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).

IAN CHOW, MD appears in the CMS NPPES registry as a Surgery of the Hand (Plastic Surgery) Physician provider holding MD credentials at 8501 HARCOURT RD, INDIANAPOLIS, IN, 46260, with a listed phone of (317) 875-9105. NPI 1275922858 was issued on 01/20/2015.

Medicare Part D records for calendar year 2023 show 96 prescription claims written by this provider, covering 72 Medicare beneficiaries and totaling roughly $657 in drug spend, with an opioid prescribing rate of 70.8%.

Surgery of the Hand (Plastic Surgery) Physician is a narrow specialty nationwide, with 370 enrolled providers across 43 states and an average of 106 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.
