ICD-10 Code H59.013 – Keratopathy (bullous aphakic) following cataract surgery, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.013 – Keratopathy (bullous aphakic) following cataract surgery, bilateral
What it is
This code identifies bullous aphakic keratopathy affecting both eyes after cataract surgery. It refers to corneal edema with blister-like changes in an eye that no longer has its natural lens.
Clinical signs
Typical findings include corneal swelling, epithelial bullae, eye pain, tearing, and blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H59.013 when the record clearly states bilateral bullous aphakic keratopathy as a postoperative complication of cataract surgery. You should link the condition to the prior surgery in the documentation. If the chart does not specify bilateral involvement or postoperative causation, check documentation.
Do not use for
Do not use this code for corneal edema or keratopathy without aphakia or without a cataract-surgery history. Do not assign it when the side is unspecified or when the condition is unrelated to surgery.
Coding tip
Confirm both laterality and the postoperative cataract-surgery link before you code.
