Hemolytic-Uremic Syndrome

Code D59.3, Hemolytic-uremic syndrome, was expanded and new codes created to identify hemolytic-uremic syndrome, unspecified (D59.30), infection-associated hemolytic-uremic syndrome (D59.31), hereditary hemolytic-uremic syndrome (D59.32), and other hemolytic-uremic syndrome (D59.39).Hemolytic-uremic syndrome (HUS) is a rare but serious disease that affects the kidneys and blood clotting mechanisms of affected people. Typical HUS is the most common form, and occurs secondary to shiga toxin (Stx) producing bacteria, typically following an Escherichia coli 0157:H7 gastrointestinal (GI) infection. Anyone who has been infected with an E. coli O157:H7 strain can develop HUS; however, only a small percentage will...

Article Overview

This article reviews an ICD-10-CM update involving hemolytic-uremic syndrome and outlines the major ways the condition is grouped for coding purposes. It is relevant to coders, CDI staff, and clinical documentation teams who work with hematology, nephrology, pediatrics, and infection-related diagnoses. The article also discusses broad clinical context, including typical and atypical presentations and associated conditions that may appear in documentation.

Why This Topic Matters

Hemolytic-uremic syndrome can be documented in several different ways, and the article helps readers understand the scope of the coding update and the clinical contexts that may affect record review. It is useful for identifying when documentation may reference infection-related, hereditary, or other forms of the syndrome, as well as when additional chronic condition coding may be present.

Article Sections

  1. ICD-10-CM update for hemolytic-uremic syndrome

    Introduces the coding update for hemolytic-uremic syndrome and the broader grouping changes discussed in the article.

  2. Clinical background and common associations

    Summarizes the condition, common clinical context, and general associations that may appear in documentation.

  3. Atypical hemolytic-uremic syndrome and related context

    Discusses atypical forms of the syndrome, including broad categories of underlying causes and possible triggering events.

  4. Example query and related coding context

    Presents a documentation scenario involving hemolytic-uremic syndrome alongside other chronic diagnoses and references the related coding context.
