NANCY DAVIS, O.D. appears in the CMS NPPES registry as a Vision Therapy Optometrist provider holding O.D. credentials at 361 W SOUTHLAKE BLVD STE 100, SOUTHLAKE, TX, 76092, with a listed phone of (817) 491-4994. NPI 1558474726 was issued on 08/15/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DAVIS 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 88 prescription claims written by this provider, covering 39 Medicare beneficiaries and totaling roughly $17K in drug spend, split 58% brand-name and 42% 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 0/100 for the 2023 performance year (Quality 0), compared with the national average of 83.1.

Vision Therapy Optometrist is a narrow specialty nationwide, with 369 enrolled providers across 42 states and an average of 209 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.
