Neonatal obstruction of unspecified nasolacrimal duct

This code describes a blockage of the tear drainage system in a newborn, specifically the nasolacrimal duct, where the exact location or cause of the obstruction is not specified. This condition typically presents as persistent tearing and discharge from the eye due to the inability of tears to drain properly into the nasal cavity.

Use this code when documentation indicates a neonate (birth to 28 days old) has an obstructed nasolacrimal duct, and the physician has not specified laterality (right, left, or bilateral) or the specific type of obstruction. This code is appropriate when the clinical picture points to a congenital blockage, often presenting as epiphora and conjunctivitis.

• Avoid using this code if the laterality (right, left, or bilateral) is documented; instead, select a more specific code from the H04.53 series.
• Ensure the patient's age is within the neonatal period (0-28 days) for appropriate use of this code.
• If the obstruction is acquired or occurs in an older infant/child, a different code from the H04.5 series would be more appropriate.
