ICD-10 Code H04.513 – Dacryolith of bilateral lacrimal passages (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.513 – Dacryolith of bilateral lacrimal passages
What it is
This code identifies a dacryolith, or stone-like deposit, in both lacrimal passages. It means the tear drainage system on each side is obstructed by calcified or debris-like material.
Clinical signs
Typical findings include tearing, intermittent blockage, and possible discomfort around the tear ducts. Clinical features vary; refer to documentation if the record does not clearly describe bilateral involvement.
When to use this code
Use H04.513 when the clinician documents dacryoliths in both lacrimal passages or bilateral tear-duct stones. It also applies when imaging, examination, or surgical findings confirm bilateral obstruction by dacryoliths. If the note only says “tear duct stone” without laterality, check documentation.
Do not use for
Do not use this code for unilateral dacryoliths or for nonspecific epiphora without documented dacryoliths. Do not assign it when the record describes a different lacrimal disorder. Check documentation.
Coding tip
Verify laterality in the operative report or assessment, because H04.513 is specific to bilateral lacrimal passages.
