Exudative cysts of iris or anterior chamber, left eye

This diagnosis code signifies the presence of fluid-filled sacs (cysts) that have formed due to inflammation or leakage within the iris or the anterior chamber of the left eye. These cysts are characterized by their exudative nature, meaning they contain fluid that has seeped out of blood vessels or tissues.

Apply this code when documentation explicitly states an exudative cyst affecting the iris or anterior chamber of the left eye. Supporting clinical notes would typically describe the cyst's location, its exudative characteristics, and laterality. This code is appropriate for both initial encounters and subsequent follow-up visits for this specific condition.

• Ensure the documentation clearly specifies "exudative" to differentiate from other cyst types (e.g., degenerative, implantation).
• Verify laterality; this code is specific to the left eye. Use the appropriate code for the right eye or bilateral involvement.
• Consider any underlying conditions causing the exudation and code them as primary or secondary diagnoses as appropriate.
