ARTHUR SIEGEL, M.D. appears in the CMS NPPES registry as a Adolescent Medicine (Internal Medicine) Physician provider holding M.D. credentials at 195 1ST AVE W, NEWARK, NJ, 07107, with a listed phone of (973) 483-5551. NPI 1912121534 was issued on 04/13/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SIEGEL 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 14 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $116 in drug spend. 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.

Adolescent Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 377 enrolled providers across 46 states and an average of 3,242 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.
