JOHN MANDEVILLE, M.D., PHD appears in the CMS NPPES registry as a Ophthalmic Plastic and Reconstructive Surgery Physician provider holding M.D., PHD credentials at 97 LIBBEY INDUSTRIAL PKWY STE 100, EAST WEYMOUTH, MA, 02189, with a listed phone of (781) 331-3300. NPI 1811986060 was issued on 10/20/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MANDEVILLE 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 1,816 prescription claims written by this provider, covering 731 Medicare beneficiaries and totaling roughly $21K in drug spend, split 7% brand-name and 93% 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.

Ophthalmic Plastic and Reconstructive Surgery Physician is a narrow specialty nationwide, with 291 enrolled providers across 46 states and an average of 624 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.
