Other codes that can never be billed with Q87.41
These codes carry an Excludes1 note pointing at Q87.41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q87.41 alone.
Risk adjustment
Q87.41 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.

Q87.41 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
