About S88

S88 is the ICD-10-CM diagnosis code for traumatic amputation of lower leg. It belongs to block S80-S89 (injuries to the knee and lower leg) 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 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S88.0 (level), S88.1 (ankle) and S88.9 (level unspecified).

Don't report S88 together with the conditions in its Excludes1 note: traumatic amputation of ankle and foot (S98.-).

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