Filtering (vitreous) bleb after glaucoma surgery status

This code indicates the presence of a functioning bleb following glaucoma surgery, specifically a filtering bleb in the vitreous. This bleb is an intentional surgical outcome designed to facilitate the drainage of aqueous humor, thereby reducing intraocular pressure. It signifies a stable, post-operative state where the bleb is performing its intended function.

Use this code when documenting a patient's status after glaucoma surgery, where a filtering bleb is present and functioning as expected. This is appropriate for routine follow-up visits where the bleb is examined and confirmed to be stable and effective in maintaining intraocular pressure. It should be used when there are no complications or active issues related to the bleb itself, such as infection or dysfunction.

• Do not use this code if the bleb is inflamed or infected; instead, refer to H59.4- for postprocedural bleb inflammation/infection.
• This code is for the status of a functioning bleb, not for complications or problems with the bleb.
• Always code in conjunction with the underlying glaucoma diagnosis (e.g., H40.-) and any other relevant post-operative status codes.
