Other congenital malformations of digestive system (Q45)

Browse all the diagnosis codes used for other congenital malformations of digestive system (q45). 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.

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

Mesenteric Cyst - A rare intra-abdominal tumor in the MESENTERY. Mesenteric cysts are usually benign and can be very large fluid-filled (2000 mL) lesions.

Pancreas Divisum - Anatomic variants in PANCREATIC DUCTS characterized by failure of fusion of the ventral and dorsal endodermal buds. Pancreas divisum results in inadequate or no communication between dorsal and ventral ducts. While most cases are asymptomatic, it may be associated with recurrent PANCREATITIS.

Instructional Notations

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.
