Inflammation (infection) of postprocedural bleb, stage 2

This code signifies an inflammatory or infectious process affecting a post-surgical bleb, specifically reaching stage 2 severity. A bleb is a fluid-filled sac, often created intentionally during glaucoma surgery (e.g., trabeculectomy) to facilitate aqueous humor drainage. Stage 2 indicates a moderate level of inflammation or infection, typically with some clinical signs but not yet severe vision compromise or endophthalmitis.

Use this code when documentation clearly indicates inflammation or infection of a bleb following an ocular procedure, and the physician specifies or implies a stage 2 severity. This often involves symptoms like redness, discharge, bleb thinning, or early signs of blebitis, but without advanced complications like hypotony maculopathy or frank endophthalmitis. Supporting documentation would include ophthalmology notes detailing the bleb's appearance, patient symptoms, and the physician's assessment of the inflammatory/infectious stage.

• Ensure the documentation specifies "stage 2" or provides sufficient detail to infer this stage, differentiating it from stage 1 (mild) or stage 3 (severe).
• Do not confuse this with other postprocedural complications like bleb leak (H59.41) or hypotony (H44.4-).
• If an infectious agent is identified, code the infection first, followed by this code to specify the site and stage.
