DA XU, PA-C appears in the CMS NPPES registry as a Physician Assistant provider holding PA-C credentials at 8001 MADISON AVE, CITRUS HEIGHTS, CA, 95610, with a listed phone of (916) 984-7890. NPI 1366755381 was issued on 07/19/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what XU 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 1,021 prescription claims written by this provider, covering 441 Medicare beneficiaries and totaling roughly $66K in drug spend, split 9% brand-name and 91% generic by claim count, with an opioid prescribing rate of 9.3%. 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 96.5085/100 for the 2023 performance year (Quality 80.342), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 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.
