A18.59

What This Code Means

This code describes tuberculosis infection affecting the eye or its structures, excluding the more common forms like tuberculosis of the conjunctiva or cornea. It represents a serious infection where the tuberculosis bacteria has spread to or infected various parts of the eye.

Coding Tips

• •Verify the specific site of ocular tuberculosis involvement in the documentation, as more specific codes (A18.50-A18.58) may be more appropriate if the exact location is identified
• •Ensure tuberculosis is confirmed as the underlying cause and document whether this is pulmonary or extrapulmonary TB to support medical necessity and appropriate treatment documentation
