Acquired stenosis of right nasolacrimal duct

This code describes a narrowing or obstruction of the right nasolacrimal duct that developed after birth, leading to impaired tear drainage. This acquired condition can result in epiphora (excessive tearing), recurrent conjunctivitis, or dacryocystitis (inflammation of the lacrimal sac).

Use this code when documentation specifies an acquired, non-congenital stenosis affecting the right nasolacrimal duct. This diagnosis is typically supported by clinical examination findings of epiphora, a positive fluorescein dye disappearance test, or imaging studies confirming the obstruction.

• Ensure documentation clearly specifies "acquired" to differentiate from congenital forms.
• Verify laterality (right eye) is explicitly stated; separate codes exist for left and bilateral involvement.
• Consider additional codes for any associated conditions, such as dacryocystitis (H04.3-) or conjunctivitis (H10.-).
