Glaucoma secondary to eye inflammation, unsp eye, stage unsp

This code signifies glaucoma that has developed as a direct consequence of inflammation within the eye, without specifying which eye is affected or the severity/stage of the glaucoma. It indicates a secondary form of glaucoma where the primary etiology is an inflammatory process, such as uveitis or iritis, leading to increased intraocular pressure.

Use this code when documentation clearly links glaucoma to a preceding or co-existing ocular inflammatory condition, but the specific eye (right, left, or bilateral) is not documented, and the stage of glaucoma is also not specified. This code is appropriate when the physician explicitly states "glaucoma secondary to inflammation" or similar phrasing, and further details are absent.

• Always attempt to clarify the affected eye and the stage of glaucoma with the provider for more specific coding (e.g., H40.41X_ or H40.42X_).
• Code the underlying inflammatory condition (e.g., uveitis, iritis) first, followed by this code, to accurately reflect the etiology.
• Avoid using this code if the glaucoma is primary open-angle, angle-closure, or congenital, as those have their own distinct code categories.
