J01.21

What This Code Means

This is an infection of the ethmoid sinuses (small air-filled spaces in the bones between the eyes and nose) that comes back repeatedly. The patient experiences inflammation and buildup of fluid in these sinuses, causing symptoms like facial pain, nasal congestion, and drainage.

Coding Tips

• •The 'recurrent' designation in J01.21 means the patient has had multiple episodes of ethmoidal sinusitis; ensure documentation supports this pattern of repeated infections rather than a single acute episode
• •Verify laterality if applicable and check for any associated conditions (like nasal polyps or allergies) that may be coded separately to capture the complete clinical picture
