XINKE CHEN, MD appears in the CMS NPPES registry as a General Practice Physician provider holding MD credentials at 770 MAGNOLIA AVE STE 2G, CORONA, CA, 92879, with a listed phone of (951) 907-5386. NPI 1780634857 was issued on 05/11/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHEN 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 7,163 prescription claims written by this provider, covering 225 Medicare beneficiaries and totaling roughly $672K in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 4.9%. 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 6.9662/100 for the 2023 performance year (Quality 0, Cost 23.2207), compared with the national average of 83.1.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 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.
