KOEN ELSWICK, OD appears in the CMS NPPES registry as a Optometrist provider holding OD credentials at 340 W MAIN ST, ABINGDON, VA, 24210, with a listed phone of (276) 628-3118. NPI 1326785163 was issued on 05/13/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ELSWICK 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 123 prescription claims written by this provider, covering 69 Medicare beneficiaries and totaling roughly $10K in drug spend, split 21% brand-name and 79% 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 89.1529/100 for the 2023 performance year (Quality 100, Cost 63.843), compared with the national average of 83.1.

Optometrist is a high-volume specialty nationwide, with 60,463 enrolled providers across 56 states and an average of 257 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
