The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

KAMAL ZAKKA, MD appears in the CMS NPPES registry as a Retina Specialist (Ophthalmology) Physician provider holding MD credentials at 9100 WILSHIRE BLVD STE 265E, BEVERLY HILLS, CA, 90212, with a listed phone of (800) 444-5241. NPI 1851914543 was issued on 05/28/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZAKKA 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 1,888 prescription claims written by this provider, covering 297 Medicare beneficiaries and totaling roughly $87K in drug spend. 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 90.7857/100 for the 2023 performance year (Quality 100, Cost 52.619), 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. 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.
