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).

BRYAN LAO, MD is a Psychosomatic Medicine Physician provider practicing in LOS ANGELES, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1558823021. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

BRYAN LAO, MD appears in the CMS NPPES registry as a Psychosomatic Medicine Physician provider holding MD credentials at 300 UCLA MEDICAL PLZ STE 2200, LOS ANGELES, CA, 90095, with a listed phone of (310) 825-9989. NPI 1558823021 was issued on 04/03/2019.

Medicare Part D records for calendar year 2023 show 393 prescription claims written by this provider, covering 34 Medicare beneficiaries and totaling roughly $69K in drug spend, split 7% brand-name and 93% generic by claim count.

Psychosomatic Medicine Physician is a narrow specialty nationwide, with 491 enrolled providers across 43 states and an average of 645 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.
