Board certification
Not published by CMS
CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Sports Medicine Podiatrist. Verify directly:
How MIPS and board certification work
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).
Marshall Shieh, DPM appears in the CMS NPPES registry as a Sports Medicine Podiatrist provider holding DPM credentials at 3545 SAN DIMAS ST, Bakersfield, CA, 93301, with a listed phone of (661) 327-2101. NPI 1407097272 was issued on 03/09/2009.
Medicare Part D records for calendar year 2023 show 520 prescription claims written by this provider, covering 236 Medicare beneficiaries and totaling roughly $20K in drug spend, split 6% brand-name and 94% generic by claim count, with an opioid prescribing rate of 5.6%.
Sports Medicine Podiatrist is a narrow specialty nationwide, with 135 enrolled providers across 30 states and an average of 253 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.
