Pigmentary glaucoma, unspecified eye, stage unspecified

This code signifies pigmentary glaucoma, a secondary open-angle glaucoma characterized by pigment dispersion within the anterior segment of the eye, leading to increased intraocular pressure and optic nerve damage. This specific code is used when the affected eye and the stage of the glaucoma are not documented.

Apply this code when the medical record clearly indicates a diagnosis of pigmentary glaucoma but lacks specificity regarding laterality (e.g., "pigmentary glaucoma diagnosed") or the stage of the condition. Documentation supporting this code would include ophthalmological reports confirming pigmentary glaucoma without further detail.

• Avoid using this code if the laterality (right, left, bilateral) or stage of glaucoma is documented; instead, choose a more specific code.
• Frequently confused with other secondary open-angle glaucomas; ensure documentation specifies "pigmentary."
• Always query the provider for more specific information regarding laterality and stage to allow for more precise coding.
