Stenosis of right lacrimal canaliculi

This code describes a narrowing or obstruction of the small drainage channels (canaliculi) that collect tears from the right eye and direct them into the lacrimal sac. This condition impedes the normal flow of tears, often leading to epiphora (excessive tearing) and potential infections.

Use this code when documentation specifies stenosis affecting the lacrimal canaliculi of the right eye. This diagnosis is typically made based on clinical examination, irrigation, and probing of the lacrimal drainage system.

• Ensure laterality is clearly documented as "right."
• Distinguish from stenosis of the nasolacrimal duct (H04.53-) or other lacrimal gland disorders.
• Look for terms like "obstruction," "narrowing," or "stricture" of the right lacrimal canaliculus.
