Article Overview
This article addresses a coding question about the role of causative organism reporting in infectious disease cases. It is aimed at coders, CDI specialists, and revenue integrity professionals who work with ICD-10-CM diagnosis coding, CC/MCC assignment, and APR-DRG severity of illness/risk of mortality concepts. The discussion gives a high-level clarification of when organism identification may matter, including the use of categories B95-B97 and the broader concept of combination codes versus separate diagnosis reporting.
Why This Topic Matters
Understanding how organism identification can affect diagnosis grouping and severity measures helps coding and CDI teams support more complete documentation review and more consistent diagnosis assignment.
