Anal abscess

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

What This Code Means

A collection of pus or infected fluid in the tissue around the anus.

Coding Tips

  • •Distinguish from anorectal fistula (K60 codes) as an abscess is an acute collection of pus, not a chronic tract
  • •Document location (intersphincteric, ischiorectal, submucosal, or supralevator) if available for more specific coding if needed

Excludes 2 — Not included here, may code separately

  • intrasphincteric abscess (K61.4)
