Excludes2 inherited from the categories above S02.842

Also inherited, and the opposite of Excludes1: these conditions are not part of S02.842, but a patient can have both, so you may code both.

Other codes that can never be billed with S02.842

These codes carry an Excludes1 note pointing at S02.842. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S02.842 alone.

Risk adjustment

S02.842 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.

S02.842 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
