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).

RUBIROSA ARANDIA is a Family Nurse Practitioner provider practicing in MERCED, California, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1003401035. 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.

RUBIROSA ARANDIA appears in the CMS NPPES registry as a Family Nurse Practitioner provider at 3389 G ST, MERCED, CA, 95340, with a listed phone of (209) 384-9401. NPI 1003401035 was issued on 03/02/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ARANDIA 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 547 prescription claims written by this provider, covering 133 Medicare beneficiaries and totaling roughly $147K in drug spend, split 32% brand-name and 68% 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.

Family Nurse Practitioner is a high-volume specialty nationwide, with 209,817 enrolled providers across 56 states and an average of 1,222 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.
