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).

BENJAMIN LING, DO is a Nephrology Physician provider practicing in MAYWOOD, Illinois, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: DO. NPI: 1790942142.

BENJAMIN LING, DO appears in the CMS NPPES registry as a Nephrology Physician provider holding DO credentials at 2160 S 1ST AVE, MAYWOOD, IL, 60153, with a listed phone of (708) 216-3306. NPI 1790942142 was issued on 05/21/2008.

Medicare Part D records for calendar year 2023 show 304 prescription claims written by this provider, covering 66 Medicare beneficiaries and totaling roughly $15K in drug spend, split 5% brand-name and 95% 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.
