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).

HILARY ALLEN is a Obstetrics & Gynecology Physician provider practicing in RENO, Nevada, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1629465463.

HILARY ALLEN appears in the CMS NPPES registry as a Obstetrics & Gynecology Physician provider at 635 INNOVATION DR STE 300, RENO, NV, 89511, with a listed phone of (775) 329-6241. NPI 1629465463 was issued on 04/20/2015.

Medicare Part D records for calendar year 2023 show 62 prescription claims written by this provider, covering 12 Medicare beneficiaries and totaling roughly $5K 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.

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.
