Acute lacrimal canaliculitis of left lacrimal passage

This code signifies an acute inflammation of the left lacrimal canaliculus, a small tube that drains tears from the eye surface into the lacrimal sac. This condition typically presents with localized pain, redness, swelling, and discharge around the inner corner of the left eye, often accompanied by epiphora (excessive tearing). It is commonly caused by bacterial or fungal infections.

Use this code when documentation clearly indicates an acute inflammatory process affecting the left lacrimal canaliculus. This diagnosis is supported by findings such as tenderness, erythema, edema, and purulent discharge from the left punctum, along with a confirmed acute onset.

• Differentiate from chronic canaliculitis (H04.32-) based on the acute nature documented.
• Ensure laterality is clearly specified in the medical record (left vs. right vs. bilateral).
• Look for associated infectious agents if identified, which may require additional codes.
