ALEXANDRA ARNIERI, PA-C appears in the CMS NPPES registry as a Oncology Clinical Nurse Specialist provider holding PA-C credentials at 1900 N HIGLEY ROAD, GILBERT, AZ, 85234, with a listed phone of (480) 543-2000. NPI 1023607975 was issued on 01/14/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ARNIERI 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 53 prescription claims written by this provider, covering 22 Medicare beneficiaries and totaling roughly $536 in drug spend, with an opioid prescribing rate of 24.5%. 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 81.4923/100 for the 2023 performance year, compared with the national average of 83.1.

Oncology Clinical Nurse Specialist is a narrow specialty nationwide, with 209 enrolled providers across 38 states and an average of 435 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
