Pigmentary glaucoma, bilateral, mild stage

This code signifies a diagnosis of pigmentary glaucoma affecting both eyes, where the condition is classified as mild. Pigmentary glaucoma is a secondary open-angle glaucoma characterized by the dispersion of pigment from the iris, which then clogs the trabecular meshwork, leading to increased intraocular pressure and optic nerve damage. The "mild stage" indicates early disease with minimal visual field loss and optic nerve changes.

Use this code when documentation clearly states bilateral pigmentary glaucoma and specifies a mild stage of the disease. This typically applies to patients presenting with early signs of pigment dispersion syndrome progressing to glaucoma, or those diagnosed during routine ophthalmic examinations. Documentation should include findings such as pigment deposition, elevated intraocular pressure, and early glaucomatous optic neuropathy or visual field defects.

• Ensure documentation explicitly states "bilateral" and "mild stage" for accurate coding.
• Do not use this code if only one eye is affected or if the stage is moderate or severe; specific codes exist for those scenarios.
• Always sequence this code after any underlying cause or associated conditions, if applicable, and consider codes for visual impairment if present.
