Billable

Irritable bowel syndrome with constipation

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

What This Code Means

Irritable bowel syndrome characterized primarily by constipation, a condition where the colon is overly sensitive and causes abdominal pain, bloating, and difficulty with bowel movements.

Coding Tips

  • •Verify documentation specifies constipation-predominant IBS; if symptoms are mixed, consider K58.2 instead
  • •IBS is a functional disorder diagnosis; ensure organic causes have been ruled out before coding
