ICD-10 Code H04.511 – Dacryolith of right lacrimal passage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.511 – Dacryolith of right lacrimal passage
What it is
H04.511 identifies a dacryolith, or stone, located in the right lacrimal passage. Use it when documentation specifies a calculus or concretion obstructing the right tear drainage pathway.
Clinical signs
Typical findings include tearing, irritation, and possible blockage of tear drainage on the right side. Clinical features vary; refer to documentation for confirmed obstruction or stone in the lacrimal passage.
When to use this code
Use this code when the record clearly states a dacryolith in the right lacrimal passage, including imaging or procedural confirmation. It also fits when the clinician documents a right-sided lacrimal stone causing epiphora or obstruction. Check documentation if the note only mentions nonspecific tearing.
Do not use for
Do not use H04.511 for left-sided or unspecified lacrimal stones, or for general nasolacrimal duct obstruction without a documented dacryolith. Check documentation when the finding is described as debris, infection, or another tear-duct disorder.
Coding tip
Confirm laterality and the word “dacryolith” in the record before assigning H04.511.
