About S74.00

S74.00 is the ICD-10-CM diagnosis code for injury of sciatic nerve at hip and thigh level, unspecified leg. It belongs to category S74 (injury of nerves at hip and thigh level), 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 3 subcodes must be used instead.

Within S74.0, choose S74.00 (unspecified leg) only when documentation doesn't support a more specific option: right leg (S74.01) and left leg (S74.02).

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.
