Other codes that can never be billed with W46.0XXS
These codes carry an Excludes1 note pointing at W46.0XXS. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W46.0XXS alone.
Risk adjustment
W46.0XXS 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.

W46.0XXS has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
