MELISSA CARDENAS, FNP-C appears in the CMS NPPES registry as a Oncology Registered Nurse provider holding FNP-C credentials at 10515 W SANTA FE DR, SUN CITY, AZ, 85351, with a listed phone of (623) 832-6530. NPI 1982103586 was issued on 02/08/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CARDENAS 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 1,285 prescription claims written by this provider, covering 352 Medicare beneficiaries and totaling roughly $71K 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 98.3273/100 for the 2023 performance year, compared with the national average of 83.1.

Oncology Registered Nurse is a narrow specialty nationwide, with 857 enrolled providers across 50 states and an average of 555 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.
