Glaucoma secondary to oth eye disord, right eye, mild stage

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, resulting from a pre-existing ocular condition other than those explicitly classified elsewhere. The glaucoma is in its early stages, characterized by minimal optic nerve damage and visual field loss.

Use this code when documentation clearly indicates secondary glaucoma affecting the right eye, caused by an underlying eye disorder such as uveitis, intraocular hemorrhage, or retinal detachment, and the stage is specified as mild. Supporting documentation should include ophthalmologist notes detailing the secondary nature, the specific underlying eye disorder, and the mild severity of the glaucoma.

• Ensure the underlying eye disorder causing the secondary glaucoma is also coded.
• Verify laterality (right eye) and the specified stage (mild) are clearly documented.
• Distinguish from primary open-angle glaucoma (H40.1x) or glaucoma due to trauma (H40.3x).
