ELIZABETH O'NEILL, MD MPH appears in the CMS NPPES registry as a Plastic Surgery Physician provider holding MD MPH credentials at 1620 W HARRISON ST, CHICAGO, IL, 60612, with a listed phone of (610) 704-5060. NPI 1891317160 was issued on 05/10/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what O'NEILL 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 35 prescription claims written by this provider, covering 14 Medicare beneficiaries and totaling roughly $671 in drug spend, with an opioid prescribing rate of 37.1%. 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.

Plastic Surgery Physician is a mid-sized specialty nationwide, with 5,316 enrolled providers across 52 states and an average of 84 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.
