MAYLENE XIE appears in the CMS NPPES registry as a Allergy & Immunology Physician provider at 433 HACKENSACK AVE STE 204, HACKENSACK, NJ, 07601, with a listed phone of (201) 883-1062. NPI 1891157384 was issued on 03/23/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what XIE 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 1,072 prescription claims written by this provider, covering 284 Medicare beneficiaries and totaling roughly $324K in drug spend, split 30% brand-name and 70% 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 91.2882/100 for the 2023 performance year (Quality 84.1603), compared with the national average of 83.1.

Allergy & Immunology Physician is a narrow specialty nationwide, with 3,390 enrolled providers across 52 states and an average of 764 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.
