ICD-10 Code H04.512 – Dacryolith of left lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.512 – Dacryolith of left lacrimal passage
What it is
This code identifies a dacryolith, or stone-like concretion, located in the left lacrimal passage. It is used when documentation specifies a left-sided obstruction or deposit in the tear drainage system.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see tearing, discharge, or symptoms of blocked tear drainage on the left side, with the finding confirmed by exam or imaging.
When to use this code
Use H04.512 when the provider documents a dacryolith in the left lacrimal passage, including cases described as a tear duct stone or concretion. Code it when the left side is clearly identified in the record. If laterality is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for general epiphora, dacryocystitis, or unspecified lacrimal obstruction unless a dacryolith is documented. Do not assume laterality when the record does not specify the left side.
Coding tip
Verify both the finding and laterality in the note, because H04.512 is specific to a left-sided dacryolith.
