H47.41

What This Code Means

This code describes damage or dysfunction of the optic chiasm (the part of the optic nerve where nerve fibers cross in the brain) that is caused by an inflammatory condition. The inflammation affects how the optic chiasm functions, potentially impacting vision.

Coding Tips

• •Always code the underlying inflammatory disorder first (such as sarcoidosis, multiple sclerosis, or other inflammatory conditions), then use H47.41 as a secondary code to indicate the optic chiasm involvement
• •Ensure documentation clearly establishes the causal relationship between the inflammatory disorder and the optic chiasm dysfunction; do not use this code if the optic chiasm disorder is unrelated to inflammation
