Article Overview

This article explains general critical care coding guidance for multiple patient populations and care settings. It is intended for coders, CDI staff, and billing professionals who need a high-level understanding of how critical care services are categorized, how pediatric and neonatal situations differ from adult reporting, and how postoperative modifier concepts affect reporting. The article emphasizes framework-level guidance rather than clinical detail.
