BO ZHAO, MD appears in the CMS NPPES registry as a Hematology & Oncology Physician provider holding MD credentials at 500 SENTARA CIR STE 203, WILLIAMSBURG, VA, 23188, with a listed phone of (757) 229-2236. NPI 1245464742 was issued on 05/12/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZHAO 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 1,382 prescription claims written by this provider, covering 203 Medicare beneficiaries and totaling roughly $3.1 million in drug spend, with an opioid prescribing rate of 6.5%. 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 79.1641/100 for the 2023 performance year (Quality 66.2144), compared with the national average of 83.1.

Hematology & Oncology Physician is a mid-sized specialty nationwide, with 11,215 enrolled providers across 54 states and an average of 847 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.
