S72.1Pertrochanteric fracture

S72.1 is the ICD-10-CM diagnosis code for Pertrochanteric fracture. It belongs to category S72 (fracture of femur), 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 5 subcodes must be used instead.

Within S72 (fracture of femur), S72.1 is specifically for Pertrochanteric fracture. Related codes cover fracture of head and neck of femur (S72.0), subtrochanteric fracture of femur (S72.2), fracture of shaft of femur (S72.3), fracture of lower end of femur (S72.4), other fracture of femur (S72.8) and unspecified fracture of femur (S72.9).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture type I or II, C for initial encounter for open fracture type IIIA, IIIB, or IIIC, D for subsequent encounter for closed fracture with routine healing, E for subsequent encounter for open fracture type I or II with routine healing, F for subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing and 10 more. 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.
