2026 ICD-10-CM Diagnosis Code H59.43 – Inflammation (infection) of postprocedural bleb, stage 3
What it is
H59.43 identifies inflammation or infection involving a postprocedural bleb, specifically stage 3. Use it when documentation clearly states this complication after an eye procedure.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note bleb redness, tenderness, discharge, or other signs of infection affecting the surgical site.
When to use this code
Use H59.43 when the provider documents stage 3 inflammation or infection of a postprocedural bleb and links it to prior ocular surgery. It is appropriate for postoperative complication coding when the bleb is the affected structure. Check documentation if the stage or infectious nature is unclear.
Do not use for
Do not use this code for uncomplicated postprocedural blebs or for eye infections not involving a bleb. If the record does not specify stage 3, check documentation.
Coding tip
Confirm both the postprocedural bleb complication and the stage before assigning H59.43.
