JAY WALKO, RN, MSN, AGPCNP-C appears in the CMS NPPES registry as a Critical Care Medicine Registered Nurse provider holding RN, MSN, AGPCNP-C credentials at 17727 E BURNSIDE ST, PORTLAND, OR, 97233, with a listed phone of (503) 215-9800. NPI 1558879502 was issued on 01/11/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what WALKO 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 2,685 prescription claims written by this provider, covering 102 Medicare beneficiaries and totaling roughly $188K in drug spend, split 17% brand-name and 83% generic by claim count, with an opioid prescribing rate of 6.1%. 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.

Critical Care Medicine Registered Nurse is a mid-sized specialty nationwide, with 6,529 enrolled providers across 53 states and an average of 752 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.
