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).

LAUREN GROSSMAN, MD is a Integrative Medicine Physician provider practicing in MOUNTAIN VIEW, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1891771168. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

LAUREN GROSSMAN, MD appears in the CMS NPPES registry as a Integrative Medicine Physician provider holding MD credentials at 701 E EL CAMINO REAL, MOUNTAIN VIEW, CA, 94040, with a listed phone of (650) 934-7800. NPI 1891771168 was issued on 12/19/2005.

Medicare Part D records for calendar year 2023 show 232 prescription claims written by this provider, covering 167 Medicare beneficiaries and totaling roughly $4K in drug spend, split 10% brand-name and 90% generic by claim count.

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.
