Inflammation (infection) of postprocedural bleb, stage 1

This code signifies an inflammatory or infectious process affecting a bleb created during a glaucoma filtering surgery, specifically when the condition is in its initial, less severe stage. A bleb is a fluid-filled blister on the surface of the eye, essential for the success of these procedures in lowering intraocular pressure.

Apply this code when documentation indicates inflammation or infection of a post-surgical bleb, and the physician explicitly states "stage 1" or describes early, mild signs such as localized redness, discomfort, or minimal discharge without significant vision compromise or systemic involvement. This code is appropriate for initial presentations of bleb-related complications following glaucoma surgery.

• Ensure the documentation clearly specifies "stage 1" or equivalent mild presentation of inflammation/infection.
• Distinguish from more severe bleb infections (e.g., endophthalmitis), which would require different codes.
• Always sequence this code after the primary glaucoma diagnosis and any relevant procedure codes.
