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).

Silvia Marroquin Castillo, PA appears in the CMS NPPES registry as a Physician Assistant provider holding PA credentials at 1321 NW 14TH ST, Miami, FL, 33125, with a listed phone of (305) 324-0220. NPI 1497106934 was issued on 06/27/2016.

Medicare Part D records for calendar year 2023 show 243 prescription claims written by this provider, covering 180 Medicare beneficiaries and totaling roughly $3K in drug spend. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 46.3/100 for the 2023 performance year (Quality 51, Cost 60.8), compared with the 83.5 average among clinicians with a measured score.

Physician Assistant is a high-volume specialty nationwide, with 150,974 enrolled providers across 56 states and an average of 790 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.
