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 Obesity and Weight Management Nutrition Registered Dietitian. 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).

Kiera Sullivan, MS, RD, CNSC appears in the CMS NPPES registry as an Obesity and Weight Management Nutrition Registered Dietitian provider holding MS, RD, CNSC credentials at 1595 PACIFIC AVE APT 310, San Francisco, CA, 94109, with a listed phone of (510) 406-4100. NPI 1336920081 was issued on 10/09/2023.

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 Obesity and Weight Management Nutrition Registered Dietitian providers operate outside Part D entirely.

Obesity and Weight Management Nutrition Registered Dietitian is a narrow specialty nationwide, with 385 enrolled providers across 46 states, 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.
