Parasitic cyst of iris, ciliary body or ant chamber, bi

This code signifies the presence of a parasitic cyst affecting both eyes, specifically located within the iris, ciliary body, or anterior chamber. These cysts are typically caused by helminthic infections and can lead to inflammation, vision impairment, or glaucoma.

Use this code when documentation clearly indicates a parasitic cyst affecting the anterior segment of both eyes. This diagnosis is often supported by ophthalmological examination findings, imaging studies, and sometimes serological tests or biopsy results confirming parasitic etiology.

• Ensure documentation specifies bilateral involvement; otherwise, use the appropriate unilateral code.
• Distinguish from non-parasitic cysts of the iris, ciliary body, or anterior chamber, which have different ICD-10-CM codes.
• Code any associated conditions, such as uveitis or glaucoma, in addition to the parasitic cyst.
