K50.81Crohn's disease of both small and large intestine with complications

K50.81 is the ICD-10-CM diagnosis code for Crohn's disease of both small and large intestine with complications. It belongs to category K50 (Crohn's disease [regional enteritis]), block K50-K52 (noninfective enteritis and colitis) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

Within K50.8 (Crohn's disease of both small and large intestine), K50.81 is specifically for Crohn's disease of both small and large intestine with complications. Related codes cover without complications (K50.80).

To report this condition, pick the subcode that matches the documentation: K50.811 (bleeding), K50.812 (obstruction), K50.813 (fistula), K50.814 (abscess), K50.818 (complication) and K50.819 (complications).

Use an additional code to identify any associated fistulas, if applicable: anal fistula (K60.3-), anorectal fistula (K60.5-) and rectal fistula (K60.4-). Use an additional code to identify manifestations, such as: pyoderma gangrenosum (L88).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
