K50.913 and K50.114

Chrohns flare is a chronic transmural inflammation that may involve any part of the digestive tract from mouth to anus, mostly found in the ileum, the cecum, and the colon. In crohn disease, the inflammation, extending through the intestinal wall from the mucosa to the serosa, is characteristically asymmetric and segmental. Epithelioid granulomas may be seen in some patients.

Fistula is a condition in which there is an abnormal passage from one organ to another or from a hollow organ to the surface.

If we first lead index in ICD 10

Crohn's disease - see Enteritis, regional

Also if we see ICD 10 for rectum it is leading to code from enteritis regional large intestine.

regional (of) K50.90
complication K50.919
abscess K50.914
fistula K50.913
intestinal obstruction K50.912
rectal bleeding K50.911
specified complication NEC K50.918
colon - see Enteritis, regional, large intestine
duodenum - see Enteritis, regional, small intestine
ileum - see Enteritis, regional, small intestine
jejunum - see Enteritis, regional, small intestine
large bowel - see Enteritis, regional, large intestine
large intestine (colon) (rectum) K50.10
complication K50.119
abscess K50.114
fistula K50.113
intestinal obstruction K50.112
rectal bleeding K50.111
small intestine (duodenum) (ileum) (jejunum) K50.80
complication K50.819
abscess K50.814
fistula K50.813
intestinal obstruction K50.812
rectal bleeding K50.811
specified complication NEC K50.818
specified complication NEC K50.118

rectum - see Enteritis, regional, large intestine

So if we go for abscess in the rectal region or perirectal region we have to code from large intestine as per ICD 10. It leads to code K50.114.

As per the document the site is not specified for fistula . so we can go for the code K50.913

I am thinking we can use both the codes to satisfy the criteria.

K50.913 and K50.114

As there are no chapter specific guidelines to state that we have to use only one code for hernia, as long as the document fulfills to record ICD 10 code we can use both the codes.

If my understanding is wrong please correct.

Thank you.

Yes you can use more than one Crohns dx code. There are no excludes 1 notes or guidelines that say otherwise. Its similar to diabetes, you give more than one diabetes code if you have more than one complication.
