Glaucoma sec to oth eye disord, r eye, indeterminate stage

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, resulting from an underlying ocular condition other than trauma, inflammation, or medication. The specific stage of glaucoma progression is not definitively determined at the time of diagnosis.

Use this code when documentation clearly indicates secondary glaucoma in the right eye due to another eye disorder (e.g., retinal detachment, intraocular tumor, severe myopia) and the stage of the glaucoma is not yet classified. Supporting documentation should specify the secondary nature of the glaucoma and the affected eye.

• Ensure the documentation explicitly states "right eye" and identifies the underlying "other eye disorder" causing the glaucoma.
• Do not use this code if the secondary glaucoma is due to trauma (H40.3-), inflammation (H40.4-), or drugs (H40.6-).
• If the stage of glaucoma is known (e.g., mild, moderate, severe, absolute), use the more specific stage code instead of "indeterminate."
