Implant cysts of iris, ciliary body or ant chamber, bi

This code describes the presence of benign, fluid-filled sacs or epithelial growths located in the iris, ciliary body, or anterior chamber of both eyes. These cysts are typically a result of trauma, surgery, or inflammation where epithelial cells become entrapped within the ocular tissues. They can be congenital but are more commonly acquired.

Use this code when documentation clearly indicates the diagnosis of implantation cysts affecting both eyes, specifically within the iris, ciliary body, or anterior chamber. This diagnosis is often made during a slit-lamp examination or other ophthalmic imaging. The physician's notes should specify the bilateral involvement and the location of the cysts.

• Ensure the documentation explicitly states "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish implantation cysts from other types of ocular cysts (e.g., primary cysts, parasitic cysts) as they have different ICD-10-CM codes.
• Code any underlying cause or associated conditions, such as previous ocular trauma or surgery, if documented and relevant.
