Hypersplenism

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A condition where the spleen becomes overactive and destroys blood cells too quickly, leading to low blood cell counts.

Coding Tips

•Hypersplenism is often secondary to other conditions; investigate and code the underlying cause if documented
•Verify whether this is primary hypersplenism or secondary to conditions like cirrhosis, portal hypertension, or lymphoma
