Neonatal obstruction of right nasolacrimal duct

This code signifies a blockage in the tear drainage system of the right eye in a newborn. This obstruction prevents tears from draining properly, leading to excessive tearing (epiphora) and sometimes discharge or infection.

Apply this code when documentation clearly indicates a diagnosis of nasolacrimal duct obstruction affecting the right eye in a neonate (birth to 28 days of age). This is typically diagnosed based on clinical examination, often presenting with persistent tearing or matting of the eyelashes.

• Ensure the documentation specifies "right" eye; laterality is crucial for accurate coding.
• Verify the patient's age falls within the neonatal period.
• Distinguish from congenital dacryocystitis, which may involve infection of the lacrimal sac.
