DAVID JENG, M.D. appears in the CMS NPPES registry as a Ophthalmology Physician provider holding M.D. credentials at 1013 FARMINGTON AVENUE, WEST HARTFORD, CT, 06107, with a listed phone of (860) 233-2020. NPI 1679758742 was issued on 01/08/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JENG 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 3,780 prescription claims written by this provider, covering 749 Medicare beneficiaries and totaling roughly $1.2 million in drug spend, split 53% brand-name and 47% 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 75.4453/100 for the 2023 performance year (Quality 76.416, Cost 28.186), compared with the national average of 83.1.

Ophthalmology Physician is a mid-sized specialty nationwide, with 22,090 enrolled providers across 56 states and an average of 1,420 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.
