Chalcosis, right eye

This code describes the presence of copper deposits within the tissues of the right eye, a condition known as chalcosis. These deposits typically result from retained intraocular foreign bodies containing copper, leading to a toxic reaction affecting ocular structures.

Use this code when documentation explicitly states chalcosis affecting the right eye, often following a history of penetrating ocular trauma. Supporting documentation should include findings of copper deposition, such as a Kayser-Fleischer-like ring in the cornea or other intraocular signs of copper toxicity.

• Specify laterality; this code is for the right eye only.
• Do not confuse with siderosis (iron deposits) or other types of intraocular foreign body reactions.
• Code any associated intraocular foreign body (e.g., T15.01XA) as an additional diagnosis, if still present.
