Excludes1 inherited from the categories above Y36.530D
These are not written on Y36.530D, but they bind it: a note on a category applies to every code beneath it. Billing Y36.530D with anything listed here is a denial.
Other codes that can never be billed with Y36.530D
These codes carry an Excludes1 note pointing at Y36.530D. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Y36.530D alone.
Risk adjustment
Y36.530D 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.

Y36.530D has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
