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).

GLORIA ARROYO-BOSCH is a Radiation Oncology Physician provider practicing in BAYAMON, Puerto Rico, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1477685832.

GLORIA ARROYO-BOSCH appears in the CMS NPPES registry as a Radiation Oncology Physician provider at EXT. HNAS. DAVILA MARGINAL PR 2, BAYAMON, PR, 00959, with a listed phone of (787) 966-7500. NPI 1477685832 was issued on 03/12/2007.

Medicare Part D records for calendar year 2023 show 84 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $3K in drug spend, split 21% brand-name and 79% generic by claim count.

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.
