Miotic pupillary cyst, right eye

This code describes a cyst located on the iris or ciliary body of the right eye that causes the pupil to constrict. These cysts are typically benign and can be congenital or acquired, often presenting as a small, dark, spherical lesion. The miotic effect refers to the sustained constriction of the pupil due to the cyst's presence or pressure.

Use this code when documentation clearly indicates a diagnosis of a pupillary cyst affecting the right eye, specifically noting its miotic effect. This diagnosis is typically made during an ophthalmological examination, often involving slit-lamp biomicroscopy. Supporting documentation should include the laterality (right eye) and the observed pupillary constriction.

• Ensure the documentation specifies "miotic" to differentiate from other types of pupillary cysts.
• Verify laterality; separate codes exist for the left eye and bilateral involvement.
• Do not confuse with codes for iris atrophy or other pupillary abnormalities that are not cystic in nature.
