Questions About K52Overview

What is the ICD-10 code for other and unspecified noninfective gastroenteritis and colitis?

K52 is the ICD-10-CM category for other and unspecified noninfective gastroenteritis and colitis, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is K52 a billable code?

No. This is a category header that groups the codes for other and unspecified noninfective gastroenteritis and colitis, and headers cannot be submitted on claims. Claims for other and unspecified noninfective gastroenteritis and colitis need a more specific code from this category, such as K52.0, K52.1, and K52.21.

Can K52 be reported with a code from K58?

Not as a rule. The Excludes1 note at block K50-K52, which applies to K52, lists "irritable bowel syndrome (K58.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
