Natasha Demattos, M.D. appears in the CMS NPPES registry as a Neurology Physician provider holding M.D. credentials at 1212 N PINES RD, Spokane Valley, WA, 99206, with a listed phone of (509) 893-8140. NPI 1922217678 was issued on 05/21/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Demattos 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 2,851 prescription claims written by this provider, covering 292 Medicare beneficiaries and totaling roughly $1.0 million in drug spend, split 15% brand-name and 85% 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.

Neurology Physician is a mid-sized specialty nationwide, with 19,866 enrolled providers across 54 states and an average of 1,309 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
