Patrick Chapman, N.D. appears in the CMS NPPES registry as a Naturopath provider holding N.D. credentials at 2002 SE 50TH AVE, Portland, OR, 97215, with a listed phone of (503) 640-4012. NPI 1417983255 was issued on 06/23/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Chapman 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 30 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $10K in drug spend, split 50% brand-name and 50% 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.
