HAN XIAO, MD appears in the CMS NPPES registry as a Medical Oncology Physician provider holding MD credentials at 136 MOUNTAIN VIEW BLVD, BASKING RIDGE, NJ, 07920, with a listed phone of (908) 542-3300. NPI 1194705533 was issued on 01/20/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what XIAO 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 1,536 prescription claims written by this provider, covering 193 Medicare beneficiaries and totaling roughly $4.2 million in drug spend, with an opioid prescribing rate of 1.2%. 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 92.9172/100 for the 2023 performance year (Quality 88.1758), compared with the national average of 83.1.

Medical Oncology Physician is a narrow specialty nationwide, with 3,792 enrolled providers across 53 states and an average of 689 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.
