Ambulatory Care Pharmacist: how many are there, and how many are in private practice?

Ambulatory Care Pharmacists are licensed pharmacists with specialized expertise in integrated, accessible health care services, medication needs, sustained patient partnerships, and practice in family and community settings. This page shows the U.S. footprint of NPI records using NUCC taxonomy 1835P2201X as the primary classification, including the national total, state distribution, sole-proprietor reporting, and recent NPI enumeration patterns. It describes records, not a definitive count of individual clinicians or practices.

What this specialty covers

A licensed pharmacist who has demonstrated specialized knowledge and skill in the provision of integrated, accessible health care services by pharmacists and is accountable for addressing medication needs, developing sustained partnerships with patients, and practicing in the context of family and community.

Reading the sole-proprietor share

For this specialty, 873 of 3,469 active records, or 25.2%, carry the sole-proprietor flag in NPPES. This self-reported field is an imperfect proxy for private practice because it does not by itself establish ownership, employment status, or whether a pharmacist works within a larger organization.
