NADEEM VAIDYA, M.D. appears in the CMS NPPES registry as a Retina Specialist (Ophthalmology) Physician provider holding M.D. credentials at 16100 SAND CANYON AVE STE 385, IRVINE, CA, 92618, with a listed phone of (949) 732-0201. NPI 1578616520 was issued on 01/20/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what VAIDYA 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 186 prescription claims written by this provider, covering 65 Medicare beneficiaries and totaling roughly $15K in drug spend, split 34% brand-name and 66% 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 75.25/100 for the 2023 performance year (Quality 55), compared with the national average of 83.1.

Retina Specialist (Ophthalmology) Physician is a narrow specialty nationwide, with 913 enrolled providers across 48 states and an average of 558 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
