Glaucoma secondary to oth eye disorders, bi, moderate stage

This code signifies a form of glaucoma that develops as a complication of another underlying eye condition, affecting both eyes, and has progressed to a moderate stage of severity. This secondary glaucoma is characterized by elevated intraocular pressure leading to optic nerve damage and visual field loss, directly attributable to a primary ocular disease.

Apply this code when documentation clearly indicates bilateral glaucoma resulting from another specified eye disorder (e.g., uveitis, intraocular hemorrhage, retinal detachment) and the ophthalmologist has staged the condition as moderate. Supporting documentation must specify the underlying ocular condition causing the glaucoma and confirm the moderate stage of glaucomatous damage in both eyes.

• Ensure the medical record explicitly identifies the "other eye disorder" causing the secondary glaucoma; this underlying condition should be coded first.
• Verify that both eyes are affected and that the moderate stage is clearly documented, often based on visual field defects or optic nerve damage.
• Distinguish from primary open-angle glaucoma or other specific types of secondary glaucoma (e.g., pigmentary, pseudoexfoliative) which have their own distinct codes.
