ICD-10 Code H04.51 – Dacryolith (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.51 – Dacryolith
What it is
Dacryolith means a stone or concretion in the tear drainage system, usually within the lacrimal passages. It can obstruct tear flow and irritate the eye area.
Clinical signs
Patients may have tearing, discharge, or recurrent blockage of the tear duct. Clinical features vary; refer to documentation for the exact site and associated findings.
When to use this code
Use H04.51 when the provider documents a dacryolith affecting the lacrimal drainage system. You may also use it when the note describes a tear duct stone, lacrimal concretion, or similar confirmed finding. Check documentation if the record only mentions nonspecific epiphora or infection.
Do not use for
Do not use this code for general tearing without a documented dacryolith. Do not assign it when the record describes another lacrimal disorder or an unspecified obstruction.
Coding tip
Code the documented lacrimal stone specifically, and verify laterality or associated obstruction only if the record supports it.
