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).

MEREDITH BERGER, MD appears in the CMS NPPES registry as a Endocrinology, Diabetes & Metabolism Physician provider holding MD credentials at 348 BROWN'S HILL CT, MIDLOTHIAN, VA, 23114, with a listed phone of (804) 272-2702. NPI 1831181734 was issued on 08/17/2005.

Medicare Part D records for calendar year 2023 show 5,846 prescription claims written by this provider, covering 665 Medicare beneficiaries and totaling roughly $1.3 million in drug spend, split 40% brand-name and 60% generic by claim count.

Endocrinology, Diabetes & Metabolism Physician is a mid-sized specialty nationwide, with 7,852 enrolled providers across 54 states and an average of 2,639 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.
