About coding vertebral artery aneurysm
The ICD-10-CM code for vertebral artery aneurysm is I72.6 (Aneurysm of vertebral artery).
Within I72 (other aneurysm), I72.6 is specifically for aneurysm of vertebral artery. Related codes cover carotid artery (I72.0), artery of upper extremity (I72.1), renal artery (I72.2), iliac artery (I72.3), artery of lower extremity (I72.4), other precerebral arteries (I72.5), other specified arteries (I72.8) and unspecified site (I72.9).
The conditions in its Excludes2 note aren't part of I72.6, but may be coded alongside it if the patient has both: dissection of vertebral artery (I77.74).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
