Physician and HCP data for 7.4M+ clinicians, matched by NPI and site

Dmand AI covers 7.4M+ HCPs with an active NPI. Among those with a US practice address are 1.2M+ physicians (MD and DO), 950K+ nurses, 334K+ pharmacists and 224K+ physician assistants. Counts as of October 23, 2026.

Yes. Every record starts from the NPI. Dmand AI begins with the CMS provider registry (NPPES) and Medicare enrollment records (PECOS), adds state licenses, Medicare Care Compare, Medicare Part B and Part D files, Open Payments, ClinicalTrials.gov, PubMed and certified health IT reporting, and joins them into one record per NPI. The registry itself lists practice addresses and phone numbers but no email addresses or mobile numbers.

Each clinician is linked to every site of care where they practice, and each link is labeled primary practice, employer or affiliated. Sites include hospitals, clinics, surgery centers, FQHCs, home health agencies and hospices, and each clinician’s medical groups are listed too. Every site sits under its medical group, parent organization and health system, so one physician opens the whole IDN in the Org Hierarchy Explorer.

Yes. Include or exclude any of 869 specialties, match secondary specialties, and narrow by state, city, ZIP code or practice site. Add sites of care, medical groups or a parent organization to keep only the physicians who work there. By primary specialty, Dmand AI has 35K+ cardiologists, 31K+ oncologists, 49K+ radiologists, 23K+ neurologists and 17K+ dermatologists in the US.

Yes. Clinical activity filters search Medicare procedure claims by CPT or HCPCS code across 7.5K+ codes, with annual volume, patients and claim year. A MedTech team can keep only the physicians who perform a procedure at the hospitals it sells to.

Yes. Prescription filters cover 7.9K+ drugs from Medicare Part D claims, by brand or generic, claim count and drug cost. Open Payments filters cover 3.1K+ paying manufacturers, by general or research payments and year, and each profile lists a clinician’s payments by manufacturer.

Yes. Technology filters search the EHR at a clinician’s practice by category, vendor and product, so a Health IT team can build a list of the physicians who work on the system it replaces or connects to. Each HCP profile shows the EHR at each of their sites.

Yes. Research filters search published research by title and keywords, clinical trials by NCT ID, condition, sponsor and status, and Open Payments research payments, so a pharma, biotech or CRO team can find the physicians already active in a therapeutic area and the sites where they practice.

Yes. Besides physicians, Dmand AI covers 2M+ behavioral health clinicians, 950K+ nurses with an NPI, including nurse practitioners, 547K+ physical and occupational therapists, 334K+ pharmacists, 292K+ dentists and dental staff and 224K+ physician assistants.

HCP records refresh every month. Each government source is picked up as it publishes: the NPI registry weekly with a full file each month, Care Compare monthly, Medicare enrollment quarterly, and Medicare utilization and Open Payments yearly. Contacts are checked when you request them, and you can ask for a fresh check at any time.
