H21.222

What This Code Means

This code describes a condition where the ciliary body (a part of the eye that helps control focus and produces fluid) is deteriorating or breaking down in the left eye. This degeneration can affect the eye's ability to focus properly and maintain normal eye pressure.

Coding Tips

• •Ensure documentation specifies 'left eye' to justify the laterality code '2' in the fifth character; if both eyes are affected, code each eye separately with appropriate laterality indicators
• •Verify that the degeneration is not secondary to another condition (such as trauma, inflammation, or surgery); if it is, consider coding the underlying cause as the primary diagnosis
