Dacryolith of left lacrimal passage

This code signifies the presence of a dacryolith, or "tear stone," within the left lacrimal drainage system. These concretions can obstruct tear flow, leading to epiphora (excessive tearing) and potential infection.

Apply this code when documentation explicitly states a dacryolith is identified in the left lacrimal passage, such as the punctum, canaliculus, lacrimal sac, or nasolacrimal duct. This diagnosis is typically made through imaging (e.g., dacryocystography, CT scan) or direct visualization during examination or surgery.

• Ensure laterality is clearly documented as "left" to support this specific code.
• Do not confuse with dacryocystitis (inflammation of the lacrimal sac) unless a dacryolith is explicitly identified as the cause.
• If the dacryolith is removed, consider additional procedure codes for the removal.
