Acquired stenosis of bilateral nasolacrimal duct

This code signifies a narrowing or obstruction of both tear drainage ducts that developed after birth. This condition typically leads to epiphora (excessive tearing) and may be associated with recurrent infections (dacryocystitis) due to impaired tear outflow.

Apply this code when documentation clearly indicates an acquired, bilateral obstruction of the nasolacrimal ducts. This is often diagnosed through clinical examination, irrigation, or dacryocystography, and is distinct from congenital blockages.

• Ensure documentation specifies "acquired" and "bilateral" to support this code.
• Distinguish from congenital nasolacrimal duct obstruction (e.g., Q10.5x).
• Code any associated dacryocystitis (e.g., H04.3x) separately, if present.
