Vascular disorders of intestine (K55)

Browse all the diagnosis codes used for vascular disorders of intestine (k55). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Superior Mesenteric Artery Syndrome - DUODENAL OBSTRUCTION by the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) which travels in the root of the MESENTERY and crosses over the DUODENUM. The syndrome is characterized by the dilated proximal duodenum and STOMACH, bloating, ABDOMINAL CRAMPS, and VOMITING. Often it is observed in patient with body casts after spinal surgery.

Instructional Notations

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • necrotizing enterocolitis of newborn P77

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
