Additional Info

NOS in this case means that it is not clear if the condition is acute or chronic.

AKA ischemic bowel, ischemic gut

This refers to ischemia of small or large intestine.

• AG RESPONSE: There are 3 ICD10 codes that cover ischemia of the intestinal tract (any part):
  • Ischemic colitis, acute
  • Ischemic colitis, chronic
  • Ischemic colitis (mesenteric arterial disease), NOS

• • So, we are going to rename these to be: Mesenteric ischemia -- acute or chronic or NOS (includes small and large bowel)

• For ischemia of stomach or esophagus, stomach or liver, you're right there's no specific codes so supposed to use:
  • Disorder of esophagus, NOS
• Disorder of stomach or duodenum, NOS
• Disorder of liver, NOS

Alternate ICD10s to consider coding instead or in addition

• Ischemic colitis, acute
• Ischemic colitis, chronic
• Duodenitis
• Ulcerative colitis
• Gastrointestinal infection (gastroenteritis), bacterial, NOS
• Gastrointestinal infection (gastroenteritis), viral
• Gastrointestinal infection (gastroenteritis), protozoal, NOS
• Gastrointestinal infection (gastroenteritis, colitis), bug NOS
• Colitis, enteritis, entercolitis, or gastroenteritis, noninfectious NOS
