MARGIE NIELSEN, DNP, FNP-BC appears in the CMS NPPES registry as a Pediatric Nurse Practitioner provider holding DNP, FNP-BC credentials at 15950 SW MILLIKAN WAY, BEAVERTON, OR, 97003, with a listed phone of (503) 646-0161. NPI 1124557715 was issued on 06/07/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what NIELSEN 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 2,843 prescription claims written by this provider, covering 379 Medicare beneficiaries and totaling roughly $283K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 3.7%. 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.

Pediatric Nurse Practitioner is a mid-sized specialty nationwide, with 21,082 enrolled providers across 52 states and an average of 312 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
