MIPS final score (Oncology Registered Nurse) — 73.5637/100 vs national avg 83.1

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).

EMILY KOPAS is a Oncology Registered Nurse provider practicing in GREENWICH, Connecticut, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1427667435.

NPI 1427667435 was issued on 07/26/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KOPAS 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 records for calendar year 2023 show 90 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $543K in drug spend, split 54% brand-name and 46% generic by claim count.

Oncology Registered Nurse is a narrow specialty nationwide, with 857 enrolled providers across 50 states and an average of 555 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.
