COLIN BACORN, MD appears in the CMS NPPES registry as a Ophthalmology Physician provider holding MD credentials at 835 THIRD AVE, CHULA VISTA, CA, 91911, with a listed phone of (619) 425-7755. NPI 1932640109 was issued on 03/20/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BACORN 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 429 prescription claims written by this provider, covering 257 Medicare beneficiaries and totaling roughly $12K in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 24.5%. 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 74.3962/100 for the 2023 performance year (Quality 64.7185, Cost 52.4354), 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. 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.
