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).

REGINALDO HORWITZ, DNP, AGPCNP, AGCNS appears in the CMS NPPES registry as a Critical Care Medicine Clinical Nurse Specialist provider holding DNP, AGPCNP, AGCNS credentials at 508 FULTON ST, DURHAM, NC, 27705, with a listed phone of (919) 286-0411. NPI 1295373967 was issued on 12/12/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HORWITZ 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Critical Care Medicine Clinical Nurse Specialist providers operate outside Part D entirely.

Critical Care Medicine Clinical Nurse Specialist is a narrow specialty nationwide, with 211 enrolled providers across 34 states and an average of 963 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.
