S79.9Unspecified injury of hip and thigh

S79.9 is the ICD-10-CM diagnosis code for unspecified injury of hip and thigh. It belongs to category S79 (other and unspecified injuries of hip and thigh), 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 2 subcodes must be used instead.

Within S79, choose S79.9 (Unspecified injury of hip and thigh) only when documentation doesn't support a more specific option: physeal fracture of upper end of femur (S79.0), physeal fracture of lower end of femur (S79.1) and other specified injuries of hip and thigh (S79.8).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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