JULIANA IONESCU, FNP appears in the CMS NPPES registry as a Oncology Registered Nurse provider holding FNP credentials at 12442 SW SCHOLLS FERRY RD STE 206, TIGARD, OR, 97223, with a listed phone of (503) 216-9200. NPI 1306551361 was issued on 01/13/2023. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what IONESCU 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 557 prescription claims written by this provider, covering 310 Medicare beneficiaries and totaling roughly $41K in drug spend, with an opioid prescribing rate of 5.0%. 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.

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.
