Z98.8 — Other specified postprocedural states
Z98.8 is a non-billable header ICD-10-CM code for other specified postprocedural states. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above Z98.8
Also inherited, and the opposite of Excludes1: these conditions are not part of Z98.8, but a patient can have both, so you may code both.
Other codes that can never be billed with Z98.8
These codes carry an Excludes1 note pointing at Z98.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z98.8 alone.
Risk adjustment
Z98.8 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.
Code history
Z98.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
