Neonatal obstruction of bilateral nasolacrimal duct

This code signifies a blockage of the tear drainage system in both eyes of a newborn. This condition prevents tears from draining properly, often leading to excessive tearing (epiphora) and sometimes discharge or infection. It is a congenital anomaly affecting the nasolacrimal ducts.

Apply this code when documentation explicitly states bilateral nasolacrimal duct obstruction in a neonate (birth to 28 days old). This is typically diagnosed by an ophthalmologist or pediatrician observing persistent tearing or discharge from both eyes shortly after birth. Documentation should specify the bilateral nature of the obstruction.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, use a code for unilateral obstruction.
• Confirm the patient's age falls within the neonatal period for accurate code selection.
• Do not confuse with codes for dacryocystitis unless an infection is also documented and separately coded.
