JEFFREY JUANLU, D.O. appears in the CMS NPPES registry as a Hospitalist Physician provider holding D.O. credentials at 355 DARDANELLI LN, LOS GATOS, CA, 95032, with a listed phone of (408) 866-4036. NPI 1922286418 was issued on 02/06/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JUANLU most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 429 prescription claims written by this provider, covering 110 Medicare beneficiaries and totaling roughly $26K in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 11.0%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Hospitalist Physician is a mid-sized specialty nationwide, with 16,825 enrolled providers across 54 states and an average of 888 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
