Pigmentary glaucoma, right eye, indeterminate stage

This code signifies pigmentary glaucoma affecting the right eye, where the stage of the disease progression has not been definitively determined. Pigmentary glaucoma is a secondary open-angle glaucoma characterized by the dispersion of pigment from the iris, which then obstructs the trabecular meshwork, leading to increased intraocular pressure and optic nerve damage.

Apply this code when documentation specifies pigmentary glaucoma in the right eye, but the ophthalmologist has not yet categorized the severity or stage (e.g., mild, moderate, severe). This is appropriate for initial diagnoses or when further evaluation is needed to stage the condition. Documentation must clearly indicate "right eye" and "indeterminate stage."

• Ensure the medical record explicitly states "right eye" and "indeterminate stage" for pigmentary glaucoma.
• Do not use this code if a specific stage of pigmentary glaucoma (e.g., mild, moderate, severe) is documented; instead, select the appropriate staged code.
• Consider sequencing this code after any underlying systemic conditions if they are directly contributing to the glaucoma.
