ICD-10 Code H59.41 – Inflammation (infection) of postprocedural bleb, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.41 – Inflammation (infection) of postprocedural bleb, stage 1
What it is
This code identifies inflammation or infection involving a postprocedural bleb after an eye procedure. Use it when the record specifically documents stage 1 involvement of the bleb.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe a red, tender, or irritated bleb with signs of inflammation or infection after surgery.
When to use this code
Use H59.41 when the ophthalmology note clearly states postprocedural bleb inflammation or infection and identifies it as stage 1. You should code it for postoperative follow-up visits when the complication is the reason for care. If the stage is not documented, check documentation before assigning the code.
Do not use for
Do not use this code for uncomplicated postprocedural blebs or for other postoperative eye complications. Do not assume the diagnosis if the record only mentions irritation without confirming inflammation or infection.
Coding tip
Confirm both the bleb complication and the documented stage before coding.
