Dacryolith of bilateral lacrimal passages

This code signifies the presence of a dacryolith, or lacrimal stone, affecting both the right and left lacrimal passages. These concretions can obstruct tear flow, leading to epiphora (excessive tearing), inflammation, and potential infection of the lacrimal system.

Apply this code when documentation clearly indicates the diagnosis of a dacryolith impacting both lacrimal ducts or sacs. Supporting documentation should include physician notes detailing the identification of lacrimal stones bilaterally, often confirmed by imaging studies or direct visualization during examination.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H04.511 or H04.512).
• Do not confuse dacryolithiasis with other lacrimal passage disorders like dacryocystitis (H04.3-) unless a dacryolith is explicitly identified as the cause.
• Consider sequencing this code with codes for any associated complications, such as dacryocystitis or conjunctivitis, if present and documented.
