EDWARD CHAN, MD appears in the CMS NPPES registry as a Dermatopathology Physician provider holding MD credentials at 101 CHESLEY DR, MEDIA, PA, 19063, with a listed phone of (610) 566-7111. NPI 1417940941 was issued on 08/30/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHAN 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 435 prescription claims written by this provider, covering 225 Medicare beneficiaries and totaling roughly $105K in drug spend, split 13% brand-name and 87% 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 85.9457/100 for the 2023 performance year (Quality 81.3723, Cost 76.78), compared with the national average of 83.1.

Dermatopathology Physician is a narrow specialty nationwide, with 570 enrolled providers across 48 states and an average of 650 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.
