S02.6Fracture of mandible

S02.6 is the ICD-10-CM diagnosis code for fracture of mandible. 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 (fracture of skull and facial bones), S02.6 is specifically for fracture of mandible. Related codes cover fracture of vault of skull (S02.0), fracture of base of skull (S02.1), fracture of nasal bones (S02.2), fracture of orbital floor (S02.3), fracture of malar, maxillary and zygoma bones (S02.4), fracture of tooth (traumatic) (S02.5), fractures of other specified skull and facial bones (S02.8) and fracture of unspecified skull and facial bones (S02.9).

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.
