Specialty board-certified rate — Pediatric Nutrition Registered Dietitian estimate
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus Maintenance of Certification cycles. CMS does not publish a per-provider board-certification field; the figure shown is the specialty-level estimated rate from ABMS / AOA reference data.
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).
CHAD HETHERWICK, MS, RDN appears in the CMS NPPES registry as a Pediatric Nutrition Registered Dietitian provider holding MS, RDN credentials at 8508 N PRAIRIE VW, PRESCOTT VALLEY, AZ, 86315, with a listed phone of (928) 772-8652. NPI 1104023969 was issued on 06/27/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HETHERWICK 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 Pediatric Nutrition Registered Dietitian providers operate outside Part D entirely.
Pediatric Nutrition Registered Dietitian is a narrow specialty nationwide, with 1,446 enrolled providers across 52 states and an average of 68 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.
