DAVID ENGEN, DDS, MSD appears in the CMS NPPES registry as a Orthodontics and Dentofacial Orthopedics Dentistry provider holding DDS, MSD credentials at 9911 N NEVADA ST STE 110, SPOKANE, WA, 99218, with a listed phone of (509) 326-4445. NPI 1659596948 was issued on 04/13/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ENGEN 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 457 prescription claims written by this provider, covering 152 Medicare beneficiaries and totaling roughly $3K in drug spend, with an opioid prescribing rate of 25.8%. 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.

Orthodontics and Dentofacial Orthopedics Dentistry is a mid-sized specialty nationwide, with 12,396 enrolled providers across 54 states and an average of 48 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
