About S77.1

S77.1 is the ICD-10-CM diagnosis code for crushing injury of thigh. It belongs to category S77 (crushing injury 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).

Within S77 (crushing injury of hip and thigh), S77.1 is specifically for crushing injury of thigh. Related codes cover hip (S77.0) and hip with thigh (S77.2).
