K58 is a non-billable header ICD-10-CM code for irritable bowel syndrome. It cannot be billed on its own: choose one of the more specific child codes below.

Includes

Conditions this code covers.

  • irritable colon
  • spastic colon

Other codes that can never be billed with K58

These codes carry an Excludes1 note pointing at K58. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K58 alone.

Risk adjustment

K58 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead K58

5 child codes. Green means billable.
