KATHRYN GUIDONE, APRN appears in the CMS NPPES registry as a Pediatric Registered Nurse provider holding APRN credentials at 550 1ST AVE, NEW YORK, NY, 10016, with a listed phone of (212) 263-5800. NPI 1427784693 was issued on 07/28/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GUIDONE 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 421 prescription claims written by this provider, covering 168 Medicare beneficiaries and totaling roughly $396K in drug spend, split 69% brand-name and 31% generic by claim count, with an opioid prescribing rate of 7.6%. 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 84.4744/100 for the 2023 performance year (Quality 93.334, Cost 54.914), compared with the national average of 83.1.

Pediatric Registered Nurse is a narrow specialty nationwide, with 2,899 enrolled providers across 52 states and an average of 748 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.
