Pigmentary glaucoma, bilateral, moderate stage

This code signifies a diagnosis of pigmentary glaucoma affecting both eyes, where the disease has progressed to a moderate stage. Pigmentary glaucoma is a form of open-angle glaucoma characterized by pigment dispersion from the iris, which obstructs the trabecular meshwork and elevates intraocular pressure.

Use this code when documentation confirms a bilateral diagnosis of pigmentary glaucoma and the ophthalmologist has explicitly staged the condition as moderate. This typically involves visual field defects in at least one hemifield, but not extending to central fixation in both, and/or optic nerve damage consistent with moderate disease.

• Ensure the medical record clearly specifies "bilateral" involvement and a "moderate" stage for pigmentary glaucoma.
• Do not confuse with other types of glaucoma (e.g., primary open-angle glaucoma) or different stages (e.g., mild, severe, unspecified).
• Always review the ophthalmologist's notes for visual field test results, optic nerve head assessment, and intraocular pressure readings to confirm the stage.
