S93 — Dislocation and sprain of joints and ligaments at ankle, foot and toe level
S93 is a non-billable header ICD-10-CM code for dislocation and sprain of joints and ligaments at ankle, foot and toe level. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

S93 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 to one of these instead S93
6 child codes. Green means billable.
