About Q63

Q63 is the ICD-10-CM diagnosis code for other congenital malformations of kidney. It belongs to block Q60-Q64 (congenital malformations of the urinary 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q63.0 (kidney), Q63.1 (kidney), Q63.2 (kidney), Q63.3 (kidney), Q63.8 (kidney) and Q63.9 (unspecified).

Don't report Q63 together with the conditions in its Excludes1 note: congenital nephrotic syndrome (N04.-).

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