How Duarte compares with the U.S.
Compared with the U.S. as a whole, Duarte has more clinicians in Internal Medicine - Hematology (621.0x), clinicians in Pathology - Hematology (334.8x) and clinicians in Surgery - Surgical Oncology (198.9x) per 100,000 residents.
Duarte has 5,820 active clinicians per 100,000 residents, compared with 2,198 for the U.S.
What these numbers mean
Clinicians per 100,000 residents compares places of different sizes. We count active clinicians who list a practice address in the area in the federal NPI registry (NPPES) and divide by the number of people who live there, according to the U.S. Census Bureau. The U.S. rate is the same calculation for the whole country.
A higher number does not mean it is easier to get an appointment, that wait times are shorter, or that care is better. It also does not show how many clinicians are accepting new patients or which insurance plans they take. A lower number does not by itself mean there is a shortage.
City counts use the city name in each clinician's practice address. That postal city can cover a larger or smaller area than the city limits the Census Bureau uses for population, and many clinicians list only one address even if they work in several places. Cities with hospitals or large medical centers often list more specialists than the number of residents alone would suggest, because patients also come from nearby areas.
96% of clinicians in Duarte listed in the CMS Medicare file (624 of 647) accept Medicare assignment. That is higher than the California share of 91%.
What is Medicare assignment?
A clinician who accepts Medicare assignment agrees to take the Medicare-approved amount as full payment for services that Original Medicare covers. You usually still pay your deductible and coinsurance. This comes from the CMS Doctors and Clinicians file and applies to Original Medicare only. Medicare Advantage plans have their own provider networks. It does not show whether a clinician is taking new patients.
Some clinicians are listed as "may accept assignment," which means they can decide case by case. Clinicians without an assignment flag, or who are not in the CMS file, are not counted as accepting assignment. That does not mean they refuse Medicare. Ask the office before your visit.
45% of clinicians in Duarte listed in the CMS Medicare file (290 of 647) have a CMS telehealth indicator, meaning their recent Medicare claims include telehealth services. That is higher than the California share of 28%.
About the telehealth indicator
The telehealth indicator comes from CMS. It marks clinicians whose recent paid Medicare claims include services delivered by telehealth. It means a clinician has provided some services by telehealth, not that every visit can be done online. A clinician without the indicator may still offer telehealth, for example to patients who are not on Medicare. Ask the office which visits can be done by video or phone.
These figures summarize public federal data. They do not measure quality of care, appointment availability, or whether a clinician accepts your insurance or new patients. Registry addresses can be out of date. Please confirm details directly with the office and your plan. This information is not medical advice.
