ICD-10 Code H04.53 – Neonatal obstruction of nasolacrimal duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.53 – Neonatal obstruction of nasolacrimal duct
What it is
This code identifies blocked tear drainage in a newborn, usually from incomplete opening of the nasolacrimal duct. It is used when the condition is present in the neonatal period and documented as an obstruction.
Clinical signs
Typical findings include excessive tearing, sticky discharge, and mild crusting around one or both eyes. Clinical features vary; refer to documentation if the chart does not clearly describe a neonatal tear duct obstruction.
When to use this code
Use H04.53 when the provider documents neonatal nasolacrimal duct obstruction, blocked tear duct, or congenital tear drainage delay in a newborn. You should also use it when the record links tearing or discharge to this specific neonatal diagnosis. If the note is nonspecific, check documentation before assigning the code.
Do not use for
Do not use this code for acquired tear duct obstruction in older infants, children, or adults. It is also incorrect for eye discharge without a documented nasolacrimal duct obstruction.
Coding tip
Assign the code only when the provider clearly documents a neonatal tear duct obstruction, not just watery eyes.
