Specialty board-certified rate — General Practice Physician estimate
Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus Maintenance of Certification cycles. CMS does not publish a per-provider board-certification field; the figure shown is the specialty-level estimated rate from ABMS / AOA reference data.
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).
RAFAEL JUSTINIANO MAGRANER, M.D. appears in the CMS NPPES registry as a General Practice Physician provider holding M.D. credentials at 1541 KINGS HWY, SHREVEPORT, LA, 71103, with a listed phone of (318) 626-0000. NPI 1871925297 was issued on 08/08/2013.

Medicare Part D records for calendar year 2023 show 2,104 prescription claims written by this provider, covering 388 Medicare beneficiaries and totaling roughly $416K in drug spend, with an opioid prescribing rate of 1.0%.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 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.
