Primary open-angle glaucoma, left eye, moderate stage

This code identifies a chronic ocular condition characterized by progressive optic nerve damage and visual field loss due to elevated intraocular pressure, specifically affecting the left eye. It signifies that the disease has progressed to a moderate stage, indicating more significant visual impairment than early-stage glaucoma.

Apply this code when documentation confirms primary open-angle glaucoma in the patient's left eye, with clinical findings consistent with a moderate stage of the disease. This typically includes moderate visual field defects in at least one hemifield and/or optic nerve head changes indicative of moderate damage.

• Ensure laterality (left eye) is clearly documented.
• Confirm the stage of glaucoma (moderate) is explicitly stated or clearly supported by clinical findings.
• Do not use for secondary glaucoma, angle-closure glaucoma, or other specified types of glaucoma.
