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 KLINE, MD is a Specialist provider practicing in HIAWATHA, Iowa, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1003896176.

MARK KLINE, MD appears in the CMS NPPES registry as a Specialist provider holding MD credentials at 1550 BOYSON RD, HIAWATHA, IA, 52233, with a listed phone of (319) 743-7300. NPI 1003896176 was issued on 01/17/2006.

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.
