Other congenital malformations of digestive system (Q45) ICD-10-CM
The Q45 code range covers other congenital malformations of digestive system with 7 ICD-10-CM diagnosis codes. 6 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.

About the Q45 Code Range
These are digestive system malformations present at birth, with most of the listed subdivisions focused on the pancreas.
The pancreas codes separate an absent or underdeveloped pancreas (Q45.0), a ring-shaped pancreas (Q45.1), pancreatic cysts (Q45.2), and other malformations of the pancreas or its duct (Q45.3). The remaining subdivisions identify other specified digestive system malformations (Q45.8) or an unspecified digestive system malformation (Q45.9).
