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).

Mithran Sukumar, MD appears in the CMS NPPES registry as a Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician provider holding MD credentials at 3181 SW SAM JACKSON PARK RD, Portland, OR, 97239, with a listed phone of (503) 494-7820. NPI 1134134646 was issued on 07/31/2006.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 97.8/100 for the 2023 performance year (Quality 81), compared with the 83.5 average among clinicians with a measured score.

Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician is a mid-sized specialty nationwide, with 5,070 enrolled providers across 52 states and an average of 128 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.
