MARGUERITE BILLBROUGH, MD appears in the CMS NPPES registry as a Glaucoma Specialist (Ophthalmology) Physician provider holding MD credentials at 1098 W BALTIMORE PIKE STE 3301, MEDIA, PA, 19063, with a listed phone of (610) 522-2822. NPI 1154398782 was issued on 03/02/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BILLBROUGH 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 1,266 prescription claims written by this provider, covering 376 Medicare beneficiaries and totaling roughly $748K in drug spend, split 64% brand-name and 36% 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 73.2255/100 for the 2023 performance year (Quality 96.369, Cost 32.716), compared with the national average of 83.1.

Glaucoma Specialist (Ophthalmology) Physician is a narrow specialty nationwide, with 354 enrolled providers across 42 states and an average of 2,962 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.
