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).

THOMAS WARREN, MD appears in the CMS NPPES registry as a Otolaryngology/Facial Plastic Surgery Physician provider holding MD credentials at 140 GATEWAY BLVD, MOORESVILLE, NC, 28117, with a listed phone of (704) 664-9638. NPI 1386715639 was issued on 11/10/2006.

Medicare Part D records for calendar year 2023 show 906 prescription claims written by this provider, covering 307 Medicare beneficiaries and totaling roughly $30K in drug spend, with an opioid prescribing rate of 2.0%. 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.

Otolaryngology/Facial Plastic Surgery Physician is a narrow specialty nationwide, with 744 enrolled providers across 53 states and an average of 561 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.
