Miotic pupillary cyst, left eye

This code describes a cyst located on the iris or ciliary body of the left eye that causes the pupil to constrict. These cysts are typically benign and can be congenital or acquired, often presenting as a small, dark lesion on the iris. They may or may not cause visual disturbances.

Use this code when documentation specifies a miotic pupillary cyst affecting the left eye. This diagnosis is typically made during an ophthalmological examination, often with slit-lamp biomicroscopy. Supporting documentation should clearly indicate the laterality and the nature of the cyst.

• Ensure laterality is accurately documented; do not use unspecified codes if left or right eye is known.
• Distinguish from other iris cysts (e.g., pigment epithelial cysts) that do not specifically cause miosis.
• Code any associated visual disturbances or complications separately, if documented.
