Phlegmonous dacryocystitis of right lacrimal passage

This code represents an acute, purulent inflammation of the right lacrimal sac and surrounding tissues, often characterized by a localized collection of pus. It indicates a severe bacterial infection affecting the tear drainage system on the right side.

Use this code when documentation specifies phlegmonous dacryocystitis affecting the right lacrimal passage. This diagnosis is typically supported by findings of acute pain, swelling, redness, tenderness, and possibly purulent discharge from the right lacrimal area.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Distinguish from chronic dacryocystitis (H04.4-) or other inflammatory conditions of the lacrimal system.
• Consider an additional code for the causative organism if identified and documented.
