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).

MARK BAILEY is a Family Nurse Practitioner provider practicing in LEBANON, Tennessee, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1891226817.

MARK BAILEY appears in the CMS NPPES registry as a Family Nurse Practitioner provider at 217 E HIGH ST STE 200, LEBANON, TN, 37087, with a listed phone of (615) 227-3000. NPI 1891226817 was issued on 03/22/2017.

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.
