ICD-10 code for cheek external wound

The ICD-10-CM code for cheek external wound is S01.40 (Unspecified open wound of cheek and temporomandibular area).

Within S01.4, choose S01.40 (Unspecified open wound of cheek and temporomandibular area) only when documentation doesn't support a more specific option: laceration without foreign body of cheek and temporomandibular area (S01.41), laceration with foreign body of cheek and temporomandibular area (S01.42), puncture wound without foreign body of cheek and temporomandibular area (S01.43), puncture wound with foreign body of cheek and temporomandibular area (S01.44) and open bite of cheek and temporomandibular area (S01.45).

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.
