H04.553

What This Code Means

This condition occurs when both tear drainage ducts (one on each side of the nose) become abnormally narrowed or blocked, preventing tears from draining properly from the eyes. This is an acquired condition, meaning it developed over time rather than being present from birth.

Coding Tips

• •Verify that the stenosis is bilateral (affecting both sides) before assigning this code; if only one side is affected, use the unilateral code H04.551 instead
• •Document whether this is a primary acquired stenosis or secondary to trauma, inflammation, or previous surgery, as this may affect clinical management and documentation clarity
