Excludes1 inherited from the categories above S89.132A

These are not written on S89.132A, but they bind it: a note on a category applies to every code beneath it. Billing S89.132A with anything listed here is a denial.

Written on S89.13 Salter-Harris Type III physeal fracture of lower end of tibia

  • fracture of medial malleolus (adult) (S82.5-)

Excludes2 inherited from the categories above S89.132A

Also inherited, and the opposite of Excludes1: these conditions are not part of S89.132A, but a patient can have both, so you may code both.

Written on S89 Other and unspecified injuries of lower leg

  • other and unspecified injuries of ankle and foot (S99.-)

Risk adjustment

S89.132A 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

S89.132A is named in 3 Medicare coverage policies 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
