ICD-10 Code H04.532 – Neonatal obstruction of left nasolacrimal duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.532 – Neonatal obstruction of left nasolacrimal duct
What it is
This code identifies blockage of the left tear drainage duct in a newborn. It is used when the obstruction is present at birth or in the neonatal period and affects the left side only.
Clinical signs
Typical findings include excessive tearing from the left eye and possible discharge from the punctum or eyelids. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states neonatal obstruction of the left nasolacrimal duct, congenital dacryostenosis, or similar wording limited to the left side. You may also use it when the provider documents persistent tearing in a newborn due to left duct blockage. Check documentation if laterality is unclear.
Do not use for
Do not use this code for right-sided or bilateral nasolacrimal obstruction, or for acquired tear duct obstruction in older patients. Do not assume the diagnosis from tearing alone without provider confirmation.
Coding tip
Verify laterality and neonatal status in the note before assigning H04.532.
