GEORGE GUIRGUIS, DO, FACOG appears in the CMS NPPES registry as a Maternal & Fetal Medicine Physician provider holding DO, FACOG credentials at 174 LILY POND AVE FL 2, STATEN ISLAND, NY, 10305, with a listed phone of (833) 732-1131. NPI 1407087711 was issued on 08/04/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GUIRGUIS 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Maternal & Fetal Medicine Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 96.566/100 for the 2023 performance year, compared with the national average of 83.1.

Maternal & Fetal Medicine Physician is a narrow specialty nationwide, with 2,103 enrolled providers across 52 states and an average of 75 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.
