Periumbilic abdominal rigidity

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

What This Code Means

Stiffness or hardness of the abdominal muscles around the belly button area, which may indicate inflammation of abdominal organs in that region.

Coding Tips

  • •Document the severity and duration of the rigidity along with any precipitating factors
  • •Distinguish from epigastric rigidity (R19.36) by confirming the finding is centered around the umbilicus
