Other specified glaucoma

This code represents a form of glaucoma that does not fit into the more specific categories of primary open-angle, angle-closure, or secondary glaucomas. It encompasses various less common or atypical presentations of the disease where elevated intraocular pressure leads to optic nerve damage and visual field loss.

Use this code when the physician's documentation clearly states a diagnosis of glaucoma that is not otherwise specified or falls into a distinct "other" category. This includes conditions like pigmentary glaucoma, pseudoexfoliation glaucoma (when not specified as secondary), or glaucoma associated with ocular trauma or inflammation where a more specific secondary code isn't applicable. Documentation should detail the type of glaucoma and rule out more common forms.

• Do not use this code if a more specific glaucoma code (e.g., H40.1x for primary open-angle glaucoma) can be assigned.
• Always review the medical record for specific etiologies or associated conditions that might warrant a more precise code or an additional secondary diagnosis.
• Ensure the documentation clearly differentiates this "other specified" glaucoma from "unspecified" glaucoma (H40.9x), which should only be used when no further detail is available.
