About the H59 Code Range
ICD-10 code range H59 covers intraoperative and postprocedural complications of the eye and its surrounding structures that are not classified elsewhere. This range is specifically used to identify disorders that arise during or after eye surgeries, such as cataract procedures or other ophthalmic operations.
The H59 codes include a variety of complications following cataract surgery, such as bullous aphakic keratopathy (also known as aphakic corneal edema or bullous keratopathy), cataract (lens) fragments left in the eye, and cystoid macular edema—all categorized with laterality (right, left, bilateral, or unspecified). It also covers intraoperative hemorrhage and hematoma, accidental puncture and laceration during procedures, as well as postprocedural hemorrhage, hematoma, and seroma of the eye and adnexa. Additionally, H59.4 focuses on inflammation or infection of the postprocedural bleb, commonly referred to as blebitis or postoperative endophthalmitis. The range further includes scarring after retinal detachment surgery and other intra- and postprocedural complications such as lens capsule rupture, filtering bleb leaks, irregular astigmatism, and various infections or injuries specific to eye-related surgeries. Utilizing these codes helps medical coders precisely classify complications like aphakic bullous keratopathy, cystoid macular edema, or postoperative hemorrhage, aiding in detailed medical documentation and patient care management.
