About S02

S02 is the ICD-10-CM diagnosis code for fracture of skull and facial bones. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: S02.0 (skull), S02.1 (skull), S02.2 (bones), S02.3 (floor), S02.4 (bones), S02.5 ((traumatic)), S02.6 (mandible), S02.8 (bones) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
