GREGORY ARNONE, MD appears in the CMS NPPES registry as a Neurological Surgery Physician provider holding MD credentials at 423 NORTH 21ST STREET, CAMP HILL, PA, 17011, with a listed phone of (717) 763-2771. NPI 1356630503 was issued on 03/28/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ARNONE 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 36 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $226 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 71.1774/100 for the 2023 performance year (Quality 46.0539, Cost 58.7042), compared with the national average of 83.1.

Neurological Surgery Physician is a mid-sized specialty nationwide, with 8,100 enrolled providers across 53 states and an average of 181 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.
