Low-tension glaucoma, right eye, severe stage

This code describes a specific type of open-angle glaucoma where optic nerve damage and visual field loss occur despite intraocular pressure (IOP) being consistently within the statistically normal range. It indicates the condition affects the right eye and has progressed to a severe stage, implying significant and irreversible vision loss.

Use this code when documentation confirms a diagnosis of low-tension glaucoma affecting the right eye, with a clear indication of severe stage disease. This typically involves evidence of extensive optic nerve damage, advanced visual field defects, and normal or low IOP readings. Supporting documentation includes ophthalmology reports, visual field tests, and optic nerve head imaging.

• Ensure documentation explicitly states "low-tension" or "normal-tension" glaucoma to differentiate from other open-angle types.
• Verify the affected eye (right) and the severity stage (severe) are clearly documented.
• Do not confuse with codes for primary open-angle glaucoma (H40.11-) or other specific types of glaucoma without the "low-tension" designation.
