Excludes1 inherited from the categories above S80.871D

These are not written on S80.871D, but they bind it: a note on a category applies to every code beneath it. Billing S80.871D with anything listed here is a denial.

Written on S80.87 Other superficial bite of lower leg

  • open bite of lower leg (S81.85-)

Excludes2 inherited from the categories above S80.871D

Also inherited, and the opposite of Excludes1: these conditions are not part of S80.871D, but a patient can have both, so you may code both.

Written on S80 Superficial injury of knee and lower leg

  • superficial injury of ankle and foot (S90.-)

Risk adjustment

S80.871D 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

S80.871D 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.
