Pigmentary glaucoma, right eye, stage unspecified

This code describes pigmentary glaucoma affecting the right eye, where the stage of the glaucoma (e.g., mild, moderate, severe) has not been documented by the physician. Pigmentary glaucoma is a secondary open-angle glaucoma characterized by the dispersion of pigment granules from the iris, which then deposit in the trabecular meshwork, obstructing aqueous humor outflow and increasing intraocular pressure.

Use this code when documentation explicitly states "pigmentary glaucoma" in the right eye, and there is no mention of the severity or stage of the condition. This code is appropriate for initial diagnoses or follow-up visits where the stage remains undetermined or unrecorded. Supporting documentation would include an ophthalmologist's or optometrist's notes detailing the diagnosis of pigmentary glaucoma in the right eye without specifying its stage.

• Ensure the documentation clearly specifies "right eye" and "pigmentary glaucoma."
• Do not use this code if the stage of glaucoma (e.g., mild, moderate, severe, indeterminate) is documented; instead, select the appropriate code that includes the stage.
• Verify laterality carefully; codes exist for the left eye, bilateral, and unspecified eye.
