About I72
I72 is the ICD-10-CM diagnosis code for other aneurysm. It belongs to block I70-I79 (diseases of arteries, arterioles and capillaries) and chapter 9 (diseases of the circulatory system). 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: I72.0 (artery), I72.1 (extremity), I72.2 (artery), I72.3 (artery), I72.4 (extremity), I72.5 (arteries), I72.6 (artery), I72.8 (arteries) and 1 more.
The conditions in its Excludes2 note aren't part of I72, but may be coded alongside it if the patient has both: acquired aneurysm (I77.0), aneurysm (of) aorta (I71.-), aneurysm (of) arteriovenous NOS (Q27.3-), carotid artery dissection (I77.71) and 14 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
