How to read this directory

Rsm, California appears in the CMS National Plan and Provider Enumeration System with 11 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 Rsm - 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 Rsm 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 Rsm is weighted toward Registered Dietitian (2 clinicians, followed by Acute Care Nurse Practitioner with 1 and Speech-Language Pathologist 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 Rsm practice address, a coverage gap Rsm patients typically fill by traveling to a larger nearby hub.

For Rsm 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.
