About Q22

Q22 is the ICD-10-CM diagnosis code for congenital malformations of pulmonary and tricuspid valves. It belongs to block Q20-Q28 (congenital malformations of the circulatory 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q22.0 (atresia), Q22.1 (stenosis), Q22.2 (insufficiency), Q22.3 (valve), Q22.4 (stenosis), Q22.5 (anomaly), Q22.6 (syndrome), Q22.8 (valve) and 1 more.

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