Board certification
Not published by CMS
CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Emergency Medicine Physician. Verify directly:
How MIPS and board certification work
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).
Enrique Zarate, MD appears in the CMS NPPES registry as an Emergency Medicine Physician provider holding MD credentials at 130 W 11TH ST STE D, Tracy, CA, 95376, with a listed phone of (209) 832-9178. NPI 1417939851 was issued on 11/18/2005.
Medicare Part D records for calendar year 2023 show 2,279 prescription claims written by this provider, covering 177 Medicare beneficiaries and totaling roughly $461K in drug spend, split 16% brand-name and 82% generic by claim count, with an opioid prescribing rate of 1.3%.
Emergency Medicine Physician is a high-volume specialty nationwide, with 64,463 enrolled providers across 56 states and an average of 352 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.
