Excludes1 inherited from the categories above S00.10XA

These are not written on S00.10XA, but they bind it: a note on a category applies to every code beneath it. Billing S00.10XA with anything listed here is a denial.

Written on S00 Superficial injury of head

  • diffuse cerebral contusion (S06.2-)
  • focal cerebral contusion (S06.3-)
  • injury of eye and orbit (S05.-)
  • open wound of head (S01.-)

Excludes2 inherited from the categories above S00.10XA

Also inherited, and the opposite of Excludes1: these conditions are not part of S00.10XA, but a patient can have both, so you may code both.

Written on S00.1 Contusion of eyelid and periocular area

  • contusion of eyeball and orbital tissues (S05.1-)

Risk adjustment

S00.10XA 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

S00.10XA 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.
