How to read this directory
Castaner, Puerto Rico appears in the CMS National Plan and Provider Enumeration System with 12 registered healthcare providers spanning 6 distinct NUCC-taxonomy specialties. This count includes every individual clinician who has applied for an NPI and listed a practice address in Castaner - 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 Castaner 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 Castaner is weighted toward Family Medicine Physician (4 clinicians, followed by General Practice Physician with 2 and Clinical Social Worker with 2). 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 Puerto Rico's population, Castaner reports roughly 0.4 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.
Of Puerto Rico's most common specialties, Pharmacist is the most prominent one with no provider currently listing a Castaner practice address, a coverage gap Castaner patients typically fill by traveling to a larger nearby hub.

Important: PlainDoctor is a directory of publicly available CMS government data, not a review site, a ranking, or medical advice.
