Stenosis of bilateral lacrimal canaliculi

This code signifies a narrowing or obstruction of both lacrimal canaliculi, the small ducts that drain tears from the puncta into the lacrimal sac. This bilateral condition impedes normal tear drainage, often leading to epiphora (excessive tearing) and potential recurrent infections.

Apply this code when documentation explicitly states bilateral stenosis or obstruction of the lacrimal canaliculi. This typically occurs in cases of chronic dacryocystitis, trauma, inflammation, or following certain ophthalmic procedures affecting both tear drainage systems.

• Ensure documentation specifies bilateral involvement; otherwise, a laterality-specific code should be used.
• Distinguish from stenosis of the nasolacrimal duct, which has separate codes.
• Consider sequencing with codes for underlying causes (e.g., chronic dacryocystitis) if applicable.
