Pigmentary glaucoma, right eye, severe stage

This code signifies a form of secondary open-angle glaucoma characterized by pigment dispersion, specifically affecting the right eye and having progressed to a severe stage. Pigmentary glaucoma occurs when pigment granules from the iris are released and clog the trabecular meshwork, obstructing aqueous humor outflow and increasing intraocular pressure.

Use this code when documentation clearly indicates pigmentary glaucoma in the patient's right eye, and the ophthalmologist has assessed and documented the severity as "severe." This typically involves significant visual field loss, advanced optic nerve damage, or uncontrolled intraocular pressure despite maximum tolerated medical therapy.

• Ensure the medical record explicitly states "pigmentary glaucoma" and specifies the "right eye" and "severe stage."
• Do not use this code for pigment dispersion syndrome without glaucoma, or for other types of secondary open-angle glaucoma.
• Confirm the laterality (right eye) and severity (severe stage) are clearly documented to support this specific code.
