Eye Injuries and Complications

Injuries to the eye are coded in chapter 19. Unlike the ICD-9 code book, the injury chapter in ICD-10 is not organized by type of injury. Rather, it is organized anatomically, and then by type of injury.

For example, a laceration without foreign body of the left eyelid and periocular area is code with diagnosis code S01.112. Injury codes in ICD-10 require a seventh character to indicate the number of the encounter that the patient is being seen for that injury (eg, initial encounter vs subsequent or follow-up encounter). The first patient encounter for the injury would be coded as S01.112A. A follow-up encounter uses the same code but changes the seventh character extender, so the code for a subsequent encounter would be S01.112D.

ICD-10 includes intraoperative and postprocedural complications in the chapter-related system, another change from ICD-9. In the eye chapter, these complications are in the H59 block, which has 57 diagnosis codes for disorders of the eye following cataract surgery, intraoperative hemorrhage and hematoma of the eye and adnexa, accidental puncture and laceration of the eye and adnexa, postprocedural hemorrhage, inflammation (infection) of postprocedural bleb, chorioretinal scars after surgery for detachment, and other intraoperative or postoperative complications not elsewhere classified. Most of these codes include laterality. An example is H59.111: "Intraoperative hemorrhage and hematoma of the right eye and adnexa complicating an ophthalmic procedure."
