How to read this directory

Boonville, California appears in the CMS National Plan and Provider Enumeration System with 12 registered healthcare providers spanning 10 distinct NUCC-taxonomy specialties. This count includes every individual clinician who has applied for an NPI and listed a practice address in Boonville - physicians, dentists, nurse practitioners, physician assistants, chiropractors, physical therapists, optometrists, psychologists, podiatrists, and every other credentialed provider type CMS tracks. It does not measure hospital beds, urgent-care capacity, or whether a given clinic is accepting new patients; it measures the pool of professionals with current NPI enrollment and a Boonville practice location on file. Every figure is drawn from the federal National Provider Identifier Registry (CMS NPPES) - more than 7 million providers, maintained since May 2007, with 2024 Medicare Part D data, and, according to CMS, can be searched, compared, and traced in our methodology.

The provider mix in Boonville is weighted toward Family Medicine Physician (3 clinicians, followed by Nurse Practitioner with 1 and Driver with 1). That distribution reflects how NPPES records specialty: providers self-select a primary taxonomy code, so a family physician who also practices geriatrics will show up under whichever NUCC code they registered first. Per-capita density calculations require a state population baseline, which is currently unavailable for this geography.

Of California's most common specialties, Behavior Technician is the most prominent one with no provider currently listing a Boonville practice address, a coverage gap Boonville patients typically fill by traveling to a larger nearby hub.

For Boonville patients, this directory is most useful as a starting shortlist. Important: PlainDoctor is a directory of publicly available CMS government data, not a review site, a ranking, or medical advice. NPPES data is self-reported and refreshed monthly; call the practice directly to confirm the provider is still there, accepts your insurance, and is taking new patients.
