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 Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician. Verify directly:

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).

Michael Bowdish, M.D. appears in the CMS NPPES registry as a Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician provider holding M.D. credentials at 127 S SAN VICENTE BLVD # A3600, Los Angeles, CA, 90048, with a listed phone of (310) 423-3851. NPI 1992988422 was issued on 12/06/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Bowdish most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

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.

Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician is a mid-sized specialty nationwide, with 5,062 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.
