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 Pediatric Registered Nurse. 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).
Dorothy Worika appears in the CMS NPPES registry as a Pediatric Registered Nurse provider at 65 E UNIVERSITY DR, Tempe, AZ, 85281, with a listed phone of (623) 624-8280. NPI 1164740932 was issued on 05/04/2010.
Medicare Part D records for calendar year 2023 show 873 prescription claims written by this provider, covering 141 Medicare beneficiaries and totaling roughly $62K in drug spend, with an opioid prescribing rate of 4.8%.
Pediatric Registered Nurse is a narrow specialty nationwide, with 2,908 enrolled providers across 52 states and an average of 748 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.

Before you book an appointment
Use this federal record as your verification checklist, not as a recommendation.
- Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
- Check the active license and any disciplinary history with the Arizona medical board, federal registration is not a license check. Credential verification guide
- Weigh a second option: compare this provider with a nearby Pediatric Registered Nurse peer on Medicare volume and prescribing patterns. Compare providers
