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 Neonatal-Perinatal Medicine 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).

Kaitlyn Arbour, MD, MPH, MS appears in the CMS NPPES registry as a Neonatal-Perinatal Medicine Physician provider holding MD, MPH, MS credentials at 1540 E HOSPITAL DR SPC 4254, Ann Arbor, MI, 48109, with a listed phone of (734) 763-4109. NPI 1225666407 was issued on 04/01/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Arbour 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 Neonatal-Perinatal Medicine Physician providers operate outside Part D entirely.

Neonatal-Perinatal Medicine Physician is a mid-sized specialty nationwide, with 5,589 enrolled providers across 52 states and an average of 56 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.
