Dacryolith of right lacrimal passage

This code signifies the presence of a dacryolith, also known as a lacrimal calculus or tear duct stone, specifically located within the lacrimal passage of the right eye. These concretions can obstruct tear flow, leading to epiphora (excessive tearing), inflammation, and potential infection of the lacrimal drainage system.

Use this code when documentation clearly indicates a diagnosis of a dacryolith affecting the right lacrimal passage. This typically includes findings from ophthalmological examination, imaging studies (e.g., dacryocystography), or surgical reports confirming the presence and location of the stone.

• Ensure laterality is explicitly documented as "right" to support this specific code.
• Distinguish from dacryocystitis (inflammation of the lacrimal sac), which may be a consequence but is coded separately.
• Look for documentation of associated symptoms like epiphora, pain, or swelling to support medical necessity.
