Primary open-angle glaucoma, bilateral, moderate stage

This code signifies a chronic eye condition characterized by elevated intraocular pressure leading to optic nerve damage and visual field loss. In this specific instance, both eyes are affected by primary open-angle glaucoma, and the disease progression is classified as moderate stage.

Apply this code when documentation confirms a diagnosis of primary open-angle glaucoma impacting both eyes, with the severity assessed as moderate. Supporting clinical notes should detail visual field defects, optic nerve changes, and intraocular pressure readings consistent with a moderate stage of the disease.

• Ensure documentation explicitly states "bilateral" involvement and "moderate stage" to support this specific code.
• Distinguish from other types of glaucoma (e.g., secondary, angle-closure) and different stages (e.g., mild, severe, unspecified).
• Always sequence glaucoma codes based on the reason for the encounter; if glaucoma is the primary reason, it should be listed first.
