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).

ANNE MAXWELL, M.D. is a Otology & Neurotology Physician provider practicing in LOMA LINDA, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D..

ANNE MAXWELL, M.D. appears in the CMS NPPES registry as a Otology & Neurotology Physician provider holding M.D. credentials at 11370 ANDERSON ST STE 2100, LOMA LINDA, CA, 92354, with a listed phone of (909) 558-7884. NPI 1164765814 was issued on 04/01/2013.

Medicare Part D records for calendar year 2023 show 90 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $4K 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.
