Traumatic aortic injury dx coding- excludes notes

Hello all,

I have a patient that is diagnosed with a traumatic aortic dissection and an aortic pseudo-aneurysm. The dissection injury code (901.0) has an excludes note regarding the aneurysm code - is this a mutually exclusive "excludes" note or is telling me to also code the aneurysm?

I can't wait for ICD-10 to come out so the "excludes" rules will be clearer.

Thanks!
