About S78

S78 is the ICD-10-CM diagnosis code for traumatic amputation of hip and thigh. It belongs to block S70-S79 (injuries to the hip and thigh) 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: S78.0 (joint), S78.1 (knee) and S78.9 (level unspecified).

Don't report S78 together with the conditions in its Excludes1 note: traumatic amputation of knee (S88.0-).

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