Inflammation (infection) of postprocedural bleb, stage 3

This code describes a severe inflammatory or infectious process affecting a filtering bleb, which is a surgically created blister-like structure on the sclera, typically formed after glaucoma surgery (e.g., trabeculectomy). Stage 3 indicates a significant, advanced stage of inflammation or infection, often involving the entire bleb and potentially extending to the surrounding ocular tissues.

Use this code when documentation clearly indicates a post-surgical bleb is inflamed or infected, and the severity is explicitly noted as "stage 3" or described with clinical findings consistent with advanced inflammation/infection (e.g., extensive bleb involvement, hypopyon, vitreous involvement). This code is appropriate for complications arising from glaucoma filtration surgery.

• Ensure the documentation specifies "stage 3" or provides clinical details that unequivocally support this advanced stage of inflammation/infection.
• Do not confuse this with less severe stages of bleb inflammation or infection; specific codes exist for stages 1 and 2.
• Always sequence this code after the primary code for the underlying glaucoma or the reason for the original surgery, if applicable and still being treated.
