RONALD NEWBOLD, MD appears in the CMS NPPES registry as a Diagnostic Radiology Physician provider holding MD credentials at 3501 N SCOTTSDALE RD, SCOTTSDALE, AZ, 85251, with a listed phone of (480) 425-5000. NPI 1861481806 was issued on 10/20/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NEWBOLD 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 231 prescription claims written by this provider, covering 205 Medicare beneficiaries and totaling roughly $1K in drug spend, split 29% brand-name and 71% 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.

Diagnostic Radiology Physician is a mid-sized specialty nationwide, with 39,474 enrolled providers across 56 states and an average of 63 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.
