Template:ICD10 Guideline Regional Ischemia

• 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 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:
  • Atherosclerosis of the relevant regional arterial tree -- e.g. Atherosclerosis of arteries of arms or legs
  • Thromboembolism 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.
