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).

CHRISTINA MAMALIS, MD is a Cornea and External Diseases Specialist Physician provider practicing in MAYWOOD, Illinois, according to the CMS National Plan and Provider Enumeration System (NPPES).

CHRISTINA MAMALIS, MD appears in the CMS NPPES registry as a Cornea and External Diseases Specialist Physician provider holding MD credentials at 2160 S 1ST AVE, MAYWOOD, IL, 60153, with a listed phone of (708) 216-9000. NPI 1063876530 was issued on 04/11/2016.

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.
