Q79.5Other congenital malformations of abdominal wall

Q79.5 is the ICD-10-CM diagnosis code for other congenital malformations of abdominal wall. It belongs to category Q79 (congenital malformations of musculoskeletal system, not elsewhere classified), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within Q79, choose Q79.5 (Other congenital malformations of abdominal wall) only when documentation doesn't support a more specific option: congenital diaphragmatic hernia (Q79.0), other congenital malformations of diaphragm (Q79.1), Exomphalos (Q79.2), gastroschisis (Q79.3), prune belly syndrome (Q79.4), Ehlers-Danlos syndromes (Q79.6), other congenital malformations of musculoskeletal system (Q79.8) and congenital malformation of musculoskeletal system, unspecified (Q79.9).

To report this condition, pick the subcode that matches the documentation: Q79.51 (bladder) and Q79.59 (wall).

Don't report Q79.5 together with the conditions in its Excludes1 note: umbilical hernia (K42.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
