Excludes1 inherited from the categories above S09.319D
These are not written on S09.319D, but they bind it: a note on a category applies to every code beneath it. Billing S09.319D with anything listed here is a denial.
Excludes2 inherited from the categories above S09.319D
Also inherited, and the opposite of Excludes1: these conditions are not part of S09.319D, but a patient can have both, so you may code both.
Risk adjustment
S09.319D 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
S09.319D has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
