Monocytosis (symptomatic)

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

What This Code Means

An abnormally high number of monocytes (a type of white blood cell) in the blood that is causing symptoms. Monocytes help fight infections and clear dead cells, and elevated levels may indicate infection or inflammation.

Coding Tips

  • •Ensure documentation specifically mentions monocytosis with symptoms to justify this code
  • •Investigate whether this is a reactive process (infection, inflammation) or part of a hematologic disorder

Excludes 1 — Do NOT code together

  • infectious mononucleosis (B27.-)
