ICD-10 Code H04.519 – Dacryolith of unspecified lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.519 – Dacryolith of unspecified lacrimal passage
What it is
H04.519 identifies a dacryolith, or stone-like concretion, in an unspecified lacrimal passage. Use it when the record documents a lacrimal duct stone but does not name the exact passage.
Clinical signs
Clinical features vary; refer to documentation. Commonly, a dacryolith may be associated with tearing, irritation, or obstruction of tear drainage, but the record should support the diagnosis.
When to use this code
Use H04.519 when the provider clearly documents a dacryolith in the lacrimal system and the affected passage is not specified. This code fits outpatient, inpatient, or consult notes that confirm the finding without further anatomic detail.
If documentation only mentions tearing, blockage, or suspected obstruction without naming a dacryolith, check documentation before assigning this code. Code the more specific lacrimal disorder if the record identifies a different condition.
Do not use for
Do not use this code for general epiphora, dacryocystitis, or other lacrimal disorders unless a dacryolith is documented. Do not assign it when the stone is located in a different anatomic site.
Coding tip
Query for the exact lacrimal passage when the note says “dacryolith” but does not specify location.
