CHENCHEN COSTELLOE appears in the CMS NPPES registry as a Anesthesiology Physician provider at 3300 GALLOWS RD, FALLS CHURCH, VA, 22042, with a listed phone of (703) 776-3138. NPI 1801241013 was issued on 04/26/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what COSTELLOE 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 162 prescription claims written by this provider, covering 59 Medicare beneficiaries and totaling roughly $7K in drug spend, with an opioid prescribing rate of 24.1%. 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.

Anesthesiology Physician is a high-volume specialty nationwide, with 56,398 enrolled providers across 56 states and an average of 860 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.
