Zuoliang Xiao, M.D. appears in the CMS NPPES registry as a Gastroenterology Physician provider holding M.D. credentials at 4360 FULTON DR NW STE B, Canton, OH, 44718, with a listed phone of (330) 305-2020. NPI 1104149202 was issued on 03/04/2010. 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 877 prescription claims written by this provider, covering 310 Medicare beneficiaries and totaling roughly $565K in drug spend, split 15% brand-name and 85% 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 95.5/100 for the 2023 performance year (Quality 100, Cost 85.1), compared with the national average of 83.1.

Gastroenterology Physician is a mid-sized specialty nationwide, with 16,567 enrolled providers across 54 states and an average of 833 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
