DAVID JANG, MD appears in the CMS NPPES registry as a Otolaryngology Physician provider holding MD credentials at 40 DUKE MEDICINE CIR, DURHAM, NC, 27710, with a listed phone of (919) 684-8111. NPI 1295995355 was issued on 06/12/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JANG 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 236 prescription claims written by this provider, covering 98 Medicare beneficiaries and totaling roughly $107K in drug spend, split 12% brand-name and 88% generic by claim count. 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.

Otolaryngology Physician is a mid-sized specialty nationwide, with 10,895 enrolled providers across 54 states and an average of 509 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.
