ESTELLE ZANDSTRA, DDS appears in the CMS NPPES registry as a Prosthodontics provider holding DDS credentials at 3400-C OLD MILTON PARKWAY, ALPHARETTA, GA, 30005, with a listed phone of (770) 410-4999. NPI 1164537403 was issued on 08/19/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZANDSTRA 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 28 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $195 in drug spend. 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.

Prosthodontics is a narrow specialty nationwide, with 3,510 enrolled providers across 51 states and an average of 85 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.
