About S02.31

S02.31 is the ICD-10-CM diagnosis code for fracture of orbital floor, right side. 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 6 subcodes must be used instead.

Within S02.3 (fracture of orbital floor), S02.31 is specifically for fracture of orbital floor, right side. Related codes cover unspecified side (S02.30) and left side (S02.32).

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 was added in FY2017, effective October 1, 2016.
