Excludes1 inherited from the categories above S02.30XK

These are not written on S02.30XK, but they bind it: a note on a category applies to every code beneath it. Billing S02.30XK with anything listed here is a denial.

Written on S02.3 Fracture of orbital floor

Excludes2 inherited from the categories above S02.30XK

Also inherited, and the opposite of Excludes1: these conditions are not part of S02.30XK, but a patient can have both, so you may code both.

Written on S02.3 Fracture of orbital floor

Other codes that can never be billed with S02.30XK

These codes carry an Excludes1 note pointing at S02.30XK. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S02.30XK alone.

  • S01Open wound of head

Risk adjustment

S02.30XK 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.

Medicare coverage

S02.30XK is named in 2 Medicare coverage policies 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
