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).

NANCY BROCK, O.D. is a Pediatric Optometrist provider practicing in HAPPY VALLEY, Oregon, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: O.D.. NPI: 1447306360. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

NANCY BROCK, O.D. appears in the CMS NPPES registry as a Pediatric Optometrist provider holding O.D. credentials at 13180 SE 169TH AVE STE 104, HAPPY VALLEY, OR, 97086, with a listed phone of (503) 698-2375. NPI 1447306360 was issued on 01/25/2007.

Medicare Part D records for calendar year 2023 show 55 prescription claims written by this provider, covering 20 Medicare beneficiaries and totaling roughly $4K in drug spend, split 38% brand-name and 62% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Pediatric Optometrist is a narrow specialty nationwide, with 316 enrolled providers across 43 states and an average of 184 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.
