Dacryolith of unspecified lacrimal passage

This code describes the presence of a dacryolith, or lacrimal stone, within an unspecified part of the lacrimal drainage system. These concretions can obstruct tear flow, leading to epiphora, infection, or inflammation of the lacrimal sac or gland.

Use this code when documentation confirms a dacryolith is present but the specific location within the lacrimal passage (e.g., punctum, canaliculus, lacrimal sac, nasolacrimal duct) is not specified. This code is appropriate when the provider identifies a lacrimal stone without further anatomical detail.

• Avoid using this code if the specific location of the dacryolith is documented; instead, use a more specific code from the H04.51 subcategory.
• Ensure the documentation clearly states "dacryolith" or "lacrimal stone" rather than just "obstruction" to support this diagnosis.
• Consider sequencing this code with codes for associated conditions like dacryocystitis (H04.3-) or epiphora (H04.4-) if present.
