KELLY O'BRIEN, ARNP appears in the CMS NPPES registry as a Case Management Registered Nurse provider holding ARNP credentials at 4663 AUTUMNDALE DR, PACE, FL, 32571, with a listed phone of (850) 776-3325. NPI 1124614789 was issued on 12/17/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what O'BRIEN 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 338 prescription claims written by this provider, covering 64 Medicare beneficiaries and totaling roughly $25K 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.

Case Management Registered Nurse is a mid-sized specialty nationwide, with 5,464 enrolled providers across 53 states and an average of 1,066 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.
