About S02.40

S02.40 is the ICD-10-CM diagnosis code for fracture of malar, maxillary and zygoma bones, unspecified. It belongs to category S02 (fracture of skull and facial bones), block S00-S09 (injuries to the head) 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 9 subcodes must be used instead.

Within S02.4, choose S02.40 (unspecified) only when documentation doesn't support a more specific option: LeFort fracture (S02.41) and fracture of alveolus of maxilla (S02.42).

Codes in this range require a 7th character: A for initial encounter for closed fracture, B for initial encounter for open fracture, D for subsequent encounter for fracture with routine healing, G for subsequent encounter for fracture with delayed healing, K for subsequent encounter for fracture with nonunion 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.
