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).

JUAN MARRERO GRATACOS appears in the CMS NPPES registry as a General Practice Dentistry provider at 1326 STE 107, PONCE, PR, 00717, with a listed phone of (787) 812-1010. NPI 1831224294 was issued on 02/23/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARRERO GRATACOS 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 892 prescription claims written by this provider, covering 402 Medicare beneficiaries and totaling roughly $7K in drug spend. 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.

General Practice Dentistry is a high-volume specialty nationwide, with 121,627 enrolled providers across 56 states and an average of 82 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.
