Argentous corneal deposits, left eye

This code signifies the presence of silver-containing deposits within the cornea of the left eye. These deposits can result from prolonged systemic or topical silver exposure, leading to a grayish-blue discoloration of the cornea. The condition is typically asymptomatic but can affect vision in severe cases.

Apply this code when documentation explicitly states "argentous corneal deposits" or "argyrosis of the cornea" affecting the left eye. This diagnosis is often associated with occupational exposure to silver or long-term use of silver-containing medications. Confirmation of the laterality (left eye) is crucial for accurate coding.

• Ensure documentation specifies "argentous" or "argyrosis" to differentiate from other corneal opacities.
• Verify laterality; use the appropriate code for the right eye (H18.021) or bilateral (H18.023) if applicable.
• Consider coding any underlying cause of silver exposure, if known and documented, as a secondary diagnosis.
