About S71.1

S71.1 is the ICD-10-CM diagnosis code for open wound of thigh. It belongs to category S71 (open wound 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 6 subcodes must be used instead.

Within S71 (open wound of hip and thigh), S71.1 is specifically for open wound of thigh. Related codes cover hip (S71.0).

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.
