Additional Info

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

Ischemic gut guideline

• SMW

• Cargo

• Categories

There are separate codes for different parts of the ischemic gut:

• The following 3 items refer to ischemia of the intestines, including small bowel (including duodenem), or colon, rectum, anus
  • Mesenteric ischemia, acute
  • Mesenteric ischemia, chronic
  • Mesenteric ischemia, NOS
• For ischemia of the stomach -- use Disorder of stomach or duodenum, NOS
• For ischemia of the liver -- use Disorder of liver, NOS
• For ischemia of the esophagus --- use Disorder of esophagus, NOS
• Thus, these various codes variously cover the following concepts:
  • "ischemic bowel"
  • "ischemic gut"
  • "mesenteric arterial thrombosis, embolism or thromboembolism"
  • "mesenteric vein thrombosis, embolism or thromboembolism"
  • "mesenteric arterial atherosclerosis"
• But these codes do NOT include:
  • The cause of that ischemia/infarction. As usual, if the cause is known, link the code for the cause to the relevant code as above for the ischemia, e.g: Atherosclerosis of arteries, NOS, Thrombosis or embolism of artery, NOS, Septic Thrombosis or Embolism, NOS, Disorder of artery/arteries, NOS
  • GI arterial disorders in the absence of mesenteric ischemia/infarction.

• Ischemia is an entity that can be contributed to my a variety of causes, and in any organ or body region
• When regional ischemia is present, you should use the ICD10 Category:Ischemia code for that body region, e.g. Limb ischemia (upper or lower), Mesenteric ischemia, acute
• IF known, you should also link to the ischemia code the contributing cause or causes, which may include:
  • the Category:Atherosclerosis code of the relevant regional arterial tree -- e.g. Atherosclerosis of arteries of arms or legs
  • the Category:Venous thromboembolism / Category:Arterial thromboembolism code of the relevant regional arterial tree -- e.g. Thromboembolism/embolism, renal vein
  • Compartment Syndrome
  • Mechanical compression of a limb or its vessels (as most often occurs in trauma situations)
  • Use of vasoconstrictor medications, for whatever indication
• Of course, a patient may have any of these potential causes of ischemia without ischemia.

Alternate ICD10s to consider coding instead or in addition

• Duodenitis
• Ulcerative colitis
