Capslr glaucoma w/pseudxf lens, unsp eye, moderate stage

This code describes a specific type of secondary open-angle glaucoma characterized by the accumulation of pseudoexfoliative material on the lens and other ocular structures, leading to elevated intraocular pressure and optic nerve damage. The "moderate stage" indicates a defined level of visual field loss or optic nerve damage, as per clinical staging guidelines.

Assign this code when documentation confirms a diagnosis of capsular glaucoma (also known as pseudoexfoliation glaucoma) affecting an unspecified eye, and the disease progression is explicitly noted as moderate. Supporting documentation should include findings of pseudoexfoliative material, elevated intraocular pressure, and evidence of moderate glaucomatous optic neuropathy or visual field defects.

• Ensure the documentation specifies "moderate stage" rather than mild, severe, or unspecified stage.
• Differentiate from primary open-angle glaucoma (H40.10-H40.12) and other secondary glaucomas.
• If the affected eye is known, use the more specific code for right (H40.141-) or left (H40.142-) eye.
