NANCY WILLIAMS-WALLACE, M.D. appears in the CMS NPPES registry as a Pediatric Ophthalmology and Strabismus Specialist Physician provider holding M.D. credentials at 36422 US HIGHWAY 19 N, PALM HARBOR, FL, 34684, with a listed phone of (727) 772-7712. NPI 1184650970 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 WILLIAMS-WALLACE 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 43 prescription claims written by this provider, covering 17 Medicare beneficiaries and totaling roughly $5K in drug spend, split 26% brand-name and 74% 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.

Pediatric Ophthalmology and Strabismus Specialist Physician is a narrow specialty nationwide, with 242 enrolled providers across 40 states and an average of 266 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
