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.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

SUNG LEE, D.O. is a Interventional Cardiology Physician provider practicing in MERCED, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: D.O.. NPI: 1558757484. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

SUNG LEE, D.O. appears in the CMS NPPES registry as a Interventional Cardiology Physician provider holding D.O. credentials at 315 MERCY AVE STE 400, MERCED, CA, 95340, with a listed phone of (209) 564-3700. NPI 1558757484 was issued on 04/07/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LEE 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 97 prescription claims written by this provider, covering 15 Medicare beneficiaries and totaling roughly $15K in drug spend, split 16% brand-name and 84% generic by claim count.

Interventional Cardiology Physician is a narrow specialty nationwide, with 3,382 enrolled providers across 53 states and an average of 2,984 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.
