About S79

S79 is the ICD-10-CM diagnosis code for other and unspecified injuries 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S79.0 (femur), S79.1 (femur), S79.8 (thigh) and S79.9 (thigh).

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