Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- An amputation not identified as partial or complete should be coded to complete
Other codes that can never be billed with S98
These codes carry an Excludes1 note pointing at S98. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S98 alone.
Risk adjustment
S98 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 S98
5 child codes. Green means billable.
