Primary open-angle glaucoma, right eye, mild stage

This code signifies a chronic, progressive optic neuropathy characterized by an open anterior chamber angle and elevated intraocular pressure, leading to visual field loss in the right eye. The "mild stage" indicates early damage to the optic nerve with corresponding minimal visual field defects.

Apply this code when documentation confirms a diagnosis of primary open-angle glaucoma affecting the right eye, and the ophthalmologist or optometrist has staged the condition as mild. Supporting documentation should include visual field test results, optic nerve head assessment (e.g., OCT, fundus photography), and intraocular pressure readings.

• Ensure laterality (right eye) and stage (mild) are clearly documented by the provider.
• Do not confuse with other types of glaucoma (e.g., secondary, angle-closure) or unspecified glaucoma.
• Code also any associated visual impairment or blindness if documented, using the appropriate H54.x codes.
