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).

Bertrand Liang, MD appears in the CMS NPPES registry as a Neurology Physician provider holding MD credentials at 13638 FIFE CT, Colorado Springs, CO, 80921, with a listed phone of (858) 603-5963. NPI 1396010856 was issued on 03/16/2012.

Medicare Part D records for calendar year 2023 show 59 prescription claims written by this provider, covering 15 Medicare beneficiaries and totaling roughly $24K in drug spend, split 24% brand-name and 76% generic by claim count.

Neurology Physician is a mid-sized specialty nationwide, with 19,866 enrolled providers across 54 states and an average of 1,309 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.
