ANA-IRINA SPRINGER, RNFA, ARNP appears in the CMS NPPES registry as a Registered Nurse First Assistant provider holding RNFA, ARNP credentials at 11911 NE 132ND ST, KIRKLAND, WA, 98034, with a listed phone of (425) 899-5800. NPI 1619599040 was issued on 05/07/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SPRINGER 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 859 prescription claims written by this provider, covering 299 Medicare beneficiaries and totaling roughly $100K in drug spend, split 17% brand-name and 83% generic by claim count, with an opioid prescribing rate of 3.3%. 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.

Registered Nurse First Assistant is a narrow specialty nationwide, with 2,649 enrolled providers across 50 states and an average of 419 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
