About coding sinus fracture

The ICD-10-CM code for sinus fracture is S02.19 (Other fracture of base of skull).

Within S02.1, choose S02.19 (Other fracture of base of skull) only when documentation doesn't support a more specific option: unspecified fracture of base of skull (S02.10), fracture of occiput (S02.11) and fracture of orbital roof (S02.12).

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.
