Doctors in Downey, CA
Active healthcare providers in Downey sourced from the CMS NPPES weekly file, no proprietary ratings, no editorial scores. NPI counts, specialty distribution, and primary practice addresses refreshed each release.
3,517 healthcare providers across 20 specialties
Downey, California appears in the CMS National Plan and Provider Enumeration System with 3,517 registered healthcare providers spanning 20 distinct NUCC-taxonomy specialties. This count includes every individual clinician who has applied for an NPI and listed a practice address in Downey - 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 Downey 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 2023 Medicare Part D data, and, according to CMS, can be searched, compared, and traced in our methodology.
The provider mix in Downey is weighted toward Behavior Technician (751 clinicians, followed by Pharmacist with 244 and Physical Therapist with 154). 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. Relative to California's population, Downey reports roughly 9 providers per 100,000 residents using the state-level denominator, which is a rough proxy rather than a precise access-to-care measurement; the true catchment area of any {cityName} clinician extends beyond the municipal boundary.
Within California, Downey ranks #58 of 805 cities tracked by provider count, accounting for 0.4% of the state's registered providers. Of California's most common specialties, Mental Health Counselor is the most prominent one with no provider currently listing a Downey practice address, a coverage gap Downey patients typically fill by traveling to a larger nearby hub.
For Downey patients, this directory is most useful as a starting shortlist, searching by specialty narrows the 690-taxonomy roster to clinicians with the relevant training, and each provider page links to NPI, state licensing boards, and the NPPES registry for credential verification. 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, so listing details may be out of date; call the practice directly to confirm the provider is still there, accepts your insurance, and is taking new patients. Nothing on this page substitutes for consulting a licensed clinician about your personal health decisions.
