LAURIE MARZELL, N.D. appears in the CMS NPPES registry as a Naturopath provider holding N.D. credentials at 15962 BOONES FERRY RD STE 204, LAKE OSWEGO, OR, 97035, with a listed phone of (503) 655-9493. NPI 1811036700 was issued on 02/06/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARZELL 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 349 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $50K in drug spend, split 23% brand-name and 77% generic by claim count. 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.

Naturopath is a mid-sized specialty nationwide, with 6,661 enrolled providers across 53 states and an average of 120 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.
