Excludes2 inherited from the categories above Z96.65
Also inherited, and the opposite of Excludes1: these conditions are not part of Z96.65, but a patient can have both, so you may code both.
Other codes that can never be billed with Z96.65
These codes carry an Excludes1 note pointing at Z96.65. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z96.65 alone.

Risk adjustment
Z96.65 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
