Stenosis of left lacrimal canaliculi

This code signifies a narrowing or obstruction of the left lacrimal canaliculus, the small tube that drains tears from the eye into the lacrimal sac. This condition impedes normal tear drainage, often leading to epiphora (excessive tearing) and potential recurrent infections.

Apply this code when documentation explicitly states stenosis or obstruction of the left lacrimal canaliculus. This is commonly diagnosed during an ophthalmological exam, often following a Dacryocystography (DCG) or lacrimal irrigation.

• Ensure laterality is clearly documented as "left" to support this specific code.
• Distinguish from congenital stenosis (Q10.5) or stenosis of the nasolacrimal duct (H04.55-).
• Consider sequencing with codes for associated symptoms like epiphora (H04.20-) or dacryocystitis (H04.3-).
