About S98

S98 is the ICD-10-CM diagnosis code for traumatic amputation of ankle and foot. It belongs to block S90-S99 (injuries to the ankle and foot) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S98.0 (level), S98.1 (toe), S98.2 (toes), S98.3 (midfoot) and S98.9 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
