ICD-10 Code H04.533 – Neonatal obstruction of bilateral nasolacrimal duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.533 – Neonatal obstruction of bilateral nasolacrimal duct
What it is
This code identifies a newborn with blockage of both tear drainage ducts. It means tears cannot drain normally from either eye because the nasolacrimal ducts are obstructed.
Clinical signs
Typical findings include tearing, crusting, or discharge from both eyes in a neonate. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents bilateral nasolacrimal duct obstruction in the neonatal period. It fits newborn eye drainage problems described as congenital or present at birth. If laterality is not stated, check documentation before assigning this code.
Do not use for
Do not use it for acquired tear duct obstruction, unilateral obstruction, or nonspecific eye discharge without a documented diagnosis. Check documentation.
Coding tip
Verify both neonatal status and bilateral involvement in the provider note before coding H04.533.
