts round down to the nearest thousand or hundred thousand, so a figure never claims more records than exist.

### Refreshed monthly, checked on request

HCP, executive and site records refresh every month as public sources publish and Dmand AI’s own data updates. Contacts are checked when you ask for them.

## Healthcare data coverage FAQs

### How many doctors are there in the US?

Dmand AI counts 1.2M+ physicians (MD and DO) with an active NPI and a US practice address, as of October 25, 2026. The count includes every active physician NPI, such as physicians in research, administration or part-time practice, so it runs higher than workforce surveys that count only physicians in active patient care.

### How many nurses are there in the US?

Dmand AI counts 950K+ nurses who hold their own NPI: nurse practitioners, nurse anesthetists, and registered and practical nurses who bill or prescribe under their own number. Most staff nurses never apply for an NPI, so this is not a count of every working nurse. Count as of October 25, 2026.

### How many healthcare providers are in the US?

Dmand AI counts 7.4M+ HCPs with an active NPI, from physicians and nurses to therapists, pharmacists and behavioral health clinicians. It does not count healthcare workers without an NPI, such as most hospital staff, so employment counts from the Bureau of Labor Statistics run higher. Count as of October 25, 2026.

### How many pharmacists, dentists and physician assistants are in the US?

Among clinicians with an active NPI and a US practice address, Dmand AI counts 334K+ pharmacists, 292K+ dentists and dental staff, and 224K+ physician assistants, as of October 25, 2026.

### How many healthcare facilities are in the US?

Dmand AI maps 997K+ sites of care, counting each unique location once: 290K+ primary and community care sites, 266K+ ambulatory and specialty care sites, 114K+ dental and eye care sites, 105K+ behavioral health sites, 90K+ pharmacies and 81K+ post-acute and long-term care sites, plus hospitals and their outpatient departments. Hospital counts by type are on the hospital and health system data page.

### How many medical practices and medical groups are in the US?

Dmand AI counts 181K+ medical groups with two or more clinicians and 235K+ solo practices. Two-thirds of the groups have two to five practitioners, and 6.2K+ have more than 100. Group counts as of October 25, 2026.

### How many urgent care centers, surgery centers and FQHCs are in the US?

Dmand AI counts 18.9K+ federally qualified health center (FQHC) sites, 13.4K+ urgent care sites and 12.1K+ surgery centers, each as a unique location, as of October 25, 2026.

### How many nursing homes and home health agencies are in the US?

Dmand AI counts 14.7K+ skilled nursing facilities, 14.4K+ home health agency offices and 9K+ hospice offices. They sit within 81K+ post-acute and long-term care sites, which also include senior living communities and facilities for people with intellectual and developmental disabilities.

### How many pharmacies are in the US?

Dmand AI counts 90K+ pharmacies: retail and chain stores, independent pharmacies, and specialty, long-term care, compounding, hospital, mail-order and home infusion pharmacies.

### What counts as one record in Dmand AI?

One HCP is one clinician with an active individual NPI. One hospital is one facility with its own CCN. One site of care is one unique location. One medical group is a practice of two or more clinicians billing under one organization. One executive is one person in a leadership or non-clinical role at a US healthcare organization. The table under Coverage lists every definition.

### Why do Dmand AI’s counts differ from other sources?

Sources count different things. Workforce surveys count people in active practice, registries count everyone who holds an identifier, and hospital lists differ on whether outpatient departments, campuses and units count as hospitals. Dmand AI states the definition next to every count, so you can compare like with like.

### How often are these counts updated?

Records refresh every month. The published counts change on every Dmand AI page on the same day when a new set is adopted, and each count on this page carries the date it was taken.
