Neonatal obstruction of left nasolacrimal duct

This code describes a blockage of the nasolacrimal duct in a newborn, specifically affecting the left eye. This obstruction prevents proper drainage of tears, leading to epiphora (excessive tearing) and potential secondary infections. It is a congenital condition, meaning it is present at birth.

Use this code for a neonate (birth to 28 days of age) diagnosed with a congenital obstruction of the left nasolacrimal duct. Documentation should clearly state the laterality (left eye) and the patient's age or status as a newborn. This code is appropriate when the condition is identified and treated during the neonatal period.

• Ensure documentation specifies "neonatal" or "newborn" and the laterality (left).
• Distinguish from acquired nasolacrimal duct obstructions, which would use different codes.
• Consider sequencing with codes for any associated symptoms (e.g., epiphora, conjunctivitis) if documented as separate conditions.
