Glaucoma secondary to oth eye disorders, bi, mild stage

This code signifies a form of glaucoma affecting both eyes, which has developed as a direct consequence of another underlying ocular condition. The severity of the glaucoma is classified as mild, indicating early-stage disease with minimal damage to the optic nerve or visual field.

Apply this code when documentation clearly indicates bilateral glaucoma caused by a separate eye disorder, such as uveitis, intraocular hemorrhage, or retinal detachment. The medical record must specify the mild stage of the glaucoma, often evidenced by early visual field defects or optic nerve changes.

• Ensure the documentation explicitly states "bilateral" involvement and "mild stage" to support this specific code.
• Always code the underlying eye disorder causing the secondary glaucoma first, followed by this code.
• Verify that the physician's notes differentiate this from primary open-angle glaucoma or other types of secondary glaucoma.
