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).

PATRICIA LOPEZ-GUTIERREZ, MD is a Obstetrics Physician provider practicing in ROUND ROCK, Texas, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1659570208. 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.

PATRICIA LOPEZ-GUTIERREZ, MD appears in the CMS NPPES registry as a Obstetrics Physician provider holding MD credentials at 425 UNIVERSITY BLVD, ROUND ROCK, TX, 78665, with a listed phone of (512) 509-0200. NPI 1659570208 was issued on 07/13/2007.

Medicare Part D records for calendar year 2023 show 1,815 prescription claims written by this provider, covering 226 Medicare beneficiaries and totaling roughly $112K 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.

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.
